I know this isn't really the right forum but, since I am 'amongst friends' ...
I want to add an additional PIR sensor to my outside lights but practicalities are such that hard-wiring it would be a major mission. I therefore hope to be able to use a battery-powered (maybe even solar-charged) PIR sensor which can communicate wirelessly with some sort of receiver, which I can use to operate a relay which interfaces with the lights. The receiver could be mains-powered, since it will be adjacent to a suitable supply, and the sensor really needs to be suitable for outside use (although I probably could 'shelter' it to some extent).
My searches have not found very much, not helped by the fact that the idiots who invent product names/descriptions very often seem to use 'wireless' to simply mean battery-powered! I've found one or two expensive ones designed to interface with specific alarm systems (hence without an explicit 'receiver'), but not much more than that.
I may end up having to adapt something like a (really!) wireless PIR 'door chime' or something like that, but I can't help but think that maybe the wheel I'm looking for has already been invented. Is anyone aware of any such animal, or something close to it. I'm happy to play with the interface electronics at the 'receiver' end if I have to.
Thanks for any suggestions.
Kind Regards, John
