I have 2 Mitsubishi, the MSZ-AP35VG, works very good with the same program, the MSZ-SF35VE2 doesn't work.

[jesus51998]

My devices is working, change the software, and push software of "github://echavet/MitsubishiCN105ESPHome" and my MSZ-SF35VE2 work very good.

Hi, I have a MFZ-KJ12NA and was having the same problem you are.

Setting the baud rate to 2400 solved the issue for me.

[JaviElio]

Same problem here. it works fine for some time, then stops and shows IDLE.
Unplug/plug the external unit returns ESP's to live.
Thanks for the info @iannnnnnnn, I'll try it
