Temperature at 24º C but its really at 40ºC

[jorgrde1]

Hi, I working on a Raspberry Pi 4B with a PiJuice hat on it for a month and it from one day to another the battery level get fixed at 86% and the temperature is at 24º C. I have seen in another issues that the battery problem may be solved by time, but I dont know why the temperature is fixed on 24, I used a thermometer to measure the temperature and it marks +40. Software version: 1.8 Firmware version: 1.5 OS version: Linux 5.15.76-v7

Have you tried to update the firmware to 1.6 and see if the problem persists?

Where can I find this firmware version? I have all my raspberry software up to date already, I didn't find any version of the firmware at 1.6.

During the morning today it seems that it has fixed itself, I have not done anything to the software or hardware, it has simply started to show the temperature data well and the battery has charged up to 99% like the first day I used it.

I think it could be a software bug.

From your screenshot I see you are not using the PiJuice software utilities like pijuice_gui or pijuice_cli. The 1.6 firmware is part of the 1.8 pijuice-base package. If in the pijuice_gui or pijuice_cli you go to the firmware tab it should show a newer version is available. Anyway it should be located in /usr/share/pijuice/data/firmware/[PiJuice-V1.6_2021_09_10.elf.binary See also https://github.com/PiSupply/PiJuice/tree/master/Software/Source/data/firmware

Yes, I am using the pijuice_gui, my screenshot its only a Thingsboard panel where I plot the pijuice data send by mqtt. I have already installed the 1.8 pijuice-base package and reinstalled it, doesnt appear the 1.6 firmware.

Something is wrong. If you installed pijuice-base from the Raspberry Pi repos the 1.6 firmware should be there. Here is my output of the firmware tab in pijuice_cli:

If the installed firmware is older it should prompt you to update the firmware.

Also can you run in a terminal dpkg -L pijuice-base. Here is the expected output:
