My Airnote configuration is set for a sampling frequency of 15 minutes, but during the last couple of days the data points shown in the dashboard panels appear at very irregular intervals, sometimes at about 8 hours distance from each other. See attached screen capture.
Is this something related to my device (in this case, what can I do?), or is it a problem with Grafana?
Thank you very much and best regards.
Alberto
Alberto,
The sample rate gets lower related to the battery charge. This is done by design.
If you charge the unit up, the sample rate goes back to 15min.

OK, thanks for the explaination, Rob!
In fact the battery voltage was at 3.5 V. I suppose it’s considered to be the lower limit for a Li-Po cell.
Cheers,
Alberto
Aberto,
You can set up the reporting and triggers for of the lipo battery with the {"req":"hub.set","mode":"periodic","align":true,"inbound":10080,"voutbound":"usb:60;high:1440;normal:1440;low:10080;0"} command. Please refer to documentation at Notecard Walkthrough - Blues Wireless Developers

Thanks again Rob for your kind help.
I’m not a software guy, so I’ll have to read very carefully this document: I could easily mess up everything…
