Reference: https://github.com/weewx/weewx/wiki/Accumulators
1. It says that lightning_strike_count is one of the default accumulator
variables, so I believe that means I do NOT need to declare it in an
[Accumulators] section of weewx.conf?
2. Where do I put the code that alerts WeeWX that a lightning strike
occurred?
In the [MQTTSubscribeService] section of the weewx.conf file?
3. How do I tell WeeWX that a lightning strike has occurred?
Set lightning_strike_count =1 and let the accumulator function add 1 to the
total for me?
Like this?
[MQTTSubscribeService]
[[[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
* lightning_strike_count = 1*
[[[[AS3935_Distance]]]]
# Use the default variable name from MQTT.
[[[[AS3935_Energy]]]]
name = lightning_energy
[[[[AS3935_Stage]]]]
ignore = true
