I pulled the trigger on a 4 pack of these from ebay given I read that the support was added and working for Iris V1 devices on the C7 as of v2.20 onward, however I can ONLY get the first one to pair. It doesnt matter which of the 4 I pair first, it will always pair instantly and detect the driver and report Motion/Temp/Battery/Tamper states.
The issue is that I cannot for the life of me pair units 2, 3 and 4. Mainly it will pair as device type "device" and after linking the correct driver no states are reported.
I have tried unplugging other nearby repeaters, putting the motion sensors right next to the hub when pairing, rebooting after pairing the first unit and even using brand new batteries etc etc all to no avail.
Looks like a bug.
Does anyone have a workaround please?
