“This is a great switch is you are only controlling via the app. However if you are also using the Manila switch input it misses the input approx 1 time in 50. It doesn’t sound like much but it gets really annoying.
Fibaro support has been fairly good and I have worked with them to isolate the issue, b it after 6 months the firmware fix has not been released.”
“Overall I have many units of this item, bought and installed behind the mains wall switches.
All bed rooms for controlling ceiling fans and ceiling lights, garden lights, mosquito trap, entrance and main door light, as well as garden electric water faucet to control watering.
Simple unit, yet requires attention not to use with hi voltage LED lights.”
“Works well but can "flip" its On/Off setting versus the wall switch state. Easily righted but annoying. The Dimmer and Single switch work more reliably.
Had in use over a year.”
“Both items Worked As Expected, Perfect, the new Walli switch took a little bit of figuring out to get it into a standard UK Wall Back Box but it wasn’t too much trouble, will be buying more”
