PiJuice Zero Telemetry Data Remains Constant

[baqwas]

A newbie here! Will gladly RTM if you can tell me which one!!

Quick question, please:

I've been using the Python interface to log some values from a PiJuice Zero (on a newly acquired 02W after waiting for nearly 2 years!). The readings do not change using the PiSupply 1200 mAH battery based on 48 hours worth of observations:

• batteryCharge 87
• batteryVoltage 4171
• batteryTemperature 25
• ioVoltage 5070
• ioCurrent 580 (sometimes 570)

There is no active workload on the RPi02W (Bullseye with all updates applied) but I would expect that the batteryCharge should saturate to a higher value? Also, the temperature is relatively constant. Others temperature sensors in the room do change ever so lightly throughout the day but the PiJuice numbers stays constant.

The Python script is the simplest call to the corresponding functions as derived from code snippets in the test examples in this repository.

Of course, I may be extrapolating to an erroneous conclusion here by drawing on my UPS telemetry experience but I hope that someone can help me understand which parameters should be monitored (apart from the status). Thanks.

Kind regards.

Can you run pijuice_cli? If so, please provide a screenshot of the status page:

Thanks, @tvoverbeek! The ioCurrent changes by two decimal places and the ioVoltage only occasionally by the last digit. Makes sense since there is hardly any load. Everything else remains constant. Also, perhaps I'm misunderstanding the batteryTemperature value. Perhaps I was too hasty.

Regards.
