I just received my PIR2 motion sensor and DW1 Door sensor yesterday and quickly set it up to my Sonoff bridge. Everything was good and the DW1 sensor works well until I realised, the PIR2 motion sensor triggers off by itself even without any motion. I tried replacing the AA batteries, kept it inside an enclosed place. Still no luck to get it stop. Anyone has encounter before? or it is faulty? Below is the link to my video recording. https://youtu.be/aaDWPmlofas
Same problem here Marc, I drove myself mad changing the jumper positions, deleting and adding the PIR back to the bridge but the problem remains. It must be a hardware/firmware problem I imagine.
Precisely Dataworx22, we're speaking at the same frequency I guess. Tried for hours and hours but nothing works out. Gonna get a refund when they are back.
Two weeks ago I received 2 PIR2 sensors.
One is working well, but the other one triggers without motion.
So this is not you or your jumper settings ;)
I'll ask for a replacement.
Thanks for the heads up Awap, guess I gonna try the jumper tonight to confirm it's the hardware problem.
First (top) jumper triggers false every 15-30 seconds.
Second jumper every 3 minutes.
Third jumper : N.A.
Last 3 jumper settings are only for adjusting sensitivity and don't make a difference in false triggers.
The microswitch gives only an additional alarm pulse when released (when case is opened). No idea why they added this.
Banggood has already refunded me - very quick and professional. I've ordered some more units, I'm sure they will be okay.
BG already shipped a replacement to me. Indeed very fast and good service.
Is there a set-up PDF or Wiki which describes the jumper settings on the PIR2 sensor?
I do not have the paper based.
