On hON ones today, no idea what could have changed.

I have looked into ESP32-S0WD-Haier/haier_climate.cpp at 2370ee2ed611f016d5c671d04a2d6bc373e7b8f3 · paveldn/ESP32-S0WD-Haier · GitHub can’t figure out why it is triggered on line 482 - how can the CRC of the received line not match.

I would really like to actually help with the dev process, but CPP is just too alien/low level to me still.

After restarting the AC it works ok, just trying to make it 100% stable.

Since I can run hON units with beeperOff it is not even big hustle to restart every week or so and after it restarts to apply mode OFF, definitely workaround, or actually even crate one more status, like error and if we get status change to error (on is valid == false) then restart the AC, so definitely work arounds are not that hard, but i’m still too perfectionist :frowning: [so that means hON or smartAir2 apps are unusable for me, OBVIOUSLY :smiley: ]
