I have three dimmable light controllers for the back room of my house:
- Kitchen downlighters
- Dining room downlighters
- Dining room pendant
All three have their own momentary switch in a single-gang faceplate, though I generally use voice commands via my Echo Show.
My partner, though, has great difficulty getting any of the four Echo devices in the house to understand any commands... and my seven-year-old granddaughter cannot reach the switches... Enter my Flic 2!
I have a Flic set low enough for the granddaughter to easily reach. A single click turns on all three sets of lights and double turns off all three sets of lights.
The granddaughter has no problem, though my partner still yells and swears at Alexa!
