Annoying issues with IKEA sockets and Hue. A couple of things were dropping out with Hue and the recommendation seems to be to try and change channels. Did that and now the IKEA sockets are no longer reachable and don't seem to want to be added again.
Thought I'd try and add them under Home Assistant instead (zigbee2mqtt) but there doesn't seem to be an option to add stuff, looks like things are just meant to show up there when they're in discovery mode but the sockets don't.
Also, IKEA stuff connected to Hue seems to be showing up in my Alexa devices twice now. Once as Hue and once as IKEA which fucks stuff up.
