I think it would be great if you could design a small esp8266-based switch module, possibly versions with dimmer as well, that can be installed in existing in-wall switches for EU/US standards. This way you can keep the existing light switch for manual control but add the possibility to remotely control the light switch via WiFi.
Similar modules are available today for z-wave and other wireless standards, this is an example of such a product:
This would be great! I would probably place one behind every light switch in my home. Unfortunately the sonoff touch doesn't look good in some rooms...
Deepesh Golani, your method require change all common switch. Is it possible to run sonoff wifi switch while existing light switch is remain? Is there anyway make use of GPiO and Gnd pin?
ITEAD, any news regarding a in-wall sonoff? :)
+1 LED dimmer to fit inside EU sockets! :)
