Steps to reproduce

Install DietPi Dashboard frontend on one device
Install DietPi Dashboard backend on another device
connect them via secret key

Expected behaviour

dashboard should accurately report tempature for both devices

Actual behaviour

the web UI seems to incorrectly show the temperature compared to what a locally installed frontend or cpu reports.

Extra details

In my specific case, the backend is running on native x86_64 installation on a Macbook9,1.
When first testing, running the frontend on the same device correctly reported tempature.

I guess you reported the very same on GitHub, where you closed the issue minutes after Dietpi Dashboard incorrectly report Tempature when connected to multiple · Issue #8115 · MichaIng/DietPi · GitHub

Pls stick to one platform. It doesn’t make sense to report the same topic twice.

Next, if needed report your issue to the dedicated Dashboard GitHub repository at Issues · nonnorm/DietPi-Dashboard · GitHub
