I'm starting to add some "smart" devices to the families house. This is one design iteration for a case that can contain some multi clamps, a 220V -> 12V converter (I'm using 1A USB power connecters for this), a single channel relay and a WEMOS D1 mini (perhaps a NodMCU)
The design is straight forward, no fancy mounts or places for screws, because I'm using parts that I already have. So relays, clamps and converter might change from build to build. Just hot glue in the components and snap the case together.

If you're interested in this one, you might want to check these, too:
