Vibration sensor: Not tripping "on" trigger?
As part of my sump pump monitoring, I have a matched pair of rules:
1) Starts shaking for 3 seconds / untrigger after 2 seconds, 125 mili-G sensitivity
2) Stops shaking for 3 seconds / untrigger after 2 seconds, 125 mili-G sensitivity
The actual shaking that I've watched happen is around 500 mG -- the pump installed today is a lot quieter and smoother-running than the old one, which ran closer to 700 mG vibrations.
Both rules set an HTTP Get to my Google Spreadsheet web app.
I have noticed that I occasionally do not get the Starts Shaking trigger before getting the Stop Shaking. That doesn't make much sense. Any suggestions for adjusting the settings?
