Remote PIR. Is there such a thing?

Homer J · 2025-01-15T09:20:30+0000

What I'd like to do is really simple. I'd like to have a PIR by the gate and a couple of spots up the wall by the roof.
Is there a system where the PIR can send a signal to a box that allows the spots to be turned on? I know this can be done using conventional wiring but this doesn't allow you to move the PIR around to find the best detection location for summer and winter.
There are many of these types of systems already but they ALL trigger an alarm / bell in the house and nothing else!

Can anyone suggest anything?

I use Philips Hue to achieve this. The outdoor PIR sensor is powered by a battery (lasts a good while) and then it turns on any configured smart lights.

The downside is obviously you need Hue gear for it to all work --- which I do have anyway. Or you can use HomeAssistant to mix and match.

The lights i need to turn on are security LED spots made by 3rd parties. Is there a box i could connect those to, to make it work with the Hue system?

You could wire a 3pin plug onto them and then plug them in via a Hue Plug.

This is how my extractor fan works in the bathroom.

Are the Hue plugs ok to go outside in a weatherproof box?

I'd say so - they are pretty small but you'd still need a big enough box to accommodate.

If you can wire the main PIR light back to a 3 pin Uk socket, and the two remote ones to a 3 pin UK socket, then you have options using smart plugs and home assistant or as dlockers said using hue setup. Smart plugs are cheap but the downside is you would need home assistant running somewhere at home on a server or something. Just saying this is an option. I use a similar setup to power up a subwoofer the other side of the lounge, when all the other gear gets turned on.

I might be mid understanding the requirements, are these any use?

Wirefree PIRs

Good shout. I forgot about the quinetic stuff. Wireless lighting control has come on now quite a bit. Their mechanical non powered switches are a game changer.

^^ this may be simpler for you, if you aren't interested in joining the Hue/smart ecosystem.

It would be hard to have home assistant running somewhere tbh. The Quinetec stuff looks better maybe.
So, would I need one of their PIRs to detect overall, and one wireless switch receiver per spotlight outside and nothing else?

There is no need to purchase Hue plugs as there are cheaper alternatives out there that are compatible with a Hue bridge...

Just found this thread, looking to do something similar to aid reversing onto the unlit driveway.
