[Home Assistant] some topics fail discovery about p1p2mqtt HOT 9 CLOSED

Hi @fishbone-git, indeed it is the MQTT buffer size, please upgrade to 0.9.18 or newer which increases this (HA_VALUE_LEN) from 300 to 600 to resolve this issue.

The buffer problem appears solved, but there is a new problem. I'm using HA 2022.9.0b4. All topics appear in MQTT broker, and in th discovery topic. HA is having a problem with a number of them, and so they are no longer available entities in HA after upgrading to 0.9.18. Hard to check all topics, but the ones generating the error all seem to have state_class="". I do not believe this is allowed by HA. When I manually publish a discovery topic to remove state_class="", it immediately creates an entity in HA

You're fast and fully correct! Sorry, I should have advised to jump to the newest version: 0fd7519 solves this too.

I just spotted that too :). I guess let's close this and either I'll see if I can now get a working build or wait until next binaries are published. Thx!

I'll make them available soon - was waiting for the climate and water heater integration to be finished and tested.

Not as official release, but v0.9.20 images (for E_series) are here.

from p1p2mqtt.

The images have been replaced as the ATmega OTA upgrade didn't work properly due to a BSP issue on my side. The current Eseries images should be fine.

Thanks. I'll try the images tonight and see if there is a difference. I did finally manage to get a build on arduinoIDE that seems stable
