so now that i am thinking about it more. i think i have identified the issue. i just need a better way to resolve it.
I think what is happening, is when i close the door to the dryer, it triggers it as active for a split second. then it sits inactive for 10 minutes and then it sends the notification.
I think what i need is a trigger (which i think id have to do through rule machine) that says if the sensor is active for X # of minutes (to indicate it is drying my clothes), and then it sits inactive for X # of minutes, then send the notification. i think this would eliminate the false notifications im seeing.
Have you considered Better Laundry Monitor? It looks like it contains logic for watching for multiple vibration sensor events before declaring the drying done.
I just use Better Laundry Monitor for the washer part, although I'm intrigued by the concept of using a vibration sensor. Did you just attach it to the exterior of the dryer? I was thinking to be sensitive enough to trigger that way, it might also trigger when the behemoth washer is on spin, which makes the dryer vibrate a little.
Yes I did, just using the magnet of the sensor itself. I am settings this up as well after my HEM is giving me fits with node-red and hub connect. Yes the washer does set it off.
To fix the "makes dryer vibrate a little" and I'm going to add a timer like Bruce mentions. The washer does spin my dryer a limited amount of time but not for as long as the dryer spins while drying,, so something like...
If sensor "accelerates" for more than 45 minutes and then stops - send "dryer's done"
