hi kufuu, as i understand it, you are seeing values for 'pressure' on the console. the values for 'barometer' are around 31.94 and 'pressure' are around 29.9.
you said you are seeing values around 29.9 on the console. is this correct? if so, then the discrepancy is simply that the console is displaying pressure (the raw sensor readings) whereas weewx is displaying barometer (which is derived from pressure). apologies in advance for slow response to this thread, but i am racing for the next few days and will not be back to a stable computer/network until next week. m > On Jul 31, 2025, at 08:35, kufuu <[email protected]> wrote: > > Finally got the LOOP- REC > LOOP: 2025-07-31 08:31:02 EDT (1753965062) 'altimeter': > '31.994965595814566', 'appTemp': '82.21392182410236', 'barometer': > '31.943187567801353', 'cloudbase': '2960.322777616846', 'dateTime': > '1753965062', 'dewpoint': '69.84057977848587', 'ET': 'None', 'heatindex': > '75.821', 'humidex': '89.87136422415446', 'inDewpoint': '55.657507277210414', > 'inHumidity': '59', 'inTemp': '70.7', 'inTempBatteryStatus': '0', > 'maxSolarRad': '303.4440342696196', 'outHumidity': '85', 'outTemp': '74.66', > 'outTempBatteryStatus': '0', 'pressure': '29.919783335', 'rain': '0.0', > 'rainBatteryStatus': '0', 'rainRate': '0.0', 'rxCheckPercent': '100', > 'usUnits': '1', 'windBatteryStatus': '0', 'windchill': '74.66', 'windDir': > 'None', 'windGust': '0.0', 'windGustDir': 'None', 'windrun': 'None', > 'windSpeed': '0.0' > REC: 2025-07-31 08:30:00 EDT (1753965000) 'altimeter': > '31.994965595814566', 'appTemp': '82.27412271683694', 'barometer': > '31.943891983670653', 'cloudbase': '2727.7835087874173', 'dateTime': > '1753965000', 'dewpoint': '70.68375256133537', 'ET': 'None', 'heatindex': > '75.76400000000001', 'humidex': '90.44043121162365', 'inDewpoint': > '55.657507277210414', 'inHumidity': '59.0', 'inTemp': '70.7', > 'inTempBatteryStatus': '0.0', 'interval': '5.0', 'maxSolarRad': > '297.0055413107822', 'outHumidity': '88.0', 'outTemp': '74.48', > 'outTempBatteryStatus': '0.0', 'pressure': '29.919783335', 'rain': '0.0', > 'rainBatteryStatus': '0.0', 'rainRate': '0.0', 'rxCheckPercent': '100.0', > 'usUnits': '1', 'windBatteryStatus': '0.0', 'windchill': '74.48', 'windDir': > '225.0', 'windGust': '1.3421651111635826', 'windGustDir': '225.0', 'windrun': > '0.027961773149241306', 'windSpeed': '0.33554127779089565' > > > On Tuesday, July 29, 2025 at 8:37:37 PM UTC-4 kufuu wrote: > I set Debug to 2 and reran a start log, hope this helps ! > > On Monday, July 28, 2025 at 8:47:02 PM UTC-4 kufuu wrote: > On Monday, July 28, 2025 at 8:30:53 PM UTC-4 kufuu wrote: > Current Conditions ♦ > Outside Temperature 78.6°F > Heat Index 80.3°F > Wind Chill 78.6°F > Dew Point 74.6°F > Outside Humidity 88% > Barometer 31.969 inHg (0.011) > Wind 0 mph N/A ( N/A) > Rain Today 0.12 in > Rain Rate 0.00 in/h > Inside Temperature 73.9°F > Inside Humidity 57% > > > On Monday, July 28, 2025 at 8:16:29 PM UTC-4 kufuu wrote: > On Monday, July 28, 2025 at 4:46:31 PM UTC-4 Tom Keffer wrote: > Let's check what's going on in weewxd. > > 1.
