Any interest in getting vibration from an MPU?

[Frogmore42]

I have some M5 Stack Atom Matrix devices. These have an MPU6886 in them. I am unclear on what anyone is doing with an MPU and Tasmota. I do know of many use cases for an MPU, just not at the sample rate/method that Tasmota presents the data. I did buy a Zigbee vibration sensor (THIRDREALITY Zigbee Vibration Sensor). Based on the data it presents; it really looks like it is using a MEMS IMU inside. It has variable sensitivity, which seems to change the amount of vibration that needs to be present to trigger the binary output that vibration is present.

I did a quick prototype to see if the idea is worth pursuing and I get some decent results. The basic idea is to quickly sample the acceleration values and look for changes (simple delta from last value in each direction).

I know that I could use an actual vibration sensor https://www.circuitbasics.com/how-to-setup-vibration-sensors-on-the-arduino/ but where's the fun in that?
