Hi Floresta.
Forgot about the first part of your post. I have not been able to get the light strip to work at all unless connected directly into the plug. I have got information about the 'rayexelec' from another form (johnwasser) and apparently the 'rayexelec' could be a simple relay box ?. Not sure what the purpose of the relay box is though.
Thanks a million for your help
