Help with Dryer Piston


#1

1) Give a description of the problem
It works but when I close the dryer door after emptying it triggers the piston

2) What is the expected behaviour?
Just want it to run when the dryer has finished

3) What is happening/not happening?
After emptying the dryer and closing the door the piston runs
**4)

I can’t figure out variables and the other more complicated stuff, so I would appreciate simple way to make this work.
Thanks

Since every machine is different, I would monitor the acceleration for a week (to better understand the cycles and timings), and only then, would I work on the piston.

An easy way to do this is to dump acceleration into a Fuel Stream. I am thinking something like:

(Note the extra commands are to keep the graph at 90° angles, instead of diagonal)


For the record, many sensors will pick up “activity” on a dryer, even if the door remains closed.

The piston works as it should. Dryer stops and a two minute countdown begins followed by an SMS text. Problem is I take the clothes out and when I shut the door it is not monitoring to see if there is acceleration for 5 minutes it is just immediately starting the two minute timer for the brief amount of time the accelerometer was active.
Am I using the wrong instruction on Line 21?

If you follow my advice in my previous post, you will learn that when it comes to acceleration, “active” and “inactive” are not as predictable as you may think. (IE: when the machine is running, sometimes it will show inactive… Likewise, when the machine is not running, sometimes you may get active)

Importing that piston, and letting it run for a few days will reveal more behind the scenes…


In the meantime, further analysis would require a Full log with Trace turned on.
(tips for that here)

Your first IF block:

… has zero commands, so I would not expect any action when the door closes…
(although the rest of the piston will still be processed, so the second IF may fire)

In other words, the 5 minutes on line 21 is ignored / irrelevant…
The 2 minutes on line 27 is the only time taken into account.

Ah, Thank you so much
