Problem with weewx-airlink

[anc...@gmail.com]

Hi guys,

I just installed for the first time a Davis Airlink and I want to integrate it in WeeWX with which my Davis VP2 already works. I followed the instructions on the weewx-airlink page, but for some reason it is not working . Here is some log:

As you can see, it seems to get some data packets with the values inside to be different each time, but in practice it does not put anything inside the database (I checked that the columns pm1_0, pm2_5 etc. are present with only null values). It is also curious that the Airlink is not working on Weatherlink.com, but somehow it is connected to the network because I can find it with a net scanner, and it seems that WeeWX can see it in some way with these packets you can see within the log.

Can anybody help me? Thank you!

My guess since you do not see the device in weatherlink.com is that it is not reporting correctly on the network. 

1.  First see if you can open your web browser to the api of the airlink device.

for example: http://xxx.xxx.xxx.xxx/v1/current_conditions
You should see JSON data returned.

2. Also check the APi Documentation from Davis (Introduction | AirLink Local API (weatherlink.github.io) about how the device works on a network. From their documentation, AirLink devices advertise their presence on the local network using DNS Service Discovery over multicast DNS (mDNS). These technologies are also known as Zeroconf or Bonjour or Avahi.

I have a weewx-airlink device and I followed this guide using the driver with success. Please let me know if you have any questions.

if not,

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.”

Hi,

that page gives me

curl http://192.168.0.196/v1/current_conditions
{ "data": { "did": "001D0A100829", "name": "IIS Ceccano", "ts": 506449, "conditions": [{ "lsid": 522424, "data_structure_type": 6, "temp": 86.1, "hum": 43.5, "dew_point": 61.3, "wet_bulb": 66.5, "heat_index": 86.5, "pm_1_last": 2, "pm_2p5_last": 3, "pm_10_last": 3, "pm_1": null, "pm_2p5": null, "pm_2p5_last_1_hour": null, "pm_2p5_last_3_hours": null, "pm_2p5_last_24_hours": null, "pm_2p5_nowcast": null, "pm_10": null, "pm_10_last_1_hour": null, "pm_10_last_3_hours": null, "pm_10_last_24_hours": null, "pm_10_nowcast": null, "last_report_time": 506449, "pct_pm_data_last_1_hour": null, "pct_pm_data_last_3_hours": null, "pct_pm_data_nowcast": null, "pct_pm_data_last_24_hours": null }] }, "error": null }

So it seems it has not neither good timestamp neither good concentrations. How can I fix this?

[John Kline]

Well, first, the subject of this thread is not accurate.  The problem is not with weewx-airlink.

I had a look at Davis’ Airlink manual and this case isn’t covered.  I suggest you contact Davis Technical Support:

Yes, when I started the thread I thought that the problem was within weewx-airlink, but now it is enough clear that it is the device having troubles. I think that the problem may be that it is connected to the network, but not to the internet, so it can't get the time and send data do Weatherlink.
