Now that IKEA is shipping again, I ordered 4 more of their smart blinds for the living room. Received them last week. Pairing was easy because I had done it before.
Once everything was up and running, I wondered if each blind HAD to use the repeater included with the blind.
These take a bit of room and all 4 monopolize my 6 outlet wall mounted surge protector.
That involved removing the blinds from the app, repairing them and only using one repeater All 4 blinds paired just as easily with dedicated repeaters or sharing a repeater with 3 other blinds. SmartThings controlled them fine.
The only caveat is the battery reports 0% for 3 of the 4 blinds. The only blind reporting correctly is the first one I paired.
My assumption is the purpose of the repeater is to report battery level and nothing else.
