DIGOO DG-HOSA PIR detector 433MHZ

Any practical point of doing so? I played with them and saw code changing but that’s about it…

Also, does anybody know what this sensor emits when batteries run low?
I use OMG RF and RFLink gateways to listen to RF codes.

Want to mention that this sensor is different to SONOFF PIR2 in many ways:

  • it’s smaller and less intrusive
  • using a jumper it’s possible to turn the led off completely
  • it goes to sleep for 3 minutes when 4 or more events detected within 3 minutes

I cannot comment on its battery life as I received t only a week ago. It uses AAA instead of AA so I’d expect less time from them but it’s also depends on how many events per day it reports.

I replaced my PIR2 with this one pretty easily and it works as expected.
The reason I bought it was because one of my SONOFFs had started sending false positives after replacing its batteries (or it was just a coincidence?) That became the 4th in total that became defunct during last 2 years so I decided to give another brand a go.
