Zero (0) values in graph

[tne7laa]

I'm using the ToonAPILib to get power consumption etc from Toon (Netherlands). It is working fine some years now.
The problem i'm having is that the graph shows 0 values in the graph. So the line drops (each 35minutes or so). See picture:



If i'm looking in the logging it show no values like that:

Code: Select all

Only thing what I see is that the graph gives graph info about values (when you hover above graph) on each 5 minutes (e.g. 10.05, 10.10, 10.15...) and the timestamps in logging are about 6 minutes from each other. Don't know if that is the problem because other graphs from other devices don't have this.

Hope someone knows how to fix this...

I solved it myself eventually. Problem was that Domoticz shows values in 5 minutes interval. The ToonAPIlib values where some time logged after 6 minutes. So then sometimes the value stays the same and because the values are shown as difference (current-previous) it wil generate 0.
Solution is to get ToonAPIlib values before 5 minutes.

Code: Select all

sudo nano /usr/local/lib/python3.7/dist-packages/toonapilib/configuration.py

change default 300 (5 minutes) to e.g. 240 (4 minutes):

Code: Select all

STATE_CACHING_SECONDS = 240

Graph has no 0 values


Hope this helps also others.

Thank you, this just solved my problem.
