Hello,
With lots of good help from the group, I have my Seeed CO2 monitor (LoRa)
sending data to my weewx.sdb archive. I have weewx 4.5.1 (setup.py) on
Focus Ubuntu.
The sensor sends data only every 60 minutes and my archive update is
every15 minutes.
Looking at weewx.sdb, I have a reading recorded every hour but a null every
15 minutes when there is no new data.
co2 column
417.0
null
null
null
390.0
null
null
null
394.0
My settings in (Standard) index.html.tmpl are:
Current Conditions
<td class="stats_label">CO2 level</td>
<td class="stats_data">$current.co2</td>
Sometimes I get a data reading and others just "N/A"
My settings in weewx.conf:
[MQTTSubscribeService]
# Turn the service on and off.
enable = true
binding = loop
[[[mytopic]]]
ignore = true
[[[[CO2_Value_PPM]]]]
name = co2
ignore = false
contains total = false
conversion type = float
Since everything seems to be working, the "$current.co2" may not be the
correct form to use here as the display needs to retain the last value
until it's replaced with a new reading coming every 60 minutes from the
sensor.
Much appreciated if someone could point out my mistake in configuration
here.
The display can be seen at: http://grattans.org/wx
Cheers,
Bob
