Sonoff in a wall switch


It would be great if you could change the form factor of the Sonoff, so it would fit inside a European wall switch.

Something like this:

I am from US, would agree with Jeremy, if we can have single pole AC smart wall switch that fit US & EU standard switch, that would be awesome. I love to replace all my AC wall switchs with ITead smart switch if available.

Is this ESP8266 based?

Can it be reprogrammed with custom firmware?


Same queston. Is it ESP based?

I am from INDIA, would like to suggest belkin and TPlink switches types if you offer that will be great. is it possible with sonoff solution......

I think these are great ideas.  If you could 

1) Fit into a single and double gang box.  

2) Change the the relay/pcb tracks to support a 15A load since that is a fairly common branch circuit capacity in the US.  Having a 10A smart switch buried in a 15A circuit would not be a good idea and especially not code compliant

3) Make a SPDT version so that I could wire it with the existing wall switch to give smart (Sonoff) and dumb control (wall switch).

Something that could fit inside the wall and behind normal wall switches and connect to them for control would be great!

There is already an existing switch in sonoff module for manual switching. U can solder that switch with 2 wires and use a manual pulse switch( the one we use in door bells). See the picture.

Deepesh, the problem is that the current sonoff won't fit inside a normal wall switch box (at least in many European countries).

Solution to that is u take off the switch, dig a hole deep enough so that it can fit the sonoff switch.
Hi. I'm new to the sonoff products having recently purchased three. Is there a dimmer available - for led down light? I would like a day/night sensor too. Are there any other products/manufacturers compatible with the app? Thanks!
Here is a DIY solution that fits in the electrical box, it is ESP based and has manual control as well.


I have created a 3D Print design for a Decora Switch Body that accepts a Sonoff Basic.

If you find it useful shoot me a like.

Great idea.  I wish someone would manufacture those for the mass market!
