You’re getting this because the timestamp is bad:
'ts': 85460
The specific message: user.airlink: last_report_time must be time since boot:
85441 seconds.
is worded that way because I found airlink was reporting time since reboot
(rather than time since epoch). I observed this behavior until the airlink
started reporting concentrations. I specifically check for pm1 to determine
this state. In the case below, pm_1 is missing ('pm_1': None).
I wouldn’t try to get this running in weewx until you have good data. In a
browser, go to:
http://<airlink-url-or-ip-address>/v1/current_conditions
You need a good timestamp to show up here (e.g., right now, "ts": 1653499667)
and good concentrations (rather than None); e.g., "pm_1": 5.16
Since it’s finding no valid concentrations, you are seeing the message “Could
not get concentrations from any source.”
