Thanks. Saw there is option to create LWT message for the thing With the bridge/thing itself, is there an option to send birth messages? I.e., when the bridge connects for the first time to MQTT broker, can it send a birth message which can be used by broker to send updated messages about the dev…

I am happy I’m not alone in not appreciating the visual paradigm :slight_smile:. Unfortunately I used the MQTT 1.x. However perhaps it is possible tu use YAML (copy/paste?) in order to speed up the development, isn’t it? In case can you provide any example? tx
