This type of problem is unfortunately not uncommon in X10
I would suspect a noise interferennce problem. Try switching off or unplugging other appliances. Are there any fluorescent lights, sometimes theycan cause interference.
You may want to try the A10 modules, I think they are soold in the UK and are supposed to be more immune to noise
By process of elimination I found that my main PC in the same room as the switch was the cause. It wasn't the monitor, hub, print server or anything else plugged into the surge protected extension lead but the base unit itself.
I have 3 other PC's in the house in different rooms that the kids use and none of these affect the x10 switch; just my PC base unit.
The annoying thing is that this is the most expensive of the PC's I have with the latest technology including modular power supply etc.
It worries me how the PC on the ring main can affect the lights on the lighting circuit. Strangely enough the x10 appliance modules on the ring main are unnaffected.
Anyway I've stuck an x10 filter on it and I'm back fully working again.
I still want to find out why the PC is creating so much conductive RFI but methinks this is going to be a painful task of swapping out components until the problem goes away. So much for the £80 modular PC power supply!
Anyway, just in case it helps anyone else in their troubleshooting.
