I don't show 2 but I did get stuck installing this part way thru so deleted device, app, drivers code, & app code then started over. I have rebooted hub since a few times. The MQTT Connect Device does show present.
I just tried restarting the app by clicking thru, turned off and turning on HA MQTT Discovery protocol and even re-booted hub. Still no dice and MQTT Explorer still isn't showing homeassistant in there.
At the beginning of the log page I put in previous post, it says "MQTT> MQTT subscribing to: homie/hubitat-hub-mqtt-beta/+/+/+/set". Should that be pointing to "homeassistant" instead?
Also, can someone post their MQTT Explorer screen that shows where "homeassistant" should appear?
