I used Fibaro Dimmer Key No 2 to associate Applicance Module (HomePro). It can succesfully switch it ON and OFF in switch wall but I can’t see it transmit back the status in VeroLite. When I used the same Dimmer to associate another Fibaro 2x1.5W Relay. I switch it ON and OFF from the wall and it can immediately reflect the status back to VeraLite. Is it a known problem?
Not all devices report their status to Vera instantly (though Vera will poll each device individually, so eventually Vera will show the correct status). Fibaro switches do send an instant report whenever their state changes, but as far as I know, the Homepro switches do not (I have 2 of these, and mine do not sent state change reports).
