and have had no problems so far in about a month. Pairing it is a bit of a fiddly process, but once done it’s fine. I’ve been using a combination of webCoRE pistons and the smart lighting smartapp to make it do what i want to do. (i’ve also ordered a couple of wall switch covers, to hopefully stop other people switching the power off)
I’ve also been using a Xiaomi cube but that has been less reliable, and the Ikea Tradfri dimmer (the small round one) which needs to be paired with smartthings and then directly with the tradfri bulbs.
