Davis WeatherLink Live

[garybixler]

Hi Jim

Everything works perfectly. I was wondering if maybe we could replace 'Rain Size' with a more useful reading like 'Rainfall year' . I finally found that Rain Size just means what the spoons are calibrated to tip at (factory set). Either 0.01 inches or 5 mm . Even though the spoon calibration can mechanically be adjusted I don't think this reading will change. It also can't be changed through WeatherLink software.

Thanks Gary

[bpwwer]

Ah, that makes more sense now. For some reason I was thinking that rain size had something to do with the size of the raindrops.    Since the rain data is reported as bucket tips, I should be using this to do the calculations instead of a fixed 0.01 inches. I'll make that change and switch out the rain size on the display as well. 

Thanks!

Hi Jim

I just saw the update in the store and gave it a try. It comes back with pullRepo: undefined.  I also stopped weatherlink and tried the update  but same result.

Thanks Gary

I tried again and rebooted the ISY and PolyGlot and all is working now.

Thanks

Hi bpwwer

Weather Link has been working great. Thanks. I have run across one issue. The Yearly rain doesn't appear to be conveyed from the NS to the ISY. I don't see that filled in on the admin console. I do see it in the Weatherlink NS log however.  I think it has always been filled in until I upgraded to v.5.0.16b.  Not sure that would have anything to do with it or not.

No rush at all but maybe take a look later.

Thanks Gary

Update: Yearly rain showed up after I started receiving some rain today. So it seems to be working. I had thought that a query would have brought it up.

Thanks

I don't see Weather Link as an option to add in the node listing. Is it under another name? 

 

[garybixler]

It is in the  local polyglot nodeserver store called WeatherLink. It supports the Davis WeatherLink Live unit.

It looks like it should be reporting it.

However, it only reports the reading to the ISY when it changes.  If you look at the nodes in the polyglot dashboard. It's GV5 in the main controller node.  Does that have a value that matches the data in the log?   I think, because I tell the polyglot to only update the ISY when it changes, it's possible that upgrading the ISY, cleared the values in the ISY, but polyglot hasn't seen a change in the value so it hasn't sent an update.

It works this way to reduce the load on the ISY.

For a lot of my node servers I started forcing polyglot to send the values when the node server starts to as a way to work around this, but this one doesn't do that.  I'll have to update it otherwise, you'll probably not see that update until you get more rain.

[garybixler]

It did resister when I starting getting rain. After rebooting the ISY after an update  "yearly rain" didn't get filled in. I thought a  query on the NS would bring it in but didn't.

It is fine now but after the next re-boot of the ISY it will probably not show up again until rain is detected.

Thanks Gary

I have a Davis weather system that updated to the web and would like access to that. It plugs into my PC with a USB plug. Are you aware of any information as to how to configure this in Polisy? 

 

[garybixler]

@bpwwerHi, I had an error occur  early this morning so I thought I would pass it along.  I would see an error similar to this if I had requested the data from the PC while polisy was still polling. I assume the weatherlink live can't support more that one connection at a time. This was early in the morning and nothing else accesses the weatherlink live so I am not sure why the error popped up. It is Ethernet connected powered by POE on a UPS backed up switch.  This has never happened just out of the blue. Restarted and runs fine again. 

Thanks Gary

@Tominnh Hi, I have the Davis Weather console connected using the IP dongle.  This works well to update to the WeatherLink cloud and have local access using a PC running  the proprietary WeatherLink software. However as far as I know there has never been an API available for 3rd party access until the WeatherLink Live came along.

Gary

Just did a little search and there may now be an API available for WeathLink.com

@bpwwer Thanks so much.

Gary,

Near the bottom of the "DarkSky Acquired by Apple" forum topic, I asked about a Weatherlink IP nodeserver.  There, I provided the api documentation to Bob.  He is going to take a look.

Thanks,

Thanks for the report Gary.  Looks like WLL refused the connection for some reason, as it started working after the restart, I assume it must be a temporary failure.  I added error trapping to the request so it shouldn't crash if it happens again.

[garybixler]

Thanks,  I just installed the update. I'm thinking that it may have been a reboot for what ever reason that caused the disconnect. I think I'll add it to ping and see if it does go offline.

@bpwwer  Hi, weatherlink live works great. The only thing that causes a problem is when the app is connected.  It causes the NS to stop with errors. I don't know if that is because the weatherlink live doesn't allow more than one connection at a time or not. I copied the log showing the errors.

Also I ran the APP for several minutes and had no problem from that.

Thanks for the APP fix.

Does WLL work with extra sensors? I have 2 extra Temp/Hum sensors Garage & Shed, and two extra Temp sensors Pool & Pool Heat Return attached to my Davis Vantage Pro. I have yet to learn they will be accepted and transfer through the WLL.

The node server doesn't support any extra sensors. It pulls data from the 'current' 'indoor', 'soil' sections of the data.  It only pulls one temperature/humidity value from the 'current' section.

I can add more values, but would need to see the actual data from WLL with the additional data as I don't have a Davis system.

Hmmm. That’s the thing- I’ve been on the fence about getting the WLL because I can’t seem to find out if it is capable of even fetching or passing extra sensors data. The documentation says ‘any 8 sensors’ but Davis has, in my experience, always been less than transparent regarding limitations or work around of their products. 

I will dig further (or someone could chime in). I would be willing to share My station data if it turns out there is data to be had!

[kp3]

After reading the following article

https://www.manula.com/manuals/pws/davis-kb/1/en/topic/weatherlink-live

my head is exploding. It appears Davis wants to control when the WLL will spew even current conditions data. 
I'm having trouble understanding whether The article is referring to data from the WLL or data from a WeatherLink.com account generated by WLL data.  This v1 vs v2 api is beyond me.
     I really have zero interest in seeing my data via a weatherlink site. I use a third party application to collect and graph all my data. The sole purpose of the WLL pursuit here was to hopefully be able to capture real-time extra sensor data for use in ISY programming decisions. 
     I’m still lost if that is possible and am unwilling to spend $200 to find out. 
    Does any of that info lead you to believe we can pull data off the WLL before having anything to do with weather link.com and their account/subscription/data control requirements?

[bpwwer]

My node server does pull data directly from the device, I'm using the V1 API and it can be configured to pull as often as you want.

It currently does not handle multiple sensors, at least not correctly, so I'd have to make some modifications to handle additional outside temp/humidity sensors and I'd need to see what the data looks like to do that.

From looking at the docs, it appears that the WLL device does support multiple sensors for the current conditions, but I'm not sure I'd bet my own $200 on that.
