General points

The WLIP does not necessarily need any local configuration at all – in many cases it should only be necessary to connect the logger to an Internet-enabled network connection and to register and update the logger’s account at weatherlink.com. But if any problems are encountered then some checks from local software can be helpful for troubleshooting.

But if you do wish to use some of the diagnostic steps outlined below, you will need to be running a Windows PC. The WLIP firmware updater is only currently available as a Windows utility and only Weatherlink for Windows (ie and not Weatherlink for Mac) supports the IP logger.

Please remember that communications from local software to a WLIP logger must typically happen with the PC running the software connected to the same subnet of the same network as the logger. This will almost always be the case anyway for small and domestic networks, but networks in larger organisations may need checking more carefully. And note also that the WLIP logger is intended as a network device and not for connecting directly to a PC – communications occurs via the local network, not via a wired connection direct from logger to PC.

Weatherlink for Windows software

The Communications Port dialogue in Weatherlink for Windows (see right for example – and accessed from the main WL Setup menu) provides tools for checking and configuring the WLIP logger.

To set communications for the WLIP logger, select the TCP/IP option at the top as the Communications option.This will enable the TCP/IP panel midway down the dialogue.

Do not attempt to change the TCP port away from its default value of 22222 (unless you have some very unusual and specific reason for doing so) – there is hardly ever any need to change this value.

For local diagnostic purposes you will usually want to select the ‘Local Device ID’ option (even if the normal TCP/IP mode might be ‘Web Download’ for instance). The textbox to the right will often be blank at this stage, although it should fill in with the logger’s DID value (its MAC address in other words) if a logger is found.

Click the Find button.

Weatherlink will search the local network and if a WLIP logger can be found then a small message will pop up as shown left, displaying the IP address of the logger, along with its DID/MAC address. Make a careful note of the IP address for future reference. If, however, you see an error message to the effect that no logger can be found then there’s clearly a problem with the logger not being functional for some reason and that will have to be followed up.

If WLIP uploads to weatherlink.com are not working but you can find the logger with a valid IP address as outlined above then it’s worth checking whether the local Weatherlink software can receive data direct from the logger across the local network. We would suggest working as follows:

  • Create a new test station in Weatherlink. (Even if you already have a station set up to receive data eg by Web Download, it may well be worth setting up a new station simply to avoid test data potentially getting mixed up with existing data. But remember to switch the station back to your normal station once testing is complete.)
  • Configure the new test station to use the ‘Local Device ID’ setting in the Communications Port dialogue, as above;
  • Try running the Bulletin screen (which often takes a couple of minutes to initialise with a WLIP logger) and downloading a block of archive data;

If both Bulletin and archive data are flowing normally then any problems with uploads to weatherlink.com are almost certainly being caused not by the logger but by a failure of the data to flow out on to the Internet at the router – typically this will be a firewall issue that will need sorting out by your local network support.

NB In the uncommon scenario that two or more WLIP loggers are connected to the same network, you will need to repeat the process of pressing the Find button and checking any reported IP against its DID until you find the particular logger of interest.

If you do routinely use the Web Download option, remember to reselect this in the Communications Port dialogue and check that the account credentials are still correct before concluding this troubleshooting process.

Finding the IP address for the WLIP logger

There are actually a number of different ways to establish the IP address of a WLIP logger:

  • Use the Weatherlink for Windows software as outlined in the section above;
  • Run the WLIP firmware updater (see below);
  • Inspect the DHCP table in your router settings, which (depending on the router model) may allow you to see the assigned IP address directly. Look for an entry termed something like ‘View attached devices’;
  • Run a simple network scanner such as AngryIP;

Updating the WLIP firmware

Updates to the WLIP firmware are released from time to time. The current version (May 2015) is v1.1.1.

Often the updates are relatively minor and there’s not automatically a need to update just because a new version is available. But updates are sometimes important, for example as from May 2015 uploads to weatherlink.com from firmware older than v1.0.8 will stop working and, in general, it does no harm to check the Davis website for updates at regular intervals.The changelog on the Davis website (see link below) usually gives an indication of the significance of each update.

Your IP logger’s curernt firmware version can be found in one of three ways:

  • (Simplest): Log on to your WLIP logger account at weatherlink.com and look at the ‘My Account’ tab. In the ‘My Device’ section towards the bottom you’ll find the current ‘Firmware Version’ line;
  • Look at your IP logger’s web interface (see next subtopic further below)
  • Run the firmware updater (see following notes);

The latest firmware for the WLIP logger can always be downloaded from the support section of the Davis website and specifically from the Weatherlink section at www.davisnet.com/support/weather/downloads/software_frmwr.asp. The download is in the form of an exe file that can be run directly on Windows systems once downloaded.

Running the updater

Running the updater displays the simple dialogue shown right. The updater runs in two stages. First, as it opens, it will automatically look for an IP logger on the local network and, if one is found, the DID and IP address will be displayed. If there are two or more local WLIP loggers then click the Find button until the particular logger of interest (as verified via its DID) is displayed. (IP loggers on remote systems, ie not on the local network, can also be updated. In this case, select the Remote IP Address option, enter the public IP address of the remote logger and press Find to verify that the logger can be seen.)

For the second stage, click the Start button.The Firmware Information dialogue box will appear advising you of your current Firmware version. You can choose to proceed with the update or cancel out of the firmware updater. If you do proceed then the latest firmware will download to the logger over the course of a minute or so – as with any firmware update, do not interrupt this download until it has completed. When complete you should see a dialogue message advising of a successful update. In the unlikely event that the update was not successful then it may well be worth trying a second time. (NB Once the update has started it will proceed even if the existing firmware version is identical to the ‘new’ version, but this shouldn’t be a problem – it will simply result in a new copy of the same firmware being loaded into the logger.)

The WLIP logger should then restart automatically with the new firmware now active.

For those preferring to view a video, instructions for performing the firmware update are also available on a Youtube video on the Davis channel..

Viewing the WLIP web interface

It is sometimes overlooked that the WLIP logger does have its own very basic web interface (see right).

You must know the IP address of the WLIP logger before this web interface can be called up. (See section above for finding the IP address.) Once known, this IP address can simply be entered into the address bar of any standard web browser (Internet Explorer, Chrome etc) as, for example, http://192.168.1.7 (but obviously replacing the IP address with your own value). This should cause the web interface to be displayed, although it may take some seconds before the logger responds and occasionally it may require one or two further attempts to display the interface.

The purpose of the interface is to provide a means of making very basic changes to the logger’s configuration, but it also reports the details of the logger’s current configuration, e.g. the current firmware version is shown highlighted at the top.

In practice, most users will hardly, if ever, need to change these settings and our strong advice is not even to try playing with the settings – with the wrong values it is easily possible to stop the logger communication at all on the network and the logger is then potentially useless for ever. You have been warned!

But for the rare occasions when some change to the settings may be required, there are two main settings to consider:

  • Switching the logger from automatic assignment of IP address (DHCP) to manual assignment. Note that all values in the various network settings will need to be 100% correct before the settings are saved;
  • Turning off the automatic uploads to weatherlink.com – see the checkbox to the right of the configuration screen. This setting may occasionally be preferred for maximum reliability if the prime use of the WLIP logger is to feed data across the local network to a computer for local processing and uploads to weatherlink.com are of no interest.
