Unrealistic temperatures

[slundell]

The temperatures read from PGN 130312 are sometimes unrealistic. These temperatures seems to be fixed around -272.3C and +380.8C. I do not know the source of the errors. Maybe they are wrongly reported by the NMEA2000 device. Maybe the issue is in the conversion calculation in this addon? How do I debug this issue?

Soes rhe rest of your N2K report ok? What is the device? This PGN reports in Kelvin and the integration performs an additional conversion to C. Is the Kelvin temperatures wrong as well?

It seems to me that there are problems parsing the hex output. There is a ":" in there. Maybe the hex string is cut in the wrong place but is parsable.

There are these extreme values in data from other devices as well. I get these errors in the log.

I have looked through most of my data and noticed this error in almost all numbers. The only one not showing this is PGN 127257: roll. The ones below all have extreme values like 1300 knots of speed for instance :)

PGN: measurements with intermittent errors 127257: pitch and yaw, all units. Not roll 130312: Actual temperature, all units 129025: both lat and long 128267: Depth and offset 129026: Both COG and SOG 129029: Altitude, lat, long number of SVs

Snippet of the debug log. I do seem to have a few read errors on my network, which might be the root cause. It would be better if smart2000usb ignored malformed packets. In this instance the last part (after the ':' is empty)

Ok..There is something weird going on because those pgns normally work. Can you set the log level to debug for the integration. Restart HA. Collect 15 mins of logs. Enail them to me at smart.boat.innovations@gmail.com

[SmartBoatInnovations]

With these error the processing for the pgn is aborted and the sensor is not updated. I do not think this is the cause of extreme values. In the 15 mins of log I could only find 1 of these anyway.
