Hi, thanks to the home-assistant community, read a lot of threads and I found my issues.
Firstly, I forgot that my relay board is 12VDC and I was powering it thought USB 5VDC so esp-01 whole whole board was working except relays was not switching.
Another issue was that not pressed S2 button. To do this I turned off relay board, removed esp01, press and hold s2 button then turn board on and hold until blue led comes red. Then I powered off the board and put esp01 back and turned on. (there might be the other manual for that but this worked for me).
This is my working config:

A couple notes:
-
This is config for 4ch relay, it controls HVAC with preheating, so there are multiple commands for each switch.
-
I am not using
optimistic: true becuase it told to home-assistant that state was changed before completed which caused a bug. I used - lambda: id(rekuperacia_on).publish_state(false); to control state change manually.
-
Reason why I am sending uart.write instead of switch.turn_on: swichname it is becuase it didn’t worked with lambda publish_state.
-
Delay between commands. Minimum which I used is 100ms, maybe lower number is possible, theoretically a couple ms should be fine, but I didn’t have time to try different settings. Please let me know what was your minimum.
