Anybody else getting strange values from the Dust Sensor? When first starting the system (at least after a longer power off period), I get values that seems to be normal to me. After a 2-3 hours I start to get insane high values, mostly a raw value of 1114000.62. There after I'm starting to more and more insane high values, but also several values of 0, which I can not imagine being correct either. I've a attached a screenshot of the most recent values I've got.

Our test units (about 6) of them are all running very well. Is it getting wet or clogged? Send a picture of how you have it mounted.
Run the testDust.py file and give us the results too.

Hmmm Good values spread through bad ones. This the first time we have seen this.
I'd like it back for analysis.
Please send it to:
SwitchDoc Labs RMA#081419-01 909 S Shelley Lake Lane Spokane Valley, WA 99037
We will cross ship a new one to you. Please PM us your shipping address and include the RMA# in your PM.

Sounds good. Just tell me what the value of the DustSensor is so I can fill out the export doc...
