RFX chart weather graphs not working

[John]

I'm using RFX charts to display and graph the measurements from my oregon scientific sensors.
Since a couple of days only the dashboard is working but it is not possible to grap the hourly and daily graphs.

The values for the graps are correctly written down in the database and the other RFX charts functionality is working correctly.

Currently I did not a new install of RFX charts? Has anybody a hint what the problem is?

Did you ever see the weather charts?

Is there an error message in the HS log?

[John]

The weather charts were visible till this problem occured.

No errors relating to this in the HS log. Some scratchpad errors for the 1-wire devices (RFXSensor).

Restarting Homeseer after running perfectly for 172 consecutive days solved the problem.

scratchpad error can occur on the RFXSensor can occur due to battery low or a communication error on the 1-Wire connection in case you have external sensors connected. If this happens very often you can test with a 4k7 resistor between Vdd and DQ at the end of the 1-wire cable and check if the errors disappear.
