Hello - I’ve got a more basic problem, see here: Mosquitto - no data seen in logs (but can log in) - i.e., I cannot see the json data coming into HA.
Actually, using the listener, I can see the data. Integrations/MQTT->configure, Listen to a topic, Listen to “#” and 'start listening.
The state topic is ‘enviro/enviro-u01’, where the 2nd bit of this is the name I provided when configuring.
Thank you to previous posters in this thread - this has helped me!
