Unable to decode MQTT message

[stan69b]

I have been having trouble as well and downloaded an mqtt explorer. turns out devices NEED to be detected by at least 3 eps32 , I had to bump the radius of each esp32 (via ESPresense web interface) to 16m to make sure each one covers a large part of the house and it ended up sending data on espresense/ips/#. Home assistant never picked up on it so I created a sensor and dumped the json string on its state. I use the value with HA-floorplan so i can juste JSON.parse() my way out of it.

Maybe everything is ok and home assistant just does not auto discover. make sure 3 esp32 sees your device. and check your mqtt messages with an explorer app to see if you have them popup :)

hope you wil find something that works for you

EDIT:
I also played with appDeamon configuration to get rid of the unable to decode mqtt message (well i think it was that that did the trick, but not 100% sure) :

init_commands:
  - apk add --update python3 python3-dev py3-numpy py3-scipy
python_packages:
  - numpy
  - scipy
system_packages:
  - py3-numpy
  - py3-scipy

Your AppDaemon also starts with 0 apps, I had that when i tried importing this plugin via package downloaded with the "code download" button on github. I ended up going to the release page and got a working version there.
