ftpuploader timeout with Davis Vantage Pro2 - Weewx on CentOS 7

[Kevin Phillips]

I am trying to get back into Linux after several years away.  I recently installed CentOS 7 on a Dell OptiPlex 790.  It has an Intel i5-2400 3.10 ghz process and 4GB of RAM.  I installed weewx 3.9.2 from the rpm package.  I have a Davis Vantage Pro2 model 6162 weather station.  It has a wireless console with the data logger.  I recently upgraded the console firmware to v3.80.  The computer is dual-boot with Win7 Professional 64-bit on the other side.  I have been using the Davis Weatherlink software to uploaded data to their website which then disseminates it to CWOP and Wunderground.  I have not been able to get weewx to upload similarly.  I am using FTP with the same parameters entered in weewx.conf as I have in Weatherlink.  I recently upgraded the kernel to 5.3 after reading some information indicating it might have better hardware support but that did not help.  The Davis console is connected to the computer with a USB cable.  In CentOS it is connected at /dev/ttyUSB0.  I can enter wee_device --info and get various error messages regarding the console sleeping/waking up.  I will copy two of these messages below along with a sample of the log.  The console will usually wake up after 2-3 attempts like this.  I have been reading blog posts and have seen several instances of similar behavior but I have not found an exact match for what I am experiencing nor have I have a clear solution.  I appear to be able to FTP to the Davis site manually.  Any help is very much appreciated.  Thanks,  Kevin

Your installation is actually running properly, but there are 3 issues:

1. This log entry gives a clue to one of your problems:

Oct 15 05:43:12 RadioShack weewx[4433]: **** device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Oct 15 05:43:12 RadioShack weewx[4433]: **** Is there a competing process running??
Oct 15 05:43:16 RadioShack wee_device[5135]: vantage: Max retries exceeded while getting EEPROM data at address 0x29

You cannot run wee_device and weewxd at the same time. They both need to control the console. Run one or the other, never both.

2. Are you sure that www.davisinstruments.com supports FTP? When I try it, the connection just times out. I would be very surprised if they did.

3. Your console has a very long archive interval (1800 seconds, or half an hour). That means it will generate reports and do the FTP upload only every half an hour. Consider changing it to 5 minutes by using the utility wee_device with the --set-interval option.

Thanks for the reply.  I thought it seemed to be working from what I could tell.  I have re-set the archive interval to 5 minutes.   In terms of whether or not I'm sure their website supports FTP, my answer has to be "no".  Their Weatherlink software in Windows has FTP settings in the Internet Settings window (FTP hostname, FTP logon name, FTP path, etc).  I had also written Davis Support to ask if anyone had any ideas about this.  One person responded by telling me to try the davisinstruments.com setting (It had originally been davisnet.com from when I first got the station and set up the software).  When I replied that that did not work, a different person responded and appeared to say that the site did not support FTP but the reply talked in terms of initial set-up of Weatherlink which I have had running for a couple of years.  The response was that I just follow the prompts and "it just uploads".  While I do agree that the Internet is magic, this was not quite as helpful or technical response as I had hoped for.  ;-)  They did not respond after I pointed out the FTP jargon in Weatherlink.  So, my question is:  if it does not support FTP, how should I set up the Davis site in weewx?  Thanks again.  Kevin

The standard approach is to host your own website on a hosting service that supports FTP or rsync. There are tons of them out there. Personally, I use Amazon Web Services, but that's not a simple system. Others are GoDaddy.com, or hostgator.com, dreamhost.com, and many, many others.

I don't know anything about WeatherLink, but I suppose it makes the same assumption: that you will be hosting your own website, and, if you put in the proper credentials, WeatherLink will FTP files up to it. But, as I said, I don't know anything about the program.

Now, posting to the WeatherUnderground and/or CWOP is a completely different thing. That is done using HTTP, not FTP.

I will see if I can get any information from Davis Support about what their site might use.  I created an entry in weewx.conf similar to the one for Wunderground.  I tried two sets of information:  one using the Device ID and key generated by the WeatherLink software and another using the user-id and password I use to log onto their website.  Neither one worked to upload data to their site so I guess it is not HTTP.  I enabled both the entries for Wunderground and CWOP and both appear to be working now so that's the most important thing to me.

Thanks

I posed the question to Davis Support of "how" their WeatherLink software uploads information to their site.  I haven not yet received a direct response from them but I received this evening what appears to be a generic message that might contain some clues.  I don't know if someone directed this to me or whether this was directed at anyone using their WeatherLink software.  Here it is:

Dear Developers,

There are upcoming changes to api.weatherlink.com that may affect those using SSL to make requests to https://api.weatherlink.com/. The upcoming change will disable support for outdated versions of TLS. Developers using our API without SSL will not be affected.

Changes:
On Monday, November 4th, 2019, TLS version 1.0 will be disabled on https://api.weatherlink.com
On Monday, January 6th 2020, TLS version 1.1 will be disabled on https://api.weatherlink.com.

Background: TLS 1.0/1.1 protocols have known security vulnerabilities and most modern web browsers will remove all support for TLS 1.0/1.1 in January of next year. TLS version 1.2 was originally released in 2006, therefore most of you should already support these newer protocols. Concerned application developers or those operating applications that support critical infrastructure should ensure software is up-to-date to support TLS 1.2 and modern encryption ciphers.

Thanks,

Davis Instruments WeatherLink Team.

Kevin,

I don't think there is much of a mystery here. The Davis site does not support FTP. I would be surprised if they did: that would make them just another website provider, which they are not.

What they do support is a proprietary HTTP "RESTful" upload protocol for their WeatherLink customers. That generally requires a subscription, although they do offer a crippled version for "3rd parties", which would be us. However, we do not offer such an upload extension, and have no plans to do so.

So, you will have to either

1) Set up your own website with a hosting provider. Several were suggested in an earlier email.

2) Be satisfied with a website on your Local Area Network, that is, your house. You can supplement this with uploads to CWOP or WeatherUnderground, or one of the many other upload sites WeeWX supports. Unfortunately, WeatherLink is not one of them.

3) Give up on WeeWX and go all Davis. Buy their WeatherLink Live logger, or use a regular logger, but run their WeatherLink Computer Software on a computer. Either way, you would need a subscription. See their website for details.

Got it.  Thanks for the input.
