How is the data fetch

10 years ago • updated by 10 years ago • 3

Is the graph only updated if the sensor data is changed? To me it seems like no sensor data is fetched for a while, but I can see that it is updated on Telldus Pro page. Is the reason that there is no difference between the old and new sensor data and then Tellmon wait until a different value is fetch before updating the graph??

Tellmon does not currently automatically update the graph. You'll need to click the sensor to make it reload data. I'm working on having it auto-update when new data arrives.

I have updated, see time and date but the graph is not updated.....

The "last update" timestamp comes from Telldus and says when your Tellstick last received a value from the sensor. A sensor will happily resend the same value every X minutes (X depends on model) even if the value has not changed.

In order to save database space Tellmon only logs new values when the actual value has changed. As you can see from this picture:

Tellmon has not logged any data for that given sensor between 13:08 and 17:05. It could mean that the sensor did not send any values or as in in this case, that the value did not change and thus the last reading is still valid. The graph component is supposed to draw the line to the end in those cases. So there is a bug in the graph somewhere.

I'll look into it.
