Well that’s a shame. I ordered one of the Sonoff switches since it sounded like they would fit in a Decora faceplate. Nope. The faceplate is integral with the buttons. So it will fit a US single-gang box, but you’re stuck with their faceplate
You can see how the faceplate actually connects to the main body
Hrm, possibly the actual faceplate might be removable ? But no, it isn’t, and there are no holes for attaching a real Decora faceplate.
Dammit.
