Physical Movement Alarm (Accelerometer/Gyroscope) ESPHome? Help?

I have some physical property that I want to protect and the best way I can think of is some sort of Accelerometer/Gyroscope to detect when the “things” are moved.

I was thinking of using the MPU6050 Accelerometer/Gyroscope Sensor on a ESP32.

The sensor would then feed into Home Assistant.
I would then be able to “Set the Alarm” which would do the following…

  1. Capture the current values of all axis
  2. Allow a threshold of movement (allow for wind)
  3. If the axis changes outside the threshold, trigger the alarm

I can’t think of anything else to physically attached that will alert if somebody starts ‘tampering’ with it.

Does anybody else have any other solution or a quick guide to the above (if it will do the trick)

If it has to be battery powered this Zigbee sensor should last a lot longer than trying to power an ESP.

Thanks Tom!!!

That looks quite useful.

I was thinking of using a buck(?) Converter to use a car battery (via a split charge to a leisure battery) to power the esp

I decided to get a Xiaomi Aqara Vibration Sensor but I can’t get this connected with my Samsung Smartthings using a controller. I have tried veeceeoh and bspranger but none outputs correctly.

The next thing I’m trying to find some physical hardward for is a Roof Tent. I want to somehow be alerted if the tent is tampered with. The vibration sensor would have worked, but thinking more ESPHome root now.
