weewx-purple error: no fresh concentrations to insert

[Charlie Fortner]

Problem

I'm getting  Found no fresh concentrations to insert errors thrown by weewx-purple and the data is spotty:

Did I change anything? I don't think so. It was working for months and months and then it seems to have stopped. I rebooted the purple air sensor several times.

I'm fairly certain that the connection to the purple air sensor is OK. My home assistant reads from the same sensor and its data is continuous.

System

Weewx 4.10 running on a Debian VM

With weewx-purple extension version 3.9

PurpleAir PA II Flex sensor

The log is attached.

The pertinent section of weewx.config:

[Purple]

    poll_secs = 120

    [[Proxy1]]

        enable = False

        hostname = proxy1

        port = 8000

        timeout = 5

    [[Proxy2]]

        enable = False

        hostname = proxy2

        port = 8000

        timeout = 5

    [[Proxy3]]

        enable = False

        hostname = proxy3

        port = 8000

        timeout = 5

    [[Proxy4]]

        enable = False

        hostname = proxy4

        port = 8000

        timeout = 5

    [[Sensor1]]

        enable = True

         hostname = purpleair-c2a3.lan

        #hostname = 192.168.2.173

        port = 80

        timeout = 10

    [[Sensor2]]

        enable = False

        hostname = purple-air2

        port = 80

        timeout = 66

I'd welcome any ideas about what's going on here.

It’s your long poll interval interacting with my check to see how fresh the concentration is.  Change poll_secs in the Purple section of weewx.conf to something shorter.  Let’s try 30s and report back.

In the meantime, I’ll look to change the check for freshness.  It doesn’t interact well with 120s poll interval.

I’ve released purple v3.9.1.  It considers readings stale at the max of 120s and 3 * poll_secs.

You can put your poll_secs back to 120 after you install v3.9.1.

Yep. That did it! I changed poll_secs to 30 and now things are working as expected. Thanks for the speedy response.
