We’ve recently moved house and this is on the wall outside. Can anyone tell me what this is?

looks like a cup for a security gate. Is it in a narrow gap?

Listening device

Stopper for door handle?

Baby gate mount?

EDIT Gah andyl

Looks like a sensor for a something,maybe a security light? Unscrew it and look behind it! Post a picture of the back and i can probably give you a better idea, (electrician by trade).

Limpet mine, don’t touch it!

It’s about a foot to the right of the gas meter box. I’ll unscrew it and have a look – looks more of a mount than a sensor to me.

It’s in the middle of the front wall of the house, about two foot from the ground.

haha i live in an apartment building and i have always presumed they are sensors for lights to come on in the corridors, there is one out side every apartment door, so i just took off the one outside my door and it has a small grey cable in it. inside and in my water tank cupboard is my water meter with a small grey cable going into it, the meter says “smart meter” on it so i think the water company come round and scan the black round thing and it gives them a meter reading, being so close to your gas meter i guess its for gas meter readings. so they dont have to come in your house or you have to ring them up with it.

Yep, it’s for taking water meter readings.

It has got wiring to it….

The wiring goes through the wall towards the kitchen sink area, but the units cover up where it is connected to.
Any ideas?

ahh that’s cool.

can you push the bit in the middle in, like a switch?

only cut the red wire

You’ve had the answers already… It’s a remote reader for the water meter, the meter readers have a gizmo that they offer up to your fitting an hey preto, meter read without having to come inside….

Yeah right, that’s what they want you to think. Rip it off, it the NWO bugging your house. I ripped mine off of my house now I keep on getting letters claiming to be from utilities companies trying to get into my house. The perfect cover.

You have been warned.
