Hi, I would like to have optimistic mode for Z-Wave the same way we have it for mqtt.
When a state_topic is not available, the switch will work in optimistic mode. In this mode, the switch will immediately change state after every command. Otherwise, the switch will wait for state confirmation from the device (message from state_topic).
This would be useful for the GE Z-Wave and other dimmers that don’t immediately report their status so the switch flips back to the previous position for a few seconds before settling in the correct position. Setting polling and refresh does not correct this behavior. The only way right now to fix this is to set Z-Wave Command Dim Rate to 1 so that the transition happens fast enough for the flip to not happen. This is not ideal though and optimistic mode may be a better method.
