Hi everyone,
I just recently (1/11, 9:30 PM) updated the firmware of my uRadmonitor A3 (HW: 105)from firmware version 126 to 139 after I got it mailed to me by Radu.
I just now realize that the VOC values the device reports are now hugely different. Before I had values somewhere around 290.000 – 320.000 Ohm. With the new firmware I now see values around 4.000 – 7.000 Ohm.
See chart: https://www.uradmonitor.com/tools/dashboard-04/?open=82000095
Has anyone expierenced the same?
The flashing process looked ok and all the other sensor values look (at least to me) like sensible data.
