Hi everybody,
this is very specific, but I cannot be the only person that needs this, so perhaps somebody here has already done it.
Does anybody have any 3D printable files (ideally modifiable ones) to create, for example, a multi-switch with ESPHome that goes inside what I believe translates to embedded pattress/junction box?
I am talking about something like this, though I would use a dual box instead of a single one (single one is pictured)
Inside there would be the ESP32 (perhaps with external antenna for better wifi coverage?), and on the outside (where you would usually mount the attached switch or outlet), there would be a base plate that fits this type of box.
In my specific case, I would like to attach 8 momentary buttons, so the “shield” would/could be larger on the outside than the mere box, as long as it mounts to it.
Why? Currently, I use many Aqara Opple Zigbee switches around the house. They support single,double,tripple press and hold, and battery life is pretty good. But it is still battery life, so eventually you’ll have to replace them. However, no wires, so yay.
However, such an ESP would be powered right inside the junction box, so no battery changing.
I assume this wouldn’t be that hard to create, but I have never designed a printable 3D object, so if somebody else has already done it, it would be nice building on top of that 
Idk. if it would be up to code to power an ESP32 from inside these boxes here in Germany, but I could imagine as long as there is a 230V-to-12V converter in there, it should be fine…? But even if not, let’s say one would have to power it from an outlet, the outlet could be right underneath this box (when using a double or even triple junction box) and the ESP could still be hidden inside the wall…
Thanks in advance for your suggestions
