Hello fellow weewx-users, I am happily running weewx in combination with a Davis Vantage Vue station since 2018.
Recently, the humidity sensor of my station has developed a problem in which it sometimes report 'sane' values and sometimes it reports a 0 or 1% relative humidity. This of course results in very wonky dewpoint calculations and so I set out to fix it. Replacement sensors are no longer available, soldering a new sensor in the station is not an option. I don't want to replace the complete sensor suite in the outdoor unit as all other sensors are still working fine. I opted to setup a new relative humidity sensor. I attached a Bosch BME280 sensor to the Luftdaten air quality sensor that I have running near the weather station to measure valid relative humidity values. I am pulling the BME280 relative humidity sensor values via Home Assistant from the Luftdaten sensor and I am posting it to an MQTT broker. WeeWX reads the relative humidity sensor values from the BME280 using the MQTTSubscribeService. The new relative humidity sensor value are reported in the extraHumid1 sensor in WeeWX. This is all working as expected. The question I have: is there a way to override the standard 'outHumidity' readings that come from the LOOP packets that are read from the Vantage station with the valid readings from the extraHumid1 sensor? I tried using the [StdCalibrate] > [[Corrections]] setting in the configuration but the problem is that the LOOP packets from the Vantage station with the invalid relative humidity readings are much more frequently received than the updates from the MQTT service that only updates the sensor value every 2 minutes. So the override with the corrections only happens when a new MQTT message is received, all the other intermediate loop pakets still contain the invalid relative humidity readings from the Vantage driver (the 'outHumidity' sensor). I searched the documentation but I did not find a way to implement what I try to do. Does somebody have a pointer that I can follow to solve this issue? For your reference: my weather data with the invalid and the valid relative humidity sensor can be found on http://weer.lika.be Thanks in advance, Lieven. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
