We have not yet been able to reproduce this issue on our side. From the logs, this does not appear to be a hardware failure. Instead, the Pironman 5 Dashboard’s Data Logger fails when trying to read the CPU frequency in the Home Assistant OS (HAOS) environment, resulting in a NoneType error.

To rule out the possibility of a faulty add‑on installation, we recommend that you first uninstall and reinstall the Pironman 5 add‑on, and then observe whether the error still occurs.

At the same time, please check whether the basic functions of the Pironman 5 (such as the fan, OLED display, and RGB LEDs) are working normally.

If the issue persists after reinstalling the add‑on, please let us know and we will continue to help you investigate. We will also share your case with our R&D team for further analysis.

Thank you for your patience and cooperation.

Thanks for info. I uninstall addon, reboot the system and reinstall but same errormessage appear. But i notised that OLED-screen not working properly (all letters and numbers are scranbled). Could fhis cause this problem ?

If the OLED is not displaying properly, that is not normal. Could you please confirm whether you have completed the “Install the Pi Config Wizard Add-on” step as described in our documentation, and restarted Home Assistant twice as required?

This is important because I2C and SPI need to be enabled, and the changes only take full effect after two reboots. If this step was not completed, the OLED may not work correctly.

However, we believe the OLED display issue and the Data Logger error are two separate problems. The OLED not working should not cause the Data Logger to stop.

Please confirm whether you have completed the Pi Config Wizard configuration and the two restarts. If you have, let us know and we will continue to help you troubleshoot the Data Logger issue.
