best product if you use LifeSmart® and have a ton of light's . it's surprise me all device , scene and automation shows in the hub app you can customize Any button to do anything in the app ⭐⭐⭐⭐⭐ if there more of A They deserve it A++++++++
works great giving you the ability to trigger action/automation with a single click, double click or long click. note that tuya app doesn't currently support toggle so you need to do something like sing click on and then double or long click for off. other note to put in pair mode hold the bottom left button on the four button model.
