them into the generated C++ code. device_class (Optional, string): The device class for the switch. For a coil it is write single coil. binary_sensor is the physical button on the Sonoff. From my perspective, I'm driving a relay which is a form of switch. timeout (Optional, Time): Time to wait before timing out. The script mode dictates what will happen if the set optimistic: true and then put your automations in here: turn_on_action:- switch.turn_on: switch2turn_off_action:- switch.turn_on: switch1. work even if the WiFi network is down or the MQTT server is not reachable. # Light will be kept on during 1 minute since, # can be called from different wall switches, Do Automations Work Without a Network Connection. delay action, wait_until action, or is inside a while loop, etc. This action toggles a switch with the given ID when executed. condition (Required, Condition): You could, for example, build a master light switch using several buttons to control every connected lightbulb in your smart home. A light does not need a switch. How about an input_boolean? To create an active-low switch (one that is turned off by default), use the Pin Schema: To create momentary switches, for example switches that toggle a pin for a moment, you can use advanced stuff (see the full API Reference for more info). publish_state(): Manually cause the switch to publish a new state and store it internally. Similarly, at reset time (before any of ESPHomes code runs) This allows using non-standard commands. script was already running. This effectively tells the YAML parser to treat the following By that logic, a switch should also be connected to an output - it is not, it directly triggers the GPIO. See Conditions. disabled_by_default (Optional, boolean): If true, then this entity should not be added to any clients frontend, state: Retrieve the current state of the switch. be performed when the remote (like Home Assistants frontend) requests the switch to be turned off. For the registers offset is the position of the relevant bit. Note that controlling everything strictly from the frontend is quite a pain. Would that example hide it from HA? Please note that its possible to achieve the same thing with the time.on_time will not be executed. With the button wired up, we can create a GPIO binary sensor in our configuration using the code below. In itself, the button or remote can not know if it opens invoked while it is still running from one or more previous invocations. can not be restored or if state restoration is not enabled. cycle back to its original state. Writing lambdas is not that hard! However one little drawback to this is that the input_boolean is not associated with the ESPhome device in the frontend. This is because the ESPs typically have issues in their network stacks that require a reboot to fix. state on boot-up and call the turn on/off actions with the recovered values. Finally, id() is a helper function that makes ESPHome fetch an object with the supplied ID (which you defined Requires Home Assistant 2022.3 or newer. Press J to jump to the feed. The entity_id in ESPHome does not have to be a component which is a sensor in Home Assistant, it can be anything. time period. 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 If we read the input on the pin the switch is connected to and press the switch, the pin will read LOW. ESPHome does not check the validity of lambda expressions you enter and will blindly copy I'd suggest this is a very likely use of this so would be useful to include it. later use it inside our awesome automation. The switch domain includes all platforms that should show up like a In some cases it is necessary to ensure that two outputs are never active at the same time. Defaults to doing nothing. customize everything about your node without having to dive into the full ESPHome C++ There is one caveat though: ESPHome automatically reboots if no connection to the MQTT broker can be This part is called a trigger. 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. int (for integers), float (for decimal numbers), int[50] for an array of 50 integers, etc. The component calculates the size of the range based on offset and size of the value type Requires Home Assistant 2021.9 or newer. A new version has been release since you last visited this page: 2022.6.2 . hopefully a bit easier to read and understand than Home Assistants. restore_state (Optional, boolean): Sets whether ESPHome should attempt to restore the 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. Sometimes youll also need a timer which does not perform any action, that is ok too, just id (Required, ID): The ID of the global variable to set. / 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 When using a lambda call, you should return the delay value in milliseconds. activate both switches at the same time. The condition to check. Toggle switches on the other hand stay in either the on or off position. entity_category (Optional, string): The category of the entity. of the sensor is within a certain range. Defaults to false. RESTORE_DEFAULT_ON - Attempt to restore state and default to ON. The crc is automatically calculated and appended to the command. In case scripts are run in parallel, this condition only tells you if at least one script tells ESPHome that the following block is supposed to be interpreted as a lambda, or C++ code. That was what I did in the original switch setup - can the same be done for a output setup? Defaults to doing nothing. (usually Home Assistant) without the user manually enabling it (via the Home Assistant UI). RESTORE_DEFAULT_OFF (Default) - Attempt to restore state and default to OFF if not possible to restore. here, the lambda: key would actually implicitly make the following block a lambda so in this context, Would it be possible to have ESPhome create the toggle, so it's associated with the ESP? [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). A simple push on this button should toggle the state of the dehumidifier. This action suspends execution of the automation until a script has finished executing. Another feature of ESPHome is that you can template almost every parameter for actions in automations. All these components are interchangable everywhere an output is used. Suppose you have this configuration file: With this file you can already perform some basic tasks. My thoughts were mainly that there should be something in the docs as it seems a common task that needs a solution. This action allows your automations to wait until a condition evaluates to true. 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. can write some basic (and also some more advanced) automations using a syntax that is You can also call this action from the script itself, and any subsequent action variables like so. For example, here all of the usual lambda syntax. to wait after other items in an interlock group have been disabled before re-activating. Links between the Momentary switch docs and the Button docs would also benefit users. For example, switch.toggle and the line after that form an interlock (Optional, list): A list of other GPIO switches in an interlock group. ALWAYS_ON - Always initialize the pin as ON on bootup. This action delays the execution of the next action in the action list by a specified Then you can use it in automations or Node-RED and make it do whatever you want. I would have guessed this output would be the Generic Switch Output. write_lambda (Optional, lambda): Lambda called before send. RESTORE_DEFAULT_ON - Attempt to restore state and default to ON. Well occasionally send you account related emails. For holding input registers the offset is in bytes. In this example the variable num_executions is incremented by one each time the ESP_LOGD("main","Modbus Switch incoming state = %f",x); // return false ; // use this to just change the value, payload.push_back(0x1); // device address, payload.push_back(0x5); // force single coil, payload.push_back(0x00); // high byte address of the coil, payload.push_back(0x6); // low byte address of the coil, payload.push_back(0xFF); // ON = 0xFF00 OFF=0000. My personal setup includes many Zigbee devices as well as integrations with existing products such as my Android TV box. !lambda lambda (Required, lambda): The lambda to run for instantiating the For example, this configuration would achieve your desired behavior: Woah, hold on there. modes queued and parallel, use value 0 for unlimited runs. a block until a given condition evaluates to false. return false; if the switch should be reported as OFF. My only thought is ensuring the relay is in a known state at start. for a list of available options. RESTORE_DEFAULT_OFF (Default) - Attempt to restore state and default to OFF if not possible to restore. optimistic (Optional, boolean): Whether to operate in optimistic mode - when in this mode, Note the terminology Liam Alexander Colman has been using Home Assistant for various projects for quite some time. It can be turned on and off by HA or by an automation in esphome. the delay is happening. You can adjust this behavior (or even disable automatic rebooting) using the reboot_timeout option restart: Start a new run after first stopping previous run. Sign in With it, you please consider the following setup (I omitted the general parts, not related to the switching or light part): There is no switch and the light component still switches the power on and off (through output). to interact with the script using the script actions. Because the offset for holding registers is given in bytes and the size of a register is 16 bytes the start_address is calculated as start_address + offset/2, A new version has been release since you last visited this page: 2022.6.2 . An example that uses a single relay to activate a remote control button. Like a gpio pin. See esp8266_restore_from_flash for details. You could write an automation to do this task in Home Assistants automation engine, but of the dehumidifier in your living room from Home Assistants front-end. ota.on_end / ota.on_error / restore_mode (Optional): Control how the switch attempts to restore state on bootup. The example below is an example of a custom switch; this custom switch is essentially the to your account. By that, I mean that you might have set the software switch to on while the hardware switch is in the off position. See Conditions. See Conditions. Hmm, I see your point, maybe I should move the GPIO stuff to a separate example below. queued: Start a new run after previous runs complete. You can also publish a state to a template switch from elsewhere in your YAML file If for example you want to only perform a certain What is an ESP32, and does ESPHome need its extra power? switch is the actual electrical relay It isnt an issue if the physical toggle switch is the only element controlling whatever device might be hooked up to the ESP8266 or ESP32. Defaults to no. / light.addressable_set, cover.open / cover.close / cover.stop / API. The time for which the condition has to have been true. The oscillation happens in the order of microseconds, and thus is easy for us to filter out with a few lines of code. In the first example, this range is defined as any value above or including See switch.on_turn_on / switch.on_turn_off Trigger. A switch can control many things, including other devices connected to the ESPHome node, such as an LED strip or a relay. Once defined, it will automatically appear in Home Assistant My thoughts were mainly that there should be something in the docs as it seems a common task that needs a solution. It can be turned on and off by HA or by an automation in esphome. Using this action you can manually call the update() method of a component. 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 . Use this were either returning COVER_OPEN or COVER_CLOSED to indicate that the cover is closed or open. 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. decided to also install a simple push button next to the dehumidifier on pin GPIO4. light is a component which is driven (and which drives) the output. then (Required, Action): The action to perform until the condition evaluates to false. use a single delay action, then in your automation check script.is_running condition The while action executes Since offset is not zero the read command is part of a range and will be parsed when the range is updated. binary_sensor.on_multi_click, esphome.on_boot / esphome.on_shutdown / esphome.on_loop, mqtt.on_message / mqtt.on_json_message / id (Optional, ID): Manually specify the ID used for code generation. esphome section. Within this block, you can define several actions. Read on to find out more on how I got started with Home Assistant. But I can't figure out what switch platform to use for this. The value for offset depends on the register type. I actually tried that but you have to set a turn_on action otherwise it would give me an error in Home Assistant. If payload is set in the lambda it is sent as a custom command and must include all required bytes for a modbus request After the chosen branch (then or else) is done with execution, the next action is performed. A press happens when you begin pressing the button/mouse. something like a window blind, a roller shutter, or a garage door.) condition (Required): The condition to check whether to execute. I am now trying to understand how from the ESPHome configuration I get the elements in the screenshot. in the wifi component and mqtt component. deactivate them. turns on a light for 5 seconds. Sure :) Lets step through whats happening here. If its different from the last internal state, its additionally published to the frontend. For the cases where the pure YAML automations dont work, This integration can be used to create custom switches in ESPHome the same principles apply here. offset from start address in bytes. time (Required, templatable, Time): true for at least a given amount of time. id (Optional, ID): Manually specify the ID used for code generation. Automations Is there a robust solution to ensure 'off' at startup? Already on GitHub? be performed when the remote (like Home Assistants frontend) requests the switch to be turned on. You can have an absolute timeout or sliding timeout by icon (Optional, icon): Manually set the icon to use for the The output switch platform allows you to use any output component as a switch. (You may also have seen variations of this like >- For example below you can see an automation that checks if a sensor value is below 30 and if so Too many different things all called output! Please explain whats going on here! But before you go https://esphome.io/components/switch/output.html, since I can toggle via the light component, does. Default to single. Defaults to never timing out. A note from the Momentary docs to this button might suffice? Wiring up a switch to an ESP8266 or ESP32, Configuring the internal pull-up resistor in ESPHome, supported device classes in Home Assistant, ESPHome 1.18.0 adds fingerprint readers, BME680 integration, and a BLE client. 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. using the C++ (Arduino) API. everything on your device with an easy-to-use syntax. Defaults max_runs (Optional, int): Allows limiting the maxiumun number of runs when using script Well, there are many different outputs. Like a gpio pin. ESP_LOGD("main", "I am at execution number %d", num_executions); // The sensor outputs values from 0 to 100. name (Required, string): The name of the switch. start or stop the motor of the gate. (Beware that effectively disables the reboot watchdog, so you will need to power cycle the device and requires Modbus Controller to be configured. initial_value (Optional, string): The value with which to initialize this variable if the state pin (Required, Pin Schema): The Defaults to 0. then (Required, Action): The action to perform. I really like toggle switches, but unfortunately, they arent very well suited to be used with ESPHome and Home Assistant. If you want to use a timeout, the term condition is required: condition (Required): The condition to wait to become true. turn_on_action (Optional, Action): The action that should What started off with a Raspberry Pi quickly became three Raspberry Pis and eventually a full-blown server. While ESPHome does not provide a construction for timers, you can easily implement them by Now that concludes the introduction to automations in ESPHome. The button can only RESTORE_INVERTED_DEFAULT_ON - Attempt to restore state inverted from the previous state and default to ON. 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). See Using custom_command how to use custom_command. 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. return {}; if the last state should be repeated. custom data must contain all required bytes including the modbus device address. Thats why, starting with ESPHome 1.7.0, theres a new automation engine. There are tactile or momentary switches, which are push buttons that are only engaged while they are being depressed. any command sent to the template switch will immediately update the reported state. When I first did this (as a momentary switch) it took me quite a while to find the right bit of the docs. turn_off_action (Optional, Action): The action that should An output button would probably also be useful, As I say, I am not fussed what the correct solution is, just I think there should be something in the docs . the switch is currently on or off: A new version has been release since you last visited this page: 2022.6.2 . ALWAYS_OFF - Always initialize the pin as OFF on bootup. an optional value lambda. A new version has been release since you last visited this page: 2022.6.2 . A switch is a switch and a light is a light. interlock_wait_time (Optional, Time): For interlocking mode, set how long on_turn_off (Optional, Action): An automation to perform By clicking Sign up for GitHub, you agree to our terms of service and This Condition allows you to check if a given condition has been They are usually operated by moving a lever to open or close an electrical circuit. lambda (Optional, lambda): This action allows you to stop a given script during execution. combining script and delay. payload (std::vector&payload): empty vector for the payload.
