Netatmo data acquisition with gaps

Configuration
1

Hi, I’ve a question about Netatmo integration in Grafana. Netatmo and Grafana installation did not cause any troubles. All seems to work well but my Grafana graphs showing wierdly missing data points in the graphs.

The missing data points do not correlate with other Netatmo graphs.
It seems to me, that the data acquisition for netatmo sensors is somehow broken, since the data displayed within Home-Assistant is showing similar missing data points.
Does anyboda have an idea how to tackle this problem? Any help is very much appreciated.
Cheers, Andiroid

Here is temperature data directly within Home Assistant GUI:

Wierdly simliar gaps are visible in the graph.

As far as I can tell for Grafana it is the plot type that you chose (single datapoints instead of line). The Home Assistant graphs show no signs of the sensor going unavailable. The graph is normal for when the temperature is constant for some time. Home Assistant will not save those datapoints to conserve database size.

Edwin, that was my initial thought as well. But the gaps are sometimes over an hour and after that, the temperature is steeply falling for almost 1°C.

This is not just omitting duplicate data, this either a bug or a misconfiguration on my side? Isn’t it?

Or your Netatmo having bad communication? It isn’t reporting unavailable but it is also not getting new data. After the 1 degree drop it does drop further. It could also be the cold wind turning towards the sensor.

I recall Netatmo being reliant on cloud and only updating per 5 mins. In that time a lot can happen.

Bad communication we can as well cross out from the list. The Netatmo cloud data is showing reliable data every 5 minutes.

Here’s about the same timeframe where every data point is shown. Therefore the strong suspect the Netatmo plugin is doing something wrong.

I have this exact kind of situation going on with Netatmo for some time. In the Netatmo dashboard at their servers, it seems everything is fine, but Home Assistant keeps doing these gaps:

I tried to restart Netatmo while ago, but that doesn’t seem to help. Any hint where to look will be appreciated.

I have 3 Netatmo weather stations in 3 different locations and all of them have this bug.
The station that runs on my local network is also connected to home assistant in local via HomeKit and provides reliable reporting with NO bug.

As you can see on the graph below, the local sensor has no gap but the sensor coming from Netatmo cloud has sometimes gap and forget measurement.

So it seems that the problem come from Netatmo integration or Netatmo cloud servers that sometimes -but frequently- misses updating data.
I would say it happens approx 2-3 times a day.
