small Shelly 4-button box (with and without battery)

Here are two variations of my 'Shelly 4-gang button box' (z-wave), in a 'pocket-sized format'

The smaller box is powered via its USB-C port and must therefore remain permanently connected to the mains to function. The larger box is battery-powered. The USB-C port is used exclusively for charging the battery. I used the CyberBrick battery and replaced the connectors with USB-C plugs. The battery lasts approximately 16 hours in my version with the LED switch

Z-Wave has a range of up to 1.6 km in Europe and up to 2 km in the USA

The Shelly is a 'Wave i4 DC' and simply 'clips in'

All buttons are 12 mm in diameter. You can, of course, decide for yourself if and where to use buttons/switches with LEDs

The lid is simply pressed in and can optionally be secured with a few dots of adhesive
