Thanks for making this. I'm going to try to adapt it for the Sonoff T1 US (https://www.amazon.com/Sonoff-Intelligent-Control-Countdown-T1-US-1GANG/dp/B07HL22DQL/). I'll need to shrink the width a bit, but that's doable.

My only concern is that the T1 US has vent holes all around the unit, and this frame will block all the holes... I'm wondering if the T1 will overheat...? I might need to design something like this that has vent holes in it. Would you be able to share the original source file?

Thank you for your time.


Hello Jon,
the T1 EU has air vents inside.
If the T1 is mounted, then these are inside and there can be no air circulation.
My frame also does not cover any louvers, the "holes" that are on the bottom of the EU are to remove the cover.

I can gladly provide you with a file for changes.

Which file type do you need?
.f3d; .igs / .iges; .sat; .smt; .stp / .step

Best regards

Ah, interesting! Yeah, the T1 US is different in that it has vents all around switch. I wonder why... Hmmmmm...

Thanks for offering the files. I'd be happy to use whatever could be imported into Fusion360. As a curiosity, what program did you use to create this frame?



So the T1 EU has in the body, which is sunk in the wall also vents, but none of these is led to the outside.

The US version is longer than the EU version, but I have not seen in the pictures that are outside air vents.
I assume that you only have to adjust the frame to the other dimensions and then it should fit.

The heat that arises when one of the relays is turned on is delivered to the masonry / wall and is not very high.
I bought my first T1 about 1 to 2 years ago and have taken temperature measurements, the waste heat is negligible in my opinion.
I'm a systems engineer and have looked at the boards closely and the quality of the T1 can not overheat, even if they are warm. :)

I also designed the frame in Fusion 360.
Have the object for Fusion 360 attached here.
You are welcome to make a "remix" of the frame and publish it. ;)

Have a nice Day. =D

Ha ha! Yes, you're absolutely right -- the T1 US doesn't have vents on the side. I have no idea what I was thinking...! LOL 8-) Mine do stick out a bit due to the design of the connecting plate plus wall -- the house is 100+ years old, originally plaster and lath walls, but these walls have been "updated" to use 1/4" plywood, plus they are old electrical boxes that have no extra room in them (I had to grind down a bit of the plastic case of the T1 just to get it to fit into the box). Given all of the above, there is a bit of a gap between the T1 and the wall & box, but I should be able to make a trim plate that covers that area.

Thanks for the file -- I appreciate it! :-)
