hey tom,
for some reason i am seeing heaps of loop packets, but only a few archive
records are created from them. the loop packets are partial packets - each
loop packet contains data for a single solar panel, while the database has
columns for all solar panels. for exampler, panel 1 emits a loop packet
with p1_current, p1_voltage, p1_rssi, panel 2 emits a loop packet
p2_current, p2_voltage, p2_rssi, etc. the database has columns for 50 solar
panels (p1_voltage, p2_voltage, etc). i am currently collecting data from
40 panels.
when i run weewxd directly, i see loop data for every panel, but i see only
sporadic REC data. i would have expected to see each archive record
populated with data from all of the panels, aggregated from all of the
(partial) loop packets.
this is using the weewx-tigo driver:
https://github.com/matthewwall/weewx-tigo
operating system is debian 12
weewx 5.1 installed from debian package
configuration file 'tigo.conf' is attached
log output 'tigo.log' is attached
this is one of 9 weewx instances running on a home monitor, feeding data
into influx and mqtt, where they are used by home assistant and grafana.
the other instances monitor per-circuit power consumption, water
consumption, propane consumption, weather stations, solar production, and
battery status.
gory details: so taking it from the bottom up, we have the following:
1) i am pulling data from a TIGO CCA (cloud connect advanced) monitor using
the taptap binary to decode RS485 data from a RS485-to-usb device wired
into the 'gateway' port of the CCA (a read-only tap). the taptap
application works great - it is sending JSON data as fast as it is coming
off the wire. for example, this is output from taptap:
{"gateway":{"id":4610},"node":{"id":37},"timestamp":"2025-10-08T10:38:01.942422696-04:00","voltage_in":31.7,"voltage_out":31.4,"current":0.645,"dc_dc_duty_cycle":1.0,"temperature":15.3,"rssi":126}
2) the weewx-tigo driver captures the JSON from taptap and converts it to
weewx packets. for example, this is output from running the driver
directly. it maps the TIGO gateway/node identifiers of the form xxxx.yy to
weewx schema identifiers of the form p1, p2, p3, etc.

3) when i run weewxd directly with the driver, i see the loop packets:
