Bingo, fixed by installing v2.1.0-RC MQTTSubscribeDriver. Adding
collect_observations = True and single_queue = True to [[topics], I get
desired behavior. Null lightning distance is recorded in absence of
strikes and with an test simulated lightning strike by battery charger
shorting, I get
Thanks for the info. Regarding your slightly off-topic question, purpleair
and ecowitt use similar light-scattering detectors made by plantower. The
purpleair has two sensors that average out the readings and I believe are
doing some internal coding to rectify the humidity problem. The
I fear the root cause is that MQTTSubscribeDriver takes each MQTT message
and creates a loop packet. This works ok for 'aggregated' messages like
json or keyword (the original implementations). But for 'individual'
payloads that are dependent on each other, it is problematic.I've already
had
in [[Corrections]] section of weewx.conf you can do something like
pm2_5 = 0.52*pm2_5 - 0.085*outHumidity + 5.71
slightly off-topic, does anyone know if the purpleair correction applies to
other sensors, or just the purpleair?

I am using weewx-MQTTSubscribe to bring data into Weewx from sensors, so i
don't use SDR sensor map, see config for mqttsubscribe here

of unsuccessful tries to modify mqttsubscribe are commented out.

I am using the G1000 driver for Ecowitt sensors. Works fine but need to
apply a complex calculation to correct the pm2.5 sensor data.
The equation would be something like:
Cpm2.5 = (pm2.5/(1+((.25*RH)*(.25*RH))/(1-RH)))
RH = Relative Humidity
pm2.5 is raw pm2.5 data
Cpm2.5 is
I think going back to your original issue something seems to be off. Can
you post you weewx.conf for lightning data? If you're using sdr, should
contain the following in each section:
[SDR]
[[sensor_map]]
..
lightning_distance = distance..AcuriteLightningPacket
