Temperature Minimum is 0.0 Degrees

[l0mp1]

My outside temperature sensor (GT-WT-02) is measuring -7.6 degrees Celsius right now. This is also displayed in the log and in the pimatic frontend. However, Eve is showing 0.0 degrees Celsius.
Temperature values seem to be displayed correctly when >= 0.0 degrees.

I hope a min temperature of -50 degrees is enough...
