Weewx must have picked that up from a previous weather station,
reinstalling weewx without all the mqtt stuff and it is still

Jul 26 10:50:02 raspberrypi weewx[554] DEBUG weewx.drivers.ws28xx:
handleHistoryData: appending history record 1: {'dateTime': 1753541400,
'inTemp': 22.0, 'inHumidity': 56, 'outTemp': 29.799999999999997,
'outHumidity': 69, 'pressure': 1012.5, 'rain': 0.0, 'windSpeed': 0.0,

And the console shows 29.90inHg
Will let it run a while to see if anything changes.
