Ethernet and zappi v2.0 / eddi v1

Although the latest versions of zappi, eddi and libbi all come with built in WiFi and Ethernet, the older models only use a radio link to communicate with each other and the myenergi hub.

Where the radio link is weak it is now possible to install an Ethernet adaptor to allow the devices to communicate with each other over a wired Ethernet link:

• zappi 2.0 Ethernet board
• eddi 1.0 Ethernet board (coming soon)

NOTE: As the Ethernet boards need to be fitted inside the zappi / eddi this should only be done by an approved installer or someone who is competent to carry out the work safely.  Always ensure that the mains is turned off at the main fuse before opening the cover of the zappi or eddi

Important considerations...

• With the original zappi and eddi, you will still need a myenergi hub to connect to the Internet, even if you have fitted the Ethernet boards
• It's not essential to fit Ethernet boards in every device - only between the devices that are having problems communicating over the radio link.  Consider an installation with a zappi (master), eddi and a hub.
  
  • If the zappi and eddi are struggling to communicate then both will need to have Ethernet boards fitted
  • However, if the zappi and the eddi are communicating OK, but the eddi cannot reach the hub, then it's only necessary to fit an Ethernet board in the eddi.

Further important points...

• All the myenergi devices need to be on the same part of the network - in most cases this is not an issue, but if you have split your network up into different segments using VLAN's or a second router you may run into problems.   Check that all the myenergi devices are on the same VLAN or router
• Finally, if the network still does not seem to be working you may find that you need to turn the Ethernet off and on again.
  • Try turning the power to the devices off and back on again, or
  • In the Bootloader menu there is a setting to turn the Ethernet on / off

Checking that the Ethernet port is working

On the zappi check the Readings menu, page 8/10

You should see a screen like this:

The Enet Tx / Rx counters show the packets being exchanged between the myenergi devices.

Note - this is not traffic to the Internet, just between the devices. 

FAQ's

• Is it possible to PING the Ethernet port to check it is working?
  No - the Ethernet board does not respond to PING.  You can check if it is working by checking the Enet Tx/Rx counters on the Readings menu.
