Hi @flub1dub, this appears to have been an incorrect downgrade done by our systems. We have corrected the issue by downgrading the appropriate channel, and your device should now report correct readings. However, it will remain transparent to indicate that a channel has been downgraded.
Your device has two laser counters that conduct independent measurements. These are referred to as “Channel A” and “Channel B”. Channel B for your device is reading correctly as seen in the map graph. However, Channel A appears to be reading only zero. If you hover your mouse near the bottom of the graph you’ll see the data for Channel A highlighted.
If a channel isn’t reporting correct data, it can be “downgraded” by us to prevent the bad data from showing on the map. In this case, Channel B was downgraded by our systems when Channel A was the one producing bad data by reporting all zeros.
The zero readings are likely due to a broken fan, but could also be caused by debris. For information on cleaning your device, we recommend you take a look at our sensor maintenance article. If cleaning does not resolve the issue, your device may need replacement laser counters.
If Channel A begins to read correctly again, please contact us and we can remove the downgrade.
