6.15. Find IP address for network loggers

!This section applies to network loggers only such as the WiFi logger, Weatherlink Live, WeatherlinkIP, some Meteobridge devices and certain other devices. It does not apply to loggers connected direct to a computer such as the Weatherlink USB and serial loggers.

Most network loggers have a web interface to use in configuring and managing the logger. This web interface can typically be accessed by entering the logger’s IP address into the address bar of any web browser provided it is on the same local network as the logger (ie remote access is not usually possible). But of course you need to know the logger’s IP address in advance before you can access the web interface. This section describes some methods for finding the IP address.

*All network devices have a unique identifier known as the MAC address, which will be a 12-character number in hexadecimal notation looking something like this: 00-1C-C0-1C-DD-08. Some loggers and other devices have this MAC address visible on a label; for example the WeatherlinkIP logger has a Device ID printed on the label on its network connector which is identical to the MAC address. If you can find this MAC address then it may be helpful in finding the logger’s IP address. All is not lost if you cannot see a MAC address – other methods should still work. But knowing the MAC address can be helpful in identifying the logger’s IP address unambiguously.

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

• 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’ in the router interface and then look for the manufacturer of the device (Davis, Meteobridge etc) or the MAC address (DID) of the logger;

• Run a simple network scanner such as AngryIP and look for the manufacturer of the device (Davis, Meteobridge etc) or the MAC address (DID) of the logger; These network scanners don’t always see every device on a network or not every device shows up at every scan, but nonetheless are well worth a try.

• Provided the network logger exposes port 22222 for connecting to local software (several of them do, but not eg Weatherlink Live) then the Weatherlink for Windows software can often be used to locate the logger’s IP address. This software can be downloaded for free as described elsewhere in this knowledgebase; And then use the Setup | Communications Port dialogue as described in the Using WLIP with Weatherlink for Windows topic.on this page.

• Certain network devices may have their own additional methods for checking the IP address. For example, Meteobridge devices have their own methods as described in the Findout Meteobridge IP in your LAN of this Getting Started web page. If your network logger has a Bluetooth interface then connecting to that via a phone or tablet may well reveal the local IP address. Or if your logger is uploading to the Davis weatherlink.com network then the IP address may well be visible there – exactly where may depend on the type of device but eg a Weatherlink Live unit’s IP address is shown on the Health Data tab of the Configuration (spanner/wrnech) menu.

• If you have a WeatherlinkIP logger then run the first step of the WLIP firmware updater (see the Firmware Update topic);
