“Set one up to allow control of all hall lights in the house from a single location. Easy to do with the hub and app and it works flawlessly. No unpredictable delays like there are with WiFi/Internet based devices. Good mounting options. Tip: You can use the wall mount adapter to hold a Pico in one opening of a two-gang plate, with the other opening covering a switch in an existing wallbox. No holes in wall so it’s undoable if you’re not certain about the location. Looks exactly like there’s a wallbox behind the Pico.”
