MQTT topics: LWT data

[spants]

I would like to monitor a Topic to see if a particular payload is there.
e.g. on an LWT topic, my devices publish 'online', 'offline','restarting' etc.
I would like to catch the 'offline' state.

Thanks for a great app!

Starting to analyse the payload of the MQTT messages would create a great complexity and such functionality was never intended, just to check if the messages keep on arriving or not. Therefore I am not planning to implement this, however if you do, a PR is most welcome.
