@TomerFi , @thecode
I'll be happy to help with this PR if code changes are required, to push this further. We need this for creating automations in HA :)

Please consider adding some test cases for the new service.
Here are the test cases for the existing set_auto_off service.

Is it possible to add multiple switcher devices in with this update (a much requested feature) ?
If not, please consider adding it.
