Description:

This sensor has some issue and it's being investigated on Cloud side. https://github.com/ruuvi/ruuvi.cloud.js/issues/430

Last measurement is from 6 days ago.

Sensor card showing 0C when last measurement was -19.88. User should see all last measured sensor values. History view shows correct last measurement for temp.

More details to this

The owner sees

3 sensor values on Android dashboard: Temperature, humidity, pressure

Sharee sees

1 sensor value on Android dashboard: Temperature (with incorrect reading)
Sharee sees 3 charts with correct values on history view

Currently the app is not supporting nullable temperature for the sensor. Supporting it is tricky and time consuming because in almost all of the screens and classes where we display and operate temperature we expect it to be not null. So we need to code behaviour for null temperature cases in many many places.

For now we can skip measurements that come with null temperature to avoid showing wrong value (0 C). Or postpone the changes. @markoaamunkajo

Let's postpone for now I would say. But we may need to fix this properly later.

I think not showing measurements that may not be correct somehow can just make it harder to spot issues or bugs in the future.

I assume the issue https://github.com/ruuvi/com.ruuvi.station/issues/1289 requires this discussed null support and if so, it will allow to fix also this issue.
