Battery rate 120.0% per day yet battery not changing much

[simonmason]

Hi, I have a device Aeon Labs Sensor that is showing a high discharge rate when in fact the battery level is hovering around the same level. Any thoughts on this? Thanks.

Sorry - forgot to mention - using version 3.0.7.5.

What that indicates is that you have a device which is reporting 2 different battery levels very close together. In your partial screenshot there are 11 readings all on the same day and they are fluctuating between 70% and 69%. Unless you are rapidly polling the device for battery levels there is something a bit odd about the device if it is sending out so many readings close together.

If you look at the SDJ-Health tab for the monitoring device you can see the full battery history and it shows the times as well as the days. If the device reports a level of 70% and then 12 minutes later reports a level of 69% then the instantaneous discharge rate is 1% in 12 minutes i.e. 120% per day.

If you turn on 'Show Average Discharge Rate' you will get some further information displayed which is a bit more informative. However, discharge rates are never going to be very useful for a device that is reporting like the one you are showing. Make sure you have alerting on discharge rates turned off for that device as the alerts will be useless.

Refer to page 9 of the guide where battery discharge rates are described in more detail.



I hope that helps.

Thanks, I wasn't paying attention to this. I twas thinking overall discharge, not discharge rate.

The device in question is an Aeon Labs multi-sensor, an older series. I only have a few and they have mostly worked for me but I do see lots of posts with people having issues with them.

I had it in another room but had to replace it because it was misbehaving - mostly because I was losing the connection to it as it was the outermost node on the mesh (I think). So I moved it to a more central location and it stayed connected.

Looking at the log it seems like it is reporting battery levels every time the motion sensor is triggered, so I am going to start by checking to see how it is configured and perhaps reducing the reporting interval. It does seem to be stuck between the two battery levels.
