MQTT -> Last Will Testament (LWT)

#1 Post by paveleremin » 30 Dec 2016, 08:20

Is the MQTT Last Will Testament (LWT) available on ESP Easy?

If yes, where it can be configured or what topic used by default?

Sort of.... listen on mqtt queue, i.e. sensors/espeasy/ESP60/status for msg.payload = "Connection Lost".

Good option could be automatic messge "Connection online" in the same topic just after device boot. Also this both messages may be published as retained. New MQTT subscriber will be able to always check of ESPeasy node.
