If you expect people to understand what you are trying to accomplice, then please follow the Guide-lines(to some extend) stated in first Topic
How to help us help you - or How to ask a good question.
Right, thou it doesn’t help me understand what you have ( in front of you ! )
Maybe it’s your template-sensor you have to focus upon( Is it a total_increase sensor, or isn’t it ? , does it ever throw “exceptions” due to this “obvious” not_in_sync updates calculation of a bunch of various sensors ? , compared to your Total_Increasing_Total_Consumption_Of_House_Sensor ? )
Don’t tell me you see that “sabertooth line” in the Statistic_Card, And The Error you refers to, comes from ( Which Card ) ?
PS: I Noticed you’ve not been long in the Forum, and maybe not have had your HA for long either, But various Entities Don’t updates “syncronically” , various templates neither, And therefore your Total-House-Consumption either. ( and Is your Total-House-Consumption a “realtime” Sensor, or provided from your grid-provider(next day), with the “hickups” that implies ? )
