The thread protocol works on these lights in conjunction with the HomePod Mini abysmally. The lamps constantly lose connection, are slow to respond to settings, don't always turn off via Siri (I have to open the Home app and turn on/off the group with the lamps several times to turn them all off), the lamps in the far room don't connect at all because they are far away from the HomePod (despite the fact that there are other lamps all the way to the room that are supposed to serve as a router). Of all the smart devices I've interacted with, these lamps are the worst.
