The right value is "altimeter"

 There they say, that Davis uses different calculations in different 
 devices:

- VP2 and envoy consoles: sea-level pressure ("barometer", QFF)
- WeatherLinkLive: altimeter pressure ("altimeter", QNH)
- Vue consoles: user can choose between the two

 So it seems, the author of the "weatherlinkliveudp" driver read the 
 documentation most carefully. 

 And to confuse the user or something, in the LOOP data record, Davis 
 calls the value, what we learnt is altimeter, "bar_sea_level". 

 The archive record contains all the three values barometer, altimeter, 
 and pressure (I checked). Since the "weatherlinkliveudp" driver does not 
 provide a value for barometer, may be, WeeWX calculates it by itself.

Re: [weewx-user] Davis WeatherLink Live: Which driver is best?

[Karen K]

To my support question to the Davis support I finally received a reply. I 
asked them why there are differences between console value and 
WeatherLinkLive value and whether that is an accuracy issue. The first 
answer was not helpful. So I confronted them with the statement about 
different calculation. They took a long time to answer. 

And from what I understand what they wrote the Davis support does not know 
for sure. Who then?

This was their answer:
*Hello, *
*That looks like it is the case. They are calculated different. *
*To tell you the truth I was not aware of this. *
** * * *
*Tom Raymond *
*Technical Support Davis Instruments*

 There are two pressure-related elements provided by the Davis hardware.
One is the pressure as reported by the sensor, the other is the pressure
 corrected to sea-level pressure based on your altitude.The driver code
 defines which sensor values it uses for what generic weewx database element

 Both drivers map 'bar_absolute' from the hardware to weewx 'pressure'
 in the database.

 But...the two drivers map 'bar_sea_level' from the hardware to
 different elements in weewx's database.

- WLLDriver.py   puts the value into 'barometer' in weewx
- weatherlinkliveudp.py  puts the value into 'altimeter' in weewx

 According to
 https://github.com/weewx/weewx/wiki/Barometer,-pressure,-and-altimeter,
 the correction math differs slightly, so I'd expect slight differences
 perhaps.  A difference of 1 mbar to me isn't something to worry too much.
 You're talking 0.1 percent offset.  The sensor itself isn't that precise to
 begin with.

Hi,

I'm the author of WLLDriver on Github.
Yes, I think that *altimeter *is the good value. But I suggest to confirm 
that by directly ask Davis.

 That I do not understand. Does the driver only retrieves the readings

There are two pressure-related elements provided by the Davis hardware.   
 One is the pressure as reported by the sensor, the other is the pressure 
corrected to sea-level pressure based on your altitude.The driver code

Both drivers map 'bar_absolute' from the hardware to weewx 'pressure' in

According to 
https://github.com/weewx/weewx/wiki/Barometer,-pressure,-and-altimeter, the 
correction math differs slightly, so I'd expect slight differences perhaps. 
 A difference of 1 mbar to me isn't something to worry too much.  You're 
talking 0.1 percent offset.  The sensor itself isn't that precise to begin

[Didier Decoodt]

No, it is not a problem of driver,
It's OK now, the 2 drivers give the same datas.
Thank you Gary for explanations, all is clear now in my head. (meteorology
is new for me...)
Have a good week-end

That I do not understand. Does the driver only retrieves the readings from 
the hardware, doesn't it? So, which way the driver can influence which 
values is displayed?

Re: [weewx-user] Davis WeatherLink Live: Which driver is best?

[Didier Decoodt]

Ooops, after 10 mn the 2 values have diverged (only 1 mbar)
The explanation is that weatherlinkliveudp driver uses "altimeter" and
WLLDriver uses "barometer" for the station info

After change all is correct
It was not a mystery.

Re: [weewx-user] Davis WeatherLink Live: Which driver is best?

[G Hammer]

I may do that later, but I fail to see the point.
Do you think WeeWX and Davis are both applying a conversion factor to the
raw data and just happened upon the same value?

Re: [weewx-user] Davis WeatherLink Live: Which driver is best?

[Karen K]

*Weatherlinkliveudp*
(https://github.com/grebleem/weewx-weatherlinkliveudp)

No I tested the driver "Weatherlinkliveudp". I installed and activated the 
driver yesterday. By now there were no problems at all. It seems, the 
Weatherlinkliveudp driver is more reliable in terms of rain than WLL. With 
this driver it is possible to stop WeeWX without the need to kill the 
process. 

Using the anemometer transmitter kit is possible. No special configuration 
is required to do so.

I have no additional sensors. So I cannot comment on restrictions there.

[weewx-user] Davis WeatherLink Live: Which driver is best?

[Karen K]

Within the last days I did a some testing, and I read the threads regarding 
the Davis WeatherLink Live device for Davis Vantage Pro 2, and I wonder, 
which driver is best to use.

Let me summarize, what I found out about the drivers.

Just to avoid confusion:

   - "WeatherLink IP": a discontinued adaptor to insert into the Davis 
   console
   - "WeatherLink Live": a separate device to receive data from a wireless 
   Davis Vantage Pro 2 station
   
Both of them use a different protocol to communicate with the PC.

As I bought the station recently, I got the WeatherLink Live device. Then I 
looked for the appropriate driver, and I found a lot of them:

*Vantage (weewx.drivers.vantage)*

Although it is not mentioned in the documentation, I assume, that that 
driver is for the old, discontinued adaptors, only. I had a look at the 
code of the driver, and it seems so.

Could someone confirm or deny?

*WLL (users.wll)*

I tried that driver, and it works. There were 2 little problems.

First, I use a separate anemometer transmitter kit. Unfortunately, the 
driver reads the values from the transmitter kit and shows the wind, only. 
I changed the code a little bit, and now it reads the values from the 
station including the wind. I reported the changes to the author of the 
driver.

Second, if you stop Weewx, the driver reports an exception to the logs, but 
does not finish. I have to kill the process by "kill -KILL". 

Nevertheless, this is the driver I still use.

*WeatherLink Live* (recommended by Weewx)

That driver seems attractive, because it announces to use both the 
broadcast messages and the HTTP requests.

Remark for setup: Not as he documentation says, I had to set up the wind 
for ID 1 instead of 2 to get data.

Unfortunately, in my case, every now and then the log shows an error 
message, and Weewx pauses for 60 seconds. The error message reads:

Oct 31 18:39:27 LokalWiki weewx[147658] ERROR 
user.weatherlink_live.scheduler: Error caught in scheduler tick. Not

Verbindungsaufbau abgelehnt')) 
Oct 31 18:39:27 LokalWiki weewx[147658] CRITICAL __main__:  Waiting 60 
seconds then retrying... 

As the driver uses 2 different data sources, the author may want to change 
the error handling and simply queries the device by HTTP request if the 
real time broadcast cannot be activated for some reason. I think that would 
make the driver more robust. 

(Remark: I don't think, the error message is really a problem of the driver 
but rather one of the network.)

*WeatherLinkLiveJSON*

I did not test this one.

*Weatherlinkliveudp *(recommended by Weewx)

I did not test this one, because I thought, "WeatherLink Live" will be more 
than that, as it uses both ways to communicate with the device.

I can be wrong but I think I read somewhere the broadcast messages and the 
HTML request do not deliver the same set of information. Correct me, if I 
am wrong.

And in one thread I read, someone decoded the V2 API of Davis, but that 
thread gave no further information, an I see no driver that implements that.

What would you recommend a new user to use?
