Yes it is possible with the hardware, there is separate commands for reading the status of the relays.
Problem is that I don’t know much aboout Lua coding, and I really need to dig into it.
For the time beeing my little project of using the relays for driving the actuators for my waterbased underfloor heating works quite well, and I will monitor it closely thru the cold season coming up now.
Don’t be surprised if I update it with status, but again don’t hold your breath
