I've made some progress and I have MQTT messages getting received into
MQTTSubscribe and put into the weewx database file!
Here's the relevant section from the MQTTSubscribe section of weewx.conf:
*[MQTTSubscribeService]*
* enable = true*
* host = localhost*
* port = 1883*
* keepalive = 60*
* username = None*
* password = None*
* binding = loop*
* [[message_callback]]*
* type = json*
* [[[tele/AS3935/SENSOR]]]*
* [[[[Time]]]]*
* ignore = true*
* [[[[AS3935_Event]]]]*
* # Use the default variable name from MQTT*
* # MQTT messages with and event value in the following will
be ignored.*
* filter_out_message_when = 0, 2, 3, 4, 5, 6, 7, 8, 9*
* conversion_type = int*
* [[[[AS3935_Distance]]]]*
* # Use the default variable name from MQTT.*
* [[[[AS3935_Energy]]]]*
* name = lightning_energy*
* [[[[AS3935_Stage]]]]*
* ignore = true*
Here are a few lines from the /var/log/syslog showing the AS3935 messages
coming in and getting conditionally ignored.
So, we know that part is working.
*Jun 25 19:50:46 pi3 weewx[31711] DEBUG user.MQTTSubscribe: (Service)
MessageCallbackProvider data-> incoming topic: tele/AS3935/SENSOR, QOS: 0,
retain: 0, payload:
b'{"Time":"2021-06-25T19:50:46","AS3935":{"Event":0,"Distance":0,"Energy":0,"Stage":7}}'*
*Jun 25 19:50:46 pi3 weewx[31711] INFO user.MQTTSubscribe: (Service)
MessageCallbackProvider on_message_json filtered out tele/AS3935/SENSOR :
b'{"Time":"2021-06-25T19:50:46","AS3935":{"Event":0,"Distance":0,"Energy":0,"Stage":7}}'
with AS3935_Event=[0, 2, 3, 4, 5, 6, 7, 8, 9]*
Then, in the Corrections section of weewx.conf, I am using a conditional
statement to assign the AS3935 distance data to the weewx stock variable
lightning_distance.
I wasn't sure if my syntax was correct, but lightning distance data is
appearing in the weewx database, so it appears to be working.
*[StdCalibrate]*
* [[Corrections]]*
* outTemp = outTemp - 1.5*
* barometer = barometer + 1.23*
* lightning_distance = AS3935_Distance if AS3935_Event == 1 else
None*
Finally, I looked in the weewx.sdb database file and saw 3 lightning events
listed in the variables lightning_distance and lightning_energy!
See attached.
I don't have the lightning_strike_count getting accumulated, yet....have to
try and figure out which of the accumulator type to use.
Progress.....
