A list of IDs that uniquely identify the device. Thanks! You can add it to the appropriate section of your configuration.yaml, or you can add it as a Home Assistant Packageopen in new window by adding the following to zigbee2mqtt.yaml in your packages folder. Also make sure to change the port of the mqtt broker. topic (Required, string): The MQTT topic to subscribe to and listen for MQTT to the broker is dropped. template, the message payload is available under the name x inside that lambda. If you want to purge on another The device specific configuration allows you to modify the discovery payload. to use. ///state. The time in seconds between sending keep alive messages for this client. Can be one of none or device_name. This is the easiest to set up, but there is no privacy as all messages are public. To use the message content, use a lambda Still, Id very much prefer having an ability to simply add a sensor in HA via a remote MQTT with simple means. the MQTT connection is dropped. To my knowledge its discovery feature cannot be used to control home-assistant native entities. broker (Required, string): The host of your MQTT broker. 2- The IP address of my Home Assistant is 192.168.1.150, does the broker also have this address? Default to false. You havent said what type of system youre running, or which MQTT software you use, but it might be possible for you to make your own simple MQTT bridge by piping the output of an MQTT subscriber client into a publisher client. Would it be a better solution to create an automation that translates the mqtt messages into events and then use the events as triggers? Basically, you can access elements by typing x["THE_KEY"] and save them into local variables. My second question is: How do I convert them? certificate_authority (Optional, string): Only with esp-idf. Home Assistants default prefix homeassistant. I also use a MQTT to IR device have a look at my scripts examples: For the HTTP have a look at https://home-assistant.io/components/rest_command/. I do bridge currently which although confusing at first works very well. All components in ESPHome that do some sort of communication through To use the public mosquitto broker, confiure the MQTT integration to connect to broker test.mosquitto.org on port 1183 or 8883. Then I can use an automation for when the sensor detects one of the desire codes to do whatever I want. '{{ "single" == trigger.payload_json.click }}', # OR if your devices has multiple endpoints (e.g. performed when a JSON message on a specific MQTT topic is received. payload (Required, string): The message content. All I can find is some complicated solution where I must bridge MQTT or what not, isnt there a simple way to just get sensor data from a remote MQTT broker? Set the verification of the server hostname in the server certificate. Abbreviations Only if exactly the payload The discovery topic needs to be: /device_automation/[/]/config. Next, enable multiple devices use the same name for a sensor, making it harder to distinguish between availability (Optional): Manually set what should be sent to The mosquitto broker package ships commandline tools (often as *-clients package) to send and receive MQTT messages. mac generator uses format --. An MQTT device trigger is a better option than a binary sensor for buttons, remote controls etc. No way around it. Will be filled by the actual payload with some Home Assistant contains a WebSocket API. does not generate object_id. Then I have my Home Assistant which contains this switch: I can see its nice UI element and there isnt anything MQTT related with this switch: So what I would like is to be able to press this physical push button and this would instruct home assistant to remote control this switch and turn the connected light/device behind it on/off. Note irony. For other types you have to manually create a config in the Home Assistant configuration.yaml. Also note that the combination of type and subtype should be unique for a device. Support for esp-idf is still experminental. With the MQTT Message schema you can tell ESPHome how a specific MQTT message should be sent. to use. trigger a compile failure. Enter something similar to the example below into the topic field under Publish a packet and press PUBLISH . For testing I leave the unencrypted port open to localhost only. for more information. button_1 spammed with type set to spammed and subtype set to button_1, The subtype of the trigger, e.g. Identifier of a device that routes messages between this device and Home Assistant. From system 2 my home assistant receives http post requests. In an optimal scenario I wouldnt need to write this automation to every device I want to control. Perfect to run on a Raspberry Pi or a local server. command_topic (Optional, string): The topic to subscribe to for and with some computing power the fingerprint can be faked. will show all its entities as unavailable (a feature ). Only thing you could do (to get at lease some visual representation in the UI) is to create a MQTT Binary Sensor for the MQTT push button. All other features of ESPHome I think that in this case I will go with the REST api to feed the data into HA andwith the mqtt_statestream to feed the data out from HA. performed when a message on a specific MQTT topic is received. Have a look at creating a mqtt bridge. This is a problem. To achieve the best possible integration (including MQTT discovery): Since Home Assistant 2021.11 the device/group page in Home Assistant can directly link to the frontend (Visit device button). the node shuts down and the connection is closed cleanly. The JSON message will be constructed using the ArduinoJson library. have a retain flag on or not. With this configuration option you can write complex automations whenever an MQTT That is one reason why i had the idea that it would be a better idea to model external events like the pushing of a button as ha events. Defaults port (Optional, int): The port to connect to. If you are connecting to Home Assistant, you may prefer to use the native API, If set to an unsupported value, will render as subtype type, e.g. client_id (Optional, string): The client id to use for opening For sending test messages to a broker running on localhost check the example below: Another way to send MQTT messages manually is to use the MQTT integration in the frontend. reboot_timeout (Optional, Time): The amount of time to wait before rebooting when no Usually these are .crt files and you can open them with any text editor. Defaults to homeassistant. ESPHome anymore. I'm guessing I'll still have to install the broker locally even if I don't use it. topic_prefix if you have specified it manually. I guess MQTT is a light enough protocol I don't have to worry about running a broker I don't need. If set to an unsupported value, will render as subtype type, e.g. How could I use the http requests to trigger state changes? In the instance of Ubuntu this would be certificate: /etc/ssl/certs/ca-certificates.crt. This works for me even if I have the feeling that there should be a more elegant way to do it. making it easier to distinguish the entities in various entity lists. Suggest an area if the device isnt in one yet. Note that it is not necessary to provide the full device information in each message, but the identifying information, identifier in the example, must be the same. See MQTT Switch for example. Then I set the expire_after attribute to 1 second. BUT You could use the websocket interface or the REST api to do those things: Home Assistant provides a RESTful API on the same port as the web frontend. If I do it your way then the following would happen: When I push the same botton on my remote control severall times then only the first pressing is detected because the state would be on after the first pushing and it wouldnt change if I pushed the button again. message on a specific topic is received. When using Home Assistant MQTT discovery, Zigbee2MQTT integrates with the Home Assistant device registryopen in new window. topic (Required, string, templatable): if (id(reed_switch).state) return "topic1"; return id(reed_switch).state ? in ESPHome MQTT integration configuration will cause Home Assistant to include device name ESPHome uses the last will My cloud mq server is running SSL for external traffic. Thanks for your quick reply. I am quite new to HA and I am struggling with the best way to model manual remote controls. skip_cert_cn_check (Optional, bool): Only with esp-idf. Maybe its the problem. log_topic (Optional, MQTTMessage): The topic to send MQTT log Defaults to 15 seconds. qos (Optional, int, templatable): The Quality of on_message (Optional, Automation): An action to be By default, ESPHome will prefix all messages with your node name or the MQTT broker. Are you saying that HA definitely cant support dual/mutual brokers though as this was of interest to me too especially if trying to bring in a public brokers info ? have a retain flag on or not. A list of connections of the device to the outside world as a list of tuples [connection_type, connection_identifier]. If this would work then it would match my requirement to eliminate the need to hand-craft automation scripts for every device. button_short_press. You would want to use SSL if you are using mqtt over WAN. Defaults to the global default. name part of the generated entity name. If you experience an error message like Failed to connect due to exception: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed, then add certificate: auto to your broker configuration and restart Home Assistant. Ive already found hass_statestream which publishes mqtt messages when I use these entities from my HA. Hello @sejnub and welcome to your community! Please The client ID that Home Assistant will use. Defaults to If I try to add extra broker lines in my configuration.yaml, HA logs a warning and only connects to the last broker Ive listed. MQTT connection exists. I verified that Im able to do this: and this gets the job done. Default derived from Please note that its a good idea to check if the key exists in the Json Object by calling Here you can also prevent a device from being discovered. entity name (e.g. to have Home Assistant discover your devices on restart, all discovery I feel all I find is waaaay too complicated for a single sensor solution? Basically what Im looking is a reverse of mqtt_statestream: a way to just as easily let Home Assistant automatically listen to mqtt topics for remote control without having to manually declare configuration yaml/automation for each individual entity. And now I am trying to find the right way to write automations that convert these external button pushes (which enter ha via mqtt and http) into ha events.But I am really strugging with the documentation on event actions and the questions if event data should be json. Note that only one trigger may be defined per unique discovery topic. In the payload option you have access to a root object which will represents the base object Discovery topic: homeassistant/device_automation/0x90fd9ffffedf1266/action_arrow_left_click/config, Trigger topic: zigbee2mqtt/0x90fd9ffffedf1266/action, Discovery topic: homeassistant/device_automation/0x90fd9ffffedf1266/action_arrow_right_click/config, The MQTT Device Trigger integration was introduced in Home Assistant 0.106, idf_send_async (Optional, bool): Only with esp-idf. I ended up just giving up and looking into how to set up a bridge with my local MQTT server. qos (Optional, int): The MQTT Quality of Service to subscribe to the topic with. System 2 can make a http request when a button is pressed on the remote. topic_prefix (Optional, string): The prefix used for all MQTT I also tried experimenting with mqtt_statestream to see if I could craft an MQTT message like this: but for some reason I couldnt get this working. Note that you can have unencrypted mqtt running on the normal port and just don't expose it on the firewall. qos (Optional, int): The Quality of You have to download the server CA certficiate in PEM format and add it to certificate_authority. Publish an MQTT message on a topic using this action in automations. Defaults to false. Press question mark to learn the rest of the keyboard shortcuts, https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-the-mosquitto-mqtt-messaging-broker-on-ubuntu-16-04. Powered by Discourse, best viewed with JavaScript enabled. The type of automation, must be trigger. Service Empty (the default) means no authentication. I installed the MQTT add-on. Defaults to none which MQTT sensor msg dont need to be in json, take a look at the MQTT sensor docs https://home-assistant.io/components/sensor.mqtt/ the very last example of the brightness isnt in json. Should not contain trailing slash. However, as of today, there is no way to have HA monitor MQTT topics to turn on/off switches via command. discovery_retain (Optional, boolean): Whether to retain MQTT From my understanding you want to control your MQTT device with Home Assistant, is that is so, the best way is to make a Script: https://home-assistant.io/components/script/ and it's used by. It turned out only requiring an hour or two of work. With renote access, do you mean remote in network outside your home network or outside of the machine running Home Assistant but in your home network? The following is an example lovelace card configuration. This shows a complete example of defining a remote control type device with two triggers: left arrow click and right arrow click. Groups discovery is supported for groups of lights, switches, locks and covers. Ive an error (connection refused) when I try to publish a message. If you enable MQTT and you do not use the native API for Home Assistant, you must 3- A solution? The MQTT Client Component sets up the MQTT connection to your broker. See on_message Trigger. Path to the certificate file, e.g., /ssl/server.crt. messages to. you specify with this option is received, the automation will be executed. The recommended setup method is to use the Mosquitto MQTT broker add-on. Optional payload to match the payload being sent over the topic. address of your device to it. In the Listen to a topic field, type # to see everything, or home-assistant/switch/# to just follow a published topic, then press START LISTENING. state_topic (Optional, string): The topic to publish state If true publishing the message happens from the internal mqtt task. of the JSON message.

The servers CA certificate is required to validate the connection. "YES" : "NO"; # {"key": 42.0, "greeting": "Hello World"}. This allows Zigbee2MQTT to automatically add devices to Home Assistant. You can even specify multiple on_message triggers by using a YAML list: With this configuration option you can write complex automations whenever a JSON-encoded MQTT password (Optional, string): The password to use for That way, you can use your existing wildcards like Although I cant think of a theoretical reason why one system ought not to be able to directly connect to more than one broker, Im not familiar enough with the code to know how much effort it would take to make multiple brokers work. The advantage of asyncronous publishing is that it doesnt block the esphome main thread. /+/NODE_NAME/#. Additionally, SHA1 is known to be partially insecure When adding new entities, you might run into trouble with old entities I cant see any hint in the documentation or code that the MQTT integration is supposed to support more than one broker. To enable this set the url in the frontend configuration. name (Required, string): The name to use for the MQTT By default it connects with 3.1.1 and falls back to 3.1 if server does not support 3.1.1. The mqtt device trigger platform uses an MQTT message payload to generate device trigger events. will_message (Optional, MQTTMessage): The message to send when Therefore the old entities will also Doing the steps here will enable ssl. Some broker configuration options cant be set via the user interface, but require changes of your configuration.yaml file.
