Hope I'm in the right section here

We've installed a Lighwave RF dimmer switch for our lounge lights (ceiling unit with 3x60W incandescent bulbs) but it works very, very slowly and sometimes not at all. When it does work it still doesn't get to the low level reached by the Siemens switch it's replacing. It crossed my mind it might be a clash of wifi channels. We have a BT Homehub 5 and a couple of Devolo mains-plug wifi extenders in the house.

I've not been able to find any info on the Lightwave site about what channel the Lightwave uses, so I don't even know if I'm thinking along the right lines...

I don't want to complain about a faulty device only to find it's an operator error, so any advice would be appreciated.

The dimmers use 433MHz (specs are in the manual) which is well away from the 2.4 or 5GHz used by WiFi so no chance of it clashing with any WiFi kit you or your neighbours are using.

Are you using the Lightwave remote controller or the Smartphone app to control the dimmer? It could be something blocking the signal or if you are using the Smartphone app your phone might not be totally compatible.

Or of course it is simply faulty. In which case if it is brand new simply remove it and take it back to where you bought it from.

Are you using it on an angle? If so, try operating it from a few feet away but pointing it directly at the sensor to check it's not faulty, we have a couple of these and they are tempremental if you point the remote at the sensor at acute angles.

chrisjr: Glad we can take wifi out of the equation No smartphone involved, just the Lightwave remote.

Deacon1972: You could have a point there - we'll try your suggestion and see how it goes. And we'll have another look through the instructions in case we've missed or misunderstood something.

Many thanks to you both for your responses.

We could do with a 'cheers' smilie on here...

Indeed these things don't use wifi and the radio frequencies they do use are far removed so interference won't be an issue.

One thing though, they don't actually have a 'sensor' as such, the receiver is a length of wire inside them. One thing you might try is to change the batteries in the remote control, if you purchased it at the same time as the dimmer switch. It's quite common for the remotes to ship with batteries which have been in the device for some time, they can still have enough to light up the LED on the remote (which makes you think they are OK) but don't provide enough power to properly run the transmitter.
