Follow switches HS200/v5/1.0.2 and HS220/v3/1.03 need to have controller mode to be implemented in which they will never interrupt or variate voltage, but instead, will rely on smart actions to control other devices. In case of no wifi, switches should automatically work as dumb switches. 

Thank you.

P.S. for now to implement this feature I put switch and smart bulb in 2 different power lines, so I lose a control of light in case of issues with wifi.
