Let’s make it work. Default is 0 and will also be used to publishing messages. During normal operation, if the MQTT sensor device goes offline (i.e., publishes payload_not_available to an availability topic), Home Assistant will display the binary sensor as unavailable. Must not be used together with availability_topic. The string that represents the off state. To enable this switch in your installation, add the following to your configuration.yaml file: A list of MQTT topics subscribed to receive availability (online/offline) updates. Description: Add configurable availability payload Breaking change: To enable support for Sonoff Tasmoto the command and availability payload are now no longer linked. This is an example of a configuration where the state is extracted from a JSON formatted MQTT message. Remove this option when ‘payload_on’ and ‘payload_off’ are sufficient to match your payloads (i.e no pre-processing of original message is required). Normally the Sonoff switches don’t support MQTT but you can buy flashed devices that run the Tasmota firmware that does.. A configuration for a “Controller” for MQTT with the protocol “OpenHAB MQTT” is present and the entries (“Controller Subscribe:” and “Controller Publish:”) are adjusted to match your needs. If two sensors have the same unique ID, Home Assistant will raise an exception. If these messages are published with the retain flag set, the binary sensor will receive an instant update after subscription and Home Assistant will display the correct availability state of the binary sensor when Home Assistant starts up. To determine the switches’s state result of this template will be compared to state_on and state_off. With MQTT discovery no user interaction or configuration file editing is needed to add new devices in Home Assistant.
