A while back, Pierre was kind enough to send me a Kaku/Coco (aka Lightwave) controller and three on/off/dimmer (power socket) switches - all EURO plugs - so I could check if they followed the same spec as Lightwave (they do!)
I’m no longer using them, so would anyone like them? Free of charge, but you pay the postage
The controller has the power supply - and as mentioned, they follow LWRF protocol - in fact when I added a device to CoCo, it showed up under Lightwave and I could control them via one controller.
Let me know
