It's better now.
The relays return to the state from before the module power supply failure, so the state in the application is correct.
Maybe it is worth adding the ability to define the behavior of relays after a power outage?
- always turn it off
- return to the state from before the disappearance
- always turn on
It seems to me that in some software I have already seen such functionality.
Ps. Can you also upgrade Supla_16x16_3NO_DOUT_16Mbit.rar ??
