How switches are working with the 4PM?

[jberrebi]

Hello,

I am building a new big home and planning to use a dozen Shelly Pro 4PM devices to control my switches.

Question 1: Is it possible to program the devices to fully override the switches at certain times, preventing them from turning the lights on or off? I would like this feature for Shabbat (every saturday).

Question 2 (related to Question 1): Is it possible to program the devices to automatically turn off a light if a switch is turned on?

I am not entirely sure how the switches interact with the Shelly Pro 4PM, so any clarification on this would be greatly appreciated.

Thank you very much!

question a: if you may spare an output for it, definitely yes.

question b: not clear, anyway there is the "inverse" setting, otherwise your question is not clear enough.
