Hi there amazing thread! Hoping to get some guidance on my setup.
- Fujitsu AUU7RLF ceiling cassette with UTY-RNNUM wired wall controller
- Purpose-built ESP32-C3 + LIN transceiver board ("Fuji_LG_Lino_Uarto_Mod2.0", thank you nathansags!), wired in parallel to the UTY-RNNUM's 3-wire (Red/Black/White = 12V/GND/LBUS) terminals
- controller_address: 1 (secondary), UTY-RNNUM DIP switch 1 (Dual remote controller) = ON, switch 2 (Master/Slave) = OFF (UTY-RNNUM stays master)
When I power up, seems fine for ~75 seconds, Home Assistant sees it fine, then I get a flashing "Er 12". I am just using the yaml that nathansags. I am including both that and the (truncated) logs below where you can see when the error hits.
Anyone out there have any ideas of have I might be able to get this working? Sorry in advance if the answer is clear as day in this thread and I somehow missed it!

PS @rogerjet this looks a lot like your issue above, did you ever find the answer?
