IKEA stoftmoln 24 mounting adapter

Mounting adapter for the IKEA stoftmoln (24 cm), so it is possible to mount the lamp on to a normal Swedish house lamp outlet, socket or anything that is not a flat wall.
Lamp is great with ZigBee and connects to Home assistant. Reset the lamp by:
1. turn on
2. turn off 1s
3. turn on and off fast
4. repeat 2 - 3 5 times more. (Total 6 cycles of fast turn-ons) The last cycle (#6) shall not be turned off. The lamp will now light differently, indicating it's in pairing mode.
