Suggestion for Shed alarm

wait4me

I just want to use a Sonoff PIR and Sonoff RF bridge to alert me if somebody is in the shed. I was going to get the alarm to turn on a light or lights inside the house. Does anybody know of some sort of buzzer that could plug into a Sonoff smart pug that might sound for say 20/30 seconds and then turn off until activated again by the PIR/Bridge alarm? Could I get a Sonoff socket to turn off after a period of time after an alarm (i.e. reset itself off). Like a loop timer? Or any other suggestion?

Perhaps something like the following, hooked up to a 12V AC-DC adapter plugged into your Sonoff plug:

Another cheap option would be a Xiaomi Bridge/Siren and some Xiaomi motion sensors and door sensors of the garage.

There are also other cheap alarm systems on Amazon that might do what you need.

Get an indoor yi camera too. You can seee them and the night vision is really good

Thanks folks: I was hoping for an indoor buzzer (not a siren that would blast me out of bed :D :eek:) which I could have in the bedroom for example. I have cameras on 24-hr continuous record at the moment. I just want something to alert me if the shed door is opened partcularly at night.

Haha, then the Xiaomi bridge and sensors is worth checking out. You can adjust the volume and what noise gets played on that when the sensor is triggered.

I have a Sonoff Bridge, Sonoff PIR and Sonoff wireless door sensor. I'll mess around over the weekend.

This guy uses 433mhz like the Sonoff PIR, sensors and gateway so can be interlinked:
