Did upgrade yesterday from 2025.1 to 2026.4 (a long awaited update as I had to do a whole reinstall since 2 versions of rasbian passed due to libssl 1.1 to 3 breaking change) and looks there is a scale issue (mBar/Bar) in baro type chart history. See attached graph.

No other issue, except my lets encrypt certificate that would not work adding DH section (as suggested by the wiki at time of writing of my cert upgrad escript) from current pre-signed one, but still working with an oldest default server_cert.pem, saw some posts about this from 1 or 2 years ago without clues but this was IMO same issue. I'll try to look a bit more into this later.
Thanks, found it. An upgrade step in 2026.x wrongly multiplied the stored day values of Temp+Hum+Baro sensors by 10 (these sensors store plain hPa), so the history before the upgrade shows around 10200 hPa. Fixed in the next beta: a new upgrade step divides those values again, so your history is restored automatically after updating; nothing to do on your side.
