I have one of these controllers and thanks to @steveff - it was wired correctly now.
I just updated my hue hub (should I not be doing that?) and now the controller is saying "unreachable". I removed it from HE and then Hue and re-added it to hue, but after a few seconds it goes unreachable again.
I reached out to Kevin and he said that the controller is Zigbee 3.0 (ZHA and ZLL) I dont want to add this to my HE if its ZLL and gives me grief.
So im not sure my options, buy an Ikea repeater and pair that between the controller and the Hue - or try and connect it straight to my HE and wait and see if it causes any issues.
Anyone have any experience they can share with these devices ?
