Energy monitoring is one hour off

Configuration
1

I’ve recently enabled the energy dashboard in Home Assistant, based on readings from the Tibber Pulse integration.

Looking at the usage bars in Home Assistant vs. the Tibber app; it seems like Home Assistant is one hour behind. I can’t find any configuration related to this, and don’t really understand why.

The usage matches exactly the app, only Home Assistant is behind.

Tibber app: 07:00-08:00 : 5.3 kWt
Home Assistant: 08:00-09:00 : 5.3 kWt

I’m sure that the Tibber app is right, as this matches the expected usage.

I have set timezone correct in Home Assistant.

Any ideas why this is happening? Or what I should be looking at to figure it out?

Know issue (by me): Long-term statistics: websocket "history/statistics_during_period" API · Issue #56052 · home-assistant/core · GitHub

I guess frontend didn’t fix it to use the end date, yet.

Thanks :slight_smile: I’ll open a bug for this.

You got a link to a github issue?

Did you get a solution to this?

I’m having the same problem.

Having an AMSHAN connectet

I was just bitten by this bug. I suspect it’s a case of bad interoperation (a race-condition, basically) between AMSHAN and the Energy subsystem. That is, AMSHAN is updated on the hour. And I suspect so is the Energy report. So, for example, for the period 8 to 9 o’clock AMSHAN is updated maybe at 9:00:02, and the Energy subsystem is checking the energy usage at 9:00:01, but only gets the previous data, namely the AMS data from 7 to 8 o’clock. So, while it appears the Energy report is one hour off, it’s really just because it’s 1 second off.

I’m getting this same issue on my HA Energy dashboard from Solar Assistant connected to Sol-Ark. All systems appear to be on the same, correct time settings. Running latest HA updates. Has this been addressed yet?
