I really like toggle switches, but unfortunately, they arent very well suited to be used with ESPHome and Home Assistant. Wiring up a switch or button to an ESP8266 or ESP32 is one of the most basic things you can do. This action executes an arbitrary piece of C++ code (see Lambda). By that, I mean that you might have set the software switch to on while the hardware switch is in the off position. When I first did this (as a momentary switch) it took me quite a while to find the right bit of the docs. Just to say in the doc you have created, it is a little unclear which block the 'Configuration Variables' refers to (output or button). Or with some YAML anchors you can further simplify the config: These are software interlocks. Lets look at an example is above 65%, and make it turn off again when it falls below 50%: Thats a lot of indentation on_value_range is a special trigger for sensors that trigger when the value output

turns on a light for 5 seconds. state (Required, boolean, templatable): There is no example of a momentary switch on the Button documentation. RESTORE_INVERTED_DEFAULT_ON - Attempt to restore state inverted from the previous state and default to ON. The goal is that the pin to which the switch is connected reads LOW when the switch is pressed and HIGH whenever it isnt being pressed. You can pick from any of the supported device classes in Home Assistant: There is one issue with this setup, though. My goal is that any ESPHome beginner will be able to wire up a switch or button and configure it using YAML. a switch. The condition to check. With templates inside ESPHome, you can do almost everything. We now attach a special attribute on_press to the toggle button. All that needs to be added is one line of YAML: With the setup above, ESPHome will report the switch to be off when the switch is pressed and on whenever it isnt pressed. sonoff offset from start address in bytes. I would have guessed this output would be the Generic Switch Output.

controlling everything strictly from the frontend is quite a pain. This action turns a switch with the given ID on when executed. switch and can only be turned ON or OFF. ESP_LOGD("main", "I am at execution number %d", num_executions); // The sensor outputs values from 0 to 100. light is a component which is driven (and which drives) the output. payload (std::vector&payload): empty vector for the payload.

For that reason, I advise against using toggle switches on ESPHome projects, even if they are fun to play around with. The other coils follow toward the high-order end of this byte and from low order to high order in subsequent bytes. with lambdas, its always best to look at the generated C++ source file under /src/main.cpp. In some cases it is necessary to ensure that two outputs are never active at the same time. ESP8266 and ESP32 boards have built-in pull-up resistors, which can be enabled in the ESPHome configuration. value (Required, templatable): The value to set the global esphome mqtt esp8266 after it switched See Press question mark to learn the rest of the keyboard shortcuts, https://esphome.io/components/switch/template.html. For coil and discrete input resisters the LSB of the first data byte contains the coil addressed in the request. For holding input registers the offset is in bytes. Add Momentary Switch example and link to Button Documentation. It can be turned on and off by HA or by an automation in esphome. work even if the WiFi network is down or the MQTT server is not reachable. the switch is currently on or off: A new version has been release since you last visited this page: 2022.6.2 . The state to publish. esphome hopefully a bit easier to read and understand than Home Assistants. Defaults to false. For example, with the output button I made it's also possible to trigger a Bluetooth signal. using the C++ (Arduino) API. id (Required, ID): The ID of the script. sonoff esphome execute the script with a single call. Interlocking. decided to also install a simple push button next to the dehumidifier on pin GPIO4. But as soon as you pass things on to Home Assistant and also want to control your device from the dashboard, things can get out of sync. You could write an automation to do this task in Home Assistants automation engine, but Theyre a powerful tool to automate almost Within this block, you can define several actions. Requires Home Assistant 2021.11 or newer. A new version has been release since you last visited this page: 2022.6.2 , switch.on_turn_on / switch.on_turn_off Trigger, // Within lambda, make the switch report a specific state, // Within lambda, get the switch state and conditionally do something, https://developers.home-assistant.io/docs/core/entity/#generic-properties, https://developers.home-assistant.io/docs/core/entity/switch/#available-device-classes. ESPHome always initializes outputs to off on boot. switch is the actual electrical relay

register_type (Required): type of the modbus register. Useful for motors where immediately turning on in the other direction could cause problems. The modbus_controller switch platform creates a switch from a modbus_controller component Without it, the YAML parser would attempt to read the following block as if id (Optional, ID): Manually specify the ID used for code generation. entity_category (Optional, string): The category of the entity. However, it looks like the doc you have created is a GPIO Output, that doesn't. of hiding one of them when the switch is ON/OFF. deactivate them. To be used for what has been described in this guide. See switch.on_turn_on / switch.on_turn_off Trigger. lambda (Required, lambda): The lambda to run for instantiating the count (Required, int): The number of times the action should be repeated. turn_off()/turn_on(): Manually turn the switch ON/OFF from code. item (const pointer to a Switch derived object): The sensor object itself. Sorry, if this sounds dumb, but I can't figure this out: I want to integrate a switch that can be toggled from within Home Assistant. There are tactile or momentary switches, which are push buttons that are only engaged while they are being depressed. Would it be possible to have ESPhome create the toggle, so it's associated with the ESP? Yes, that's true, but maybe instead of exposing the state to allow the user to check it, it's better if we force it to be off on startup. ota.on_state_change, script.execute / script.stop / script.wait, switch.toggle / switch.turn_off / switch.turn_on, light.toggle / light.turn_off / light.turn_on As restore_mode is not in the example, it would be unclear if that was part of the output block or the switch block. an optional value lambda.

My thoughts were mainly that there should be something in the docs as it seems a common task that needs a solution. The final command will be write_single_coil address 5 (start_address+offset) value 1 or 0, For holding registers the write command will be write_single_register. An example that uses a single relay to activate a remote control button. But before you go Sure :) Lets step through whats happening here. Or you can pass on the status of the switch or button to Home Assistant and have it control any of the devices you have integrated. Defaults There's no restore_mode, as there's no restore mode for buttons (nor for outputs), and there's no switch involved at all. set optimistic: true and then put your automations in here: turn_on_action:- switch.turn_on: switch2turn_off_action:- switch.turn_on: switch1. A switch can control an output, see https://esphome.io/components/switch/output.html, Powered by Discourse, best viewed with JavaScript enabled. Now comes the actual automation block. The button can only If compilation fails or something else is not working as expected turn_off_action (Optional, Action): The action that should optimistic (Optional, boolean): Whether to operate in optimistic mode - when in this mode, If you want to use a timeout, the term condition is required: condition (Required): The condition to wait to become true. The relay simulates the button press for 500ms. on_turn_on trigger. mqtt.on_connect / mqtt.on_disconnect, ota.on_begin / ota.on_progress / While ESPHome does not provide a construction for timers, you can easily implement them by when the switch is turned off. / media_player.volume_up / media_player.volume_down / media_player.volume_set, binary_sensor.is_on / binary_sensor.is_off, wifi.connected / api.connected that two GPIOs are never active at the same time. were either returning COVER_OPEN or COVER_CLOSED to indicate that the cover is closed or open. An output is anything that can output a signal: a GPIO pin, an AC dimmer, various I/O port expanders, or even something more higher level such as Bluetooth signal. Commentdocument.getElementById("comment").setAttribute( "id", "ad275e46d456ee4a330ab42f3b0a6290" );document.getElementById("c08a1a06c7").setAttribute( "id", "comment" ); I have read and accept the Privacy Policy. (Beware that effectively disables the reboot watchdog, so you will need to power cycle the device The script mode dictates what will happen if the Thank you for your contributions. right after the switch component has acknowledged the state (e.g. return ; the new value for the sensor. to false. In this example, the device class is set to be a window. max_runs (Optional, int): Allows limiting the maxiumun number of runs when using script Thats why, starting with ESPHome 1.7.0, theres a new automation engine. sensor in the frontend. Note that lambda is executed and the current value is logged.

See https://developers.home-assistant.io/docs/core/entity/#generic-properties This action allows your automations to wait until a condition evaluates to true. start or stop the motor of the gate. This Action allows you to change the value of a global variable without having to go through the lambda syntax.

You can also publish a state to a template switch from elsewhere in your YAML file The gpio switch platform allows you to use any pin on your node as a Because of this, it ESPHome can sometimes read the wrong values (such as a very rapid switching from one value to the other before it finally switches). Theres a slight difference in how these different styles deal with whitespace, but for our internal (Optional, boolean): Mark this component as internal. executes the then: branch or the else: branch depending on the output of the condition. In this example, Lambda to be evaluated every update interval to read the status of the switch. If its different from the last internal state, its additionally published to the frontend. This action first evaluated a certain condition (if:) and then either Being able to properly configure a physical switch or button in ESPHome is one of the fundamental things you should be able to do when planning projects. x (float): The float value to be sent to the modbus device. // part of the light color will be determined by the sensor value. The text was updated successfully, but these errors were encountered: A better implementation would be something like this, that avoids the unnecessary switch: Momentary switches in general are a hack from when buttons didn't exist, so I'd rather remove them from the documentation than make them more prominent. on_turn_on (Optional, Action): An automation to perform automation if a certain complex formula evaluates to true, you can do that with templates. type (Required, string): The C++ type of the global variable, for example bool (for true/false), in the wifi component and mqtt component. the automation in the next few lines will execute whenever someone begins to press the button. a block until a given condition evaluates to false. From lambdas, you can call several methods on all switches to do some timeout (Optional, Time): Time to wait before timing out. In lambdas youre effectively writing C++ code and therefore the Only specifying an id without You can for example hook up a relay to a GPIO pin and use it This action delays the execution of the next action in the action list by a specified See switch.on_turn_on / switch.on_turn_off Trigger. use_write_multiple (Optional, boolean): By default the modbus command Force Single Coil (function code 5) is used to send state changes to the device. The bitmask is used to determined if the result is true or false. In this case, Please note that its possible to achieve the same thing with the time.on_time controlled by a template, or lambda. You can control the ON/OFF state RESTORE_DEFAULT_OFF (Default) - Attempt to restore state and default to OFF if not possible to restore. for a list of available options. Well occasionally send you account related emails. 65.0, and the second one refers to once the humidity reaches 50% or below.

For restoring on ESP8266s, also see esp8266_restore_from_flash in the time period. ESPHome has a feature to prevent two GPIO Switches from being active at the same time called First, we have to give the dehumidifier a ID so that we can / stepper.set_speed, output.esp8266_pwm.set_frequency / output.ledc.set_frequency, mhz19.calibrate_zero / mhz19.abc_enable / mhz19.abc_disable, http_request.get / http_request.post / http_request.send, number.set / number.to_min / number.to_max / number.decrement / number.increment / number.operation, select.set / select.set_index / select.first / select.last / select.previous / select.next / select.operation, media_player.play / media_player.pause / media_player.stop / media_player.toggle esp8266 section. A sensor or binary_sensor sense something, not switch it. [edit] Just to say in the doc you have created, it is a little unclear which block the 'Configuration Variables' refers to (output or button). By clicking Sign up for GitHub, you agree to our terms of service and For data points that dont change very frequently updates can be skipped. As such, a software bug (which can always happen) can still cycle back to its original state.

All these components are interchangable everywhere an output is used. In electronics, this is called debouncing. template cover. ESPHome does not check the validity of lambda expressions you enter and will blindly copy the first parentheses evaluates to true then execute the first block (in this case return COVER_OPEN;, A new version has been release since you last visited this page: 2022.6.2 . can not be restored or if state restoration is not enabled. My personal setup includes many Zigbee devices as well as integrations with existing products such as my Android TV box. / text_sensor.template.publish, stepper.set_target / stepper.report_position A note from the Momentary docs to this button might suffice? Following up on a question about switch vs light in a Sonoff running ESPHome, I ended up with the following configuration: The last switch is the light one, the one before is the switch. The switch domain includes all platforms that should show up like a Note: If no script is executing, this will continue immediately. After the chosen branch (then or else) is done with execution, the next action is performed. A new version has been release since you last visited this page: 2022.6.2 . This is useful right now if your want to stop a script that contains a Defaults to false. For the registers offset is the position of the relevant bit. Similar to the switch.turn_on and switch.turn_off actions, global variables can be used to store the state of a garage door. Please explain whats going on here! My only thought is ensuring the relay is in a known state at start. The state of the template cover is When using a lambda call, you should return the delay value in milliseconds. Defaults to doing nothing. For example below you can see an automation that checks if a sensor value is below 30 and if so For example mode (Optional, string): Controls what happens when a script is condition (Required): The condition to check whether to execute. If payload is set in the lambda it is sent as a custom command and must include all required bytes for a modbus request name (Required, string): The name for the switch. follows what you would call these events on mouse buttons. You could, for example, build a master light switch using several buttons to control every connected lightbulb in your smart home. This action turns a switch with the given ID off when executed. Defaults to doing nothing. Like this: https://i.imgur.com/oxXGGfh.png, I'd probably go with a template switch: https://esphome.io/components/switch/template.html. This action allows you to stop a given script during execution. id (Required, ID): Give the global variable an ID so that you can refer The write command to be constructed uses the function code to determine the write command. An output is the conduit between the light component and the real world. This action toggles a switch with the given ID when executed. Have a question about this project? This condition allows you to check if a given script is running. invoked while it is still running from one or more previous invocations. return {}; in the case the lambda handles the sending of the value itself. Please first read Custom Sensor Component guide, Hmm, I see your point, maybe I should move the GPIO stuff to a separate example below. My thoughts were mainly that there should be something in the docs as it seems a common task that needs a solution. if it fails to connect to the network without a reboot), sensor.on_value / sensor.on_raw_value / sensor.on_value_range, binary_sensor.on_press / binary_sensor.on_release / not be exposed to the frontend (like Home Assistant). ALWAYS_OFF - Always initialize the pin as OFF on bootup. or closes the gate. interval (Required, Time): The interval to execute the action with. Toggle switches on the other hand stay in either the on or off position. Be careful: on the ESP8266, you only have a total of 96 bytes available for this! I feel all of the output needs a bit of rework so it is consistent and I think a general intro section to outputs would also help, including things like how they are initialised, the fact they need 2 parts etc. If your device only supports Force Multiple Coils (function code 15) set this option to true. Example Binary Light - firstly it is defined in a different order in the example (which I realise in itself doesn't matter but I'm a sucker for consistency), but also should it be an Output Light (rather than Binary Light) to follow the same logic? RESTORE_DEFAULT_ON - Attempt to restore state and default to ON. Defaults to Then you can use it in automations or Node-RED and make it do whatever you want. // Acknowledge new state by publishing it. custom data must contain all required bytes including the modbus device address. It will be closed if no further activity occurs. This action suspends execution of the automation until a script has finished executing. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Finally, id() is a helper function that makes ESPHome fetch an object with the supplied ID (which you defined If we read the input on the pin the switch is connected to and press the switch, the pin will read LOW. lambda (Optional, lambda): here, the lambda: key would actually implicitly make the following block a lambda so in this context, something like a window blind, a roller shutter, or a garage door.) The difference seems subtle, but it's important: it is a switch that uses an output, not an output that uses a switch. device_class (Optional, string): The device class for the switch. So it is highly recommended to use hardware interlocks (like SPDT-type relays) that ensure I've implemented the output button with documentation for the next release (see here), but I'll leave this one open as something should also be done with the Momentary Switch section. like so: With this automation, a press on the push button would cause the dehumidifier to turn on/off for 2 seconds, and then

to it later in lambdas. esphome section. The platform used is really an HA thing and helps HA determine what to do with the entity which is also an important concept. See esp8266_restore_from_flash for details. cover.control, output.turn_off / output.turn_on / output.set_level, deep_sleep.enter / deep_sleep.prevent / deep_sleep.allow, sensor.template.publish / binary_sensor.template.publish restore_mode (Optional): Control how the switch attempts to restore state on bootup. For a coil it is write single coil.

were retrieving the current state of the end stop using .state and using it to construct our cover state. Using this filter will only make the signal go high if the button has stayed high for more than 10ms, which should be more than enough to filter out the oscillation. ESPHome has another extremely powerful tool to offer: Templates.

I wouldn't want a random 'on' (which would open the garage door) on boot .

I do agree it would be nice if there's some high-level introduction about how the different platforms (outputs/switches/buttons/etc) relate to each other, but that's not related to this particular implementation. ALWAYS_ON - Always initialize the pin as ON on bootup. However, once we release the switch, there is no guarantee that the pin will read HIGH. The blue. switch(es). The example I show uses a GPIO Output, but it could use any other output as well. Is there a robust solution to ensure 'off' at startup? This will make the Home Assistant frontend show buttons for both ON and OFF actions, instead output is an internal status of GPIO13 I am not sure of this one But I can't figure out what switch platform to use for this. Internal components will This action allows you to repeat a block a given number of times.

the MQTT server being offline. same as the gpio switch implementation. return ; and fill payload with data if the payload is added from the lambda then these bytes will be sent. publish_state(): Manually cause the switch to publish a new state and store it internally. ON/OFF itself). To get the value of the coil register 2 can be retrieved using address: 2 / offset: 0 or address: 0 / offset 2. bitmask (Optional, int): Some values are packed in a response. state: Retrieve the current state of the switch. If more than one register is read a modbus read registers command this value is used to find the start of this datapoint relative to start address.

You signed in with another tab or window. This needs to be wrapped in quotes! A simple push on this button should toggle the state of the dehumidifier. This action can also be written in lambdas, the parameter of the public_state method denotes if Defaults to false. custom_command (Optional, list of bytes): raw bytes for modbus command. A new version has been release since you last visited this page: 2022.6.2 . else (Optional, Action): The action to perform if the condition evaluates to false. script was already running. Automations Possible return values for the optional lambda: return true; if the switch should be reported as ON. In the first example, this range is defined as any value above or including / light.control / light.dim_relative But I guess I would have to have to create the boolean helper in HA, right? interlocking. The wiring of a switch is rather simple. API. You can also call this action from the script itself, and any subsequent action Since offset is not zero the read command is part of a range and will be parsed when the range is updated. Note the terminology Set to "" to remove the default entity category. The while action executes It makes sense that they're all called output, because at a high level they all do the same. Lambda to be evaluated repeatedly to get the current state of the switch. Next, theres the weird |- character combination. it were made up of YAML keys like cover: for example. But that is just cosmetic Home Assistant Sensor or Home Assistant Binary Sensor.
