Insight download incorrect

Hi,

Today I discovered that insights don’t show the correct values. If I show the last hour of energy consumption, then values of my energy consumption show as low as 180W, when showing the last 6 hours values are higher. Now I can understand that since with 6 hours, you have to cramp all the data in the chart, and since you want to show smooth lines it shows different values. But even when I download the data I get inconsistencies.

This is what I get with the hour view:

This is what I get with the last 6 hours view:

Does anyone know of a way to get the acurate data, I need data for more than an hour and I don’t want to export manually every hour. Would be great if there’s a way to specifiy a custom time range.

Feels like a bug, is there a way to report this to Athom?

I’m on a Homey Pro (Early 2023) version 12.3.1 with web app version 1.11.19

I don’t think it is a bug. Because not the measurements are stored but the points of the graphic. And as time goes by less graphic point are used, and the graphic changes, so also the points of the graphic. Which, again, are not the measurements.
So you have to build your own logger.

Thanks for clarifying that! On to building a logger :stuck_out_tongue:

As far as I understand, within the current hour, Homey stores the data points at the most detailed level (every 5 seconds).

After that, the granularity/resolution is decreased. Homey then combines several more detailed data points in a single one. I am not sure which aggregation method Homey applies (average of all values, the min/max value the first/last value, etc.).

In my case Homey uses the following resolution for data points:

  • Last hour: 5 secs
  • Last 6 hours: 1 min
  • Last 24 hours / Yesterday / Today: 5 mins
  • Last 7 days / Last week: 1 hr
  • Last 14 days: 1 hr
  • This week: 5 hrs
  • Last 31 days / Last month / This month: 6 hrs
  • Last year / This year: 6 hrs
  • Last 2 years: 7 days

Use the app Syslog, it does exports.
