Why does my Quinetic wifi dimmer keep failing?

[Plumbob]

I have installed a few QURW01 Quinetic 1 Amp WiFi Wireless Switch Receiver for Dimmer Switches in my home. Initially I had a problem with one low voltage (12v) ceiling light which turned out to be caused by exceeding the 1Amp maximum load, so I'm familiar with that limit. Recently, I installed another such unit to control 2 fittings each housing a


Philips 18W MASTER LED Bulb (100W Replacement) Warm White, Dimmable, E27 Edison Screw . So far, two units have failed with the same symptoms as previously experienced when I exceeded the 1 Amp max - i.e. permanently on and no response to the switch or kinetic app. Each bulb is rated at only 97milli amps, so I don't understand why the controllers keep failing.

Has anyone else experienced similiar problems with Quinetic controllers, or have insight into why they keep failing?

Is it an issue with transformer surge as it powers up?
Also some dimming methods can cause nasty back emf from transformer coils.

Are you using their kit.
(their 1 amp figure may be optimistic)
Quinetic Dimmer Switches must only be used with R301 or RW01 wireless dimming controller.

That would be my guess. The Philips bulbs are monsters, so maybe I'll try something a little bit more lightweight. Unfortunately, I need at least 100w equivalents because of the lamp shades.

Yes, everything is Quinetic, and matched. I'm thinking a surge on power up is favourite. Under normal operation the two bulbs should be drawing less than 200mA, well short of the 1 Amp limit.

This is a problem I have also experienced. Using the matched quinetic switch and dimmer receiver I had problems with the luminaires dimming at random, refusing to dim or brighten, and sometimes just not working at all. I raised a query with the supplier who in turn raised it with the manufacturer, and I was advised that the quinetic gear is not 100% compatible with all lighting equipment, even though it would appear to be, on paper. It works well with some gear, not with other stuff. As I am a fan of quinetic stuff, I simply took the dimmable stuff out and replaced it with non-dimmable, and the supplier took back the gear that didn't work. I think it's just a case of hit or miss, unfortunately, but no doubt work will be done to sort this incompatibility.
