Rules: Trigger Event with MQTT Subscriptions Support subscribe/unsubscribe MQTT topics and trigger specified event with the subscribed MQTT topic. You can subscribe a MQTT topic and assign an event name. Once we received subscribed MQTT message, an event will be automatically triggered. So you can set up a rule with "ON EVENT#<event_name> DO ..." to do whatever you want based on this MQTT message. The payload is passed as a parameter once the event been triggered. If the payload is in JSON format, you are able to get the value of specified key as parameter. For example, if you have a Tasmota based thermostat and multiple temperature sensors in different place, usually you have to set up a centre home automation system like Domoticz to control the thermostat. Right now, with this new feature, you can write a rule to do this. Two new commands in Rules: 1. Subscribe Subscribe a MQTT topic (with or without key) and assign an event name to it. Command format: Subscribe [<event_name>, <topic> [, <key>]] This command will subscribe a <topic> and give it an event name <event_name>. The optional parameter <key> is for parse the specified key/value from MQTT message payload with JSON format. In order to parse value from two level JSON data, you can use one dot (".") to split the key into two section. Subscribe command without any parameter will list all topics currently subscribed. 2. Unsubscribe Unsubscribe specified MQTT event. Command format: Unsubscribe [<event_name>] Unsubscribe a topic subscribed by specify the event name. If no event specified, Unsubscribe all topics subscribed. Examples: 1. Subscribe BkLight, Tasmota/BackyardLight/stat/POWER And define a rule like: Rule1 on event#BkLight=ON do ruletimer4 60 endon 2. Subscribe DnTemp, Tasmota/RoomSensor1/stat/SENSOR, DS18B20.Temperature Define a rule to deal with the MQTT message like {"Time":"2017-02-16T10:13:52", "DS18B20":{"Temperature":20.6}} Rule1 ON EVENT#DnTemp>=21 DO ...
