See TLS with esp-idf (esp32) for more information. 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. To change the settings, click on Configure in the integration page in the UI, then Re-configure MQTT. This is a problem. Here I am really lost. Defaults to false. Otherwise no devices could connect it. This Condition checks if the MQTT client is currently connected to Defaults to See Device specific configuration for the available options. port (Optional, int): The port to connect to. Enter something similar to the example below into the topic field under Publish a packet and press PUBLISH . That is basically the summary of the referenced MQTT switch integration. 3- A solution? The x object is of type JsonObject by the ArduinoJson options, like log_topic. Please note that its a good idea to check if the key exists in the Json Object by calling To fix this, ESPHome has a simple helper script that purges stale Can be either an HTTP or HTTPS link. Ive to use a username and a password? ///command. commands from the remote. messages on. However, as of today, there is no way to have HA monitor MQTT topics to turn on/off switches via command. payload (Required, lambda): The message content. System 2 can make a http request when a button is pressed on the remote. But its all working fine now and I guess with it all in place, that its a logical solution. a connection to the broker is established. client_id (Optional, string): The client id to use for opening Home Assistant contains a WebSocket API. discovery (Optional, boolean): If Home Assistant automatic It turned out only requiring an hour or two of work. Please Empty (the default) means no authentication. Thanks for the idea. To get this fingerprint, first put the broker and port options in the configuration and In the instance of Ubuntu this would be certificate: /etc/ssl/certs/ca-certificates.crt. Have a look at creating a mqtt bridge. When using Home Assistant MQTT discovery, Zigbee2MQTT integrates with the Home Assistant device registryopen in new window. Entries supported by the frontend: button_short_press, button_short_release, button_long_press, button_long_release, button_double_press, button_triple_press, button_quadruple_press, button_quintuple_press. This works for me even if I have the feeling that there should be a more elegant way to do it. payload (Required, string, templatable): The message content. Ive got a local MQTT server configured in HA for some random crap Im doing. The automation snipped I posted earlier allows me to do this and I can live with this approach, albeit its not an optimal one. if (id(reed_switch).state) return "topic1"; return id(reed_switch).state ? With this configuration option you can write complex automations whenever an MQTT as seen below. qos (Optional, int, templatable): The Quality of Home Assistants default prefix homeassistant. Defaults to 15min. PS : OpenZwave is working, I presume that if I change the password, I must re configure OpenZwave? ssl_fingerprints (Optional, list): Only on ESP8266. . Or would it again be a better solution to create events? Defaults to true. be retained. How could I use the http requests to trigger state changes? topic (Required, string): The MQTT topic to subscribe to and listen for MQTT Here I have some problems because ha generates incorrect json using single quotes and not double quotes. For example with the delay action. See Last Will And Birth Messages for more information. device_name generator uses format _. To use the public mosquitto broker, confiure the MQTT integration to connect to broker test.mosquitto.org on port 1183 or 8883. in which case this is not needed. for the two brokers, but running something like the above in the background should forward the subscribed topic from the remote broker onto your chosen topic on your local broker. Most brokers use port 8883 for TLS connections. global birth/last will message. Defaults to the global default. 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? CA certificate in PEM format. A list of connections of the device to the outside world as a list of tuples [connection_type, connection_identifier]. Defaults to none which Defaults to 0. retain (Optional, boolean): If the published message should birth_message (Optional, MQTTMessage): The message to send when sensor.uptime becomes sensor._uptime), message is received. The most private option is running your own MQTT broker. does not generate object_id. If set, this name will be used instead of friendly_name. Maybe its the problem. 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, Powered by Discourse, best viewed with JavaScript enabled, yes, it is. Still, Id very much prefer having an ability to simply add a sensor in HA via a remote MQTT with simple means. /status with payload online, and will tell the The discovery topic needs to be: /device_automation/[/]/config. I believe, and I might very well be misunderstanding this very badly, but the MQTT Switch integration is used if I have a plug (I guess these can also be confused as switches) such as this https://www.ikea.com/gb/en/p/tradfri-wireless-control-outlet-00364477/ which is able to receive MQTT messages to turn the relay inside the plug to either ON or OFF. If you enable MQTT and you do not use the native API for Home Assistant, you must Optional payload to match the payload being sent over the topic. I have two systems with manual remote controls which i want to integrate into home assistant. I was wrongly assuming, that the MQTT push button is the MQTT switch. That's what I assumed I'd have to do. If you only plan to use this and want to disable the Via Home Assistant entity integration below, set homeassistant: {legacy_triggers: false} (see Configuration for more info). To give some background: I have a remote physical touch screen where Im building a small GUI to control some aspects of my home automation. 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. 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 ? shutdown_message (Optional, MQTTMessage): The message to send when You would want to use SSL if you are using mqtt over WAN. For example a serial number. certificate_authority (Optional, string): Only with esp-idf. 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. Entries supported by the frontend: turn_on, turn_off, button_1, button_2, button_3, button_4, button_5, button_6. The JSON message will be constructed using the ArduinoJson library. If this would work then it would match my requirement to eliminate the need to hand-craft automation scripts for every device. You can create quasi-virtual switches that are represented in MQTT via the MQTT switch (which you already did) that will turn on/off a physical switch in HA. This is because in order connections. If you want to prefix all MQTT messages with a different prefix, like Zigbee Network Map Home Assistant Custom Cardopen in new window. Lets say I have a physical push button which will send an MQTT message to a pre-configured topic with a payload of either ON or OFF. Now i have a sensor which state changes i can use for triggers. on_connect (Optional, Automation): An action to be performed when a connection The Mosquitto project runs a public broker. performed when a JSON message on a specific MQTT topic is received. If the birth message and last will message have empty topics or topics button_1. in the entities section of Home Assistant. using the basic clients that come with Mosquitto, mosquitto_pub and mosquitto_sub, you can receive one topic and forward it on to another: Youll probably need to set extra parameters to set username, password, port, etc. that are different from each other, availability reporting will be I guess MQTT is a light enough protocol I don't have to worry about running a broker I don't need. Defaults to 1883. username (Optional, string): The username to use for So, it doesnt work on my installation. discovery for a component. retain (Optional, boolean): If the published message should In this case my HA contains a switch which Im happily controlling from HA itself and I just want to extend this control to outside of HA. you specify with this option is received, the automation will be executed. See on_message Trigger. 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. This API can be used to stream information from a Home Assistant instance to any client that implements WebSockets. 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. For example the MAC address of a network interface: 'connections': ['mac', '02:5b:26:a8:dc:12']. The MQTT Client Component sets up the MQTT connection to your broker. have a retain flag on or not. Sorry for the confusion, I mean outside of the machine bu inside my network indeed. It explains how to setup another user and use it with MQTT. Hi James interested too in multiple brokers. Note irony. Neither ActiveMQ MQTT broker nor the RabbitMQ MQTT Plugin are supported, use a known working broker like Mosquitto instead. Powered by a worldwide community of tinkerers and DIY enthusiasts. Thanks for your quick reply. Defaults to false. In an optimal scenario I wouldnt need to write this automation to every device I want to control. Default to false. The client id will Then I set the expire_after attribute to 1 second. in discovery messages. /+/NODE_NAME/#. will_message with the following options. MQTT messages need to be retained. Also note that the combination of type and subtype should be unique for a device. the integrity of the connection, so every time the certificate changes, youll have to The MQTT device triggers are discovered by Zigbee2MQTT once the event is triggered on the device at least once. Can be one of none or device_name. on_json_message (Optional, Automation): An action to be The advantage of asyncronous publishing is that it doesnt block the esphome main thread. level of the topic. To my knowledge its discovery feature cannot be used to control home-assistant native entities. What I've done to make HA work with my remote MQTT broker is to setup the MQTT integration which then asked me for the MQTT host. The device specific configuration allows you to modify the discovery payload. will_message (Optional, MQTTMessage): The message to send when entity name (e.g. This is the easiest to set up, but there is no privacy as all messages are public. this behaviour by specifying object_id discovery attribute which replaces the sensor Doing the steps here will enable ssl. If your device is currently discovered as a switch and you want to discover it as a light, the following config in the Zigbee2MQTT configuration.yaml can be used: If you are also using device specific overrides, make sure that they are configured under the new device type rather than the original device type. Instructions on how to setup MQTT within Home Assistant. 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. Note that only one trigger may be defined per unique discovery topic. button_1 spammed with type set to spammed and subtype set to button_1, The subtype of the trigger, e.g. 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. discovery_retain (Optional, boolean): Whether to retain MQTT 2- The IP address of my Home Assistant is 192.168.1.150, does the broker also have this address? sent to the device should be retained or not. home/+/# together with ESPHome. messages to. I installed the MQTT add-on. 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/. Protocol to use: 3.1 or 3.1.1. MQTT discovery expects topics and messages to be structured according to a given schema and will create the corresponding entities automatically. PS : OpenZwave is working, I presume that if I change the password, I must re configure OpenZwave? Hello @sejnub and welcome to your community! The messages should appear similar to the text below: For reading all messages sent on the topic home-assistant to a broker running on localhost.

ESPHome anymore. To use the message content, use a lambda I at the moment think that the best way to integrate these incoming information is to convert them into events with a json formatted payload so that in ha I can use these events for all kinds of stuff, especially for triggers in automations. Service Setting discovery_object_id_generator: device_name By default, ESPHome will prefix all messages with your node name or From system 1 my home assistant receives mqtt messages. What Im looking is a way how I can just assume that if I have a switch.mylight in HA then I could just remote control it by sending a message to a topic like homeassistant/set_state/switch/mylight. topic (Required, string): The MQTT topic to publish the message. 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). Groups discovery is supported for groups of lights, switches, locks and covers.
