I have had an X10 system installed for some years now that control a set of 6 ceiling lights. Each of the mains lights are linked to an X10 dimmable controller (an LD11 DIN module mounted on a DIN rail in a cupboard; one for each of the 6 lights). Originally I controlled the lights remotely via a TM13U X10 RF receiver, though this has not been used for some years, and is no longer plugged into the system. Currently each of the 6 lights are manually controlled (turned on/off or dimmed) using a momentary push button switch, on a wall plate, that is linked to each of the LD11 modules.
Over the past 6 months or so some of the lights randomly turn on or off, usually late at night, and I am trying to figure out why. It is not always the same light (so it is not linked to only one of the LD11 modules).
Can anybody suggest what might be causing the problem?
For information I am based in the UK. I do not have an electrical smart meter installed, though I do use both wifi and a homeplug system for distributing broadband around the house - however the wifi router and homeplugs that I am using predate the issue I am having with the lights.
Could it be a problem with aging of the LD11 modules (they are about 10 years old now); my broadband causing interference; or some new electrical spiking of the mains supply?Or something else??
Any suggestions as to how I can determine the source of the issue and rectify it would be appreciated.
Many thanks
