The behaviour for the Fibaro Single Switch 2 FGS-213 is not fully correct.
For S2, I’m seeing the following behaviour:
Toggle switch state changed
“Button pushed” shows on device in app, in either direction (requires modification to pushed/held)
Power On / Off toggled in app (incorrect)
DOES NOT control the local load (correct)
Routine for “Button pushed” works. (correct)
If the S1 load is physically on
Physical S2 toggle does not change state of load (correct)
Does change power state in app (incorrect)
This is in-line with the “Toggle switch synced with switch status”, so if S1 is on & S2 is off, then S2 toggle switch is changed to on the power indicator stays on. If S1 is on & S2 is on & the toggle switch is changed to off, the power indicator will go off. (The actual load output does not change).
If the power button is pushed for the device in-app, this controls the local load (correct) and changes the power state (correct). It does not activate the S2 scene/button (correct).
In the app’s device history, the Button press & Power state is logged as per the above. The power meter will only log if the actual output load changes (due to the S1 toggle switch or in-app power change).
I have seen the same behaviour in the stock Z-Wave Switch Edge driver as well as @Mariano_Colmenarejo 3rd party version (in which the Fibaro Dimmer 2 behaviour is absolutely perfect with both S1 and S2 & in-app behaviour).
Let me know if you would like any CLI logs.
Thanks.
