eddi

’s with the built-in 

vHub

 (identified by product code 

EDDI

-2Hxxxx) are supplied with a built-in Ethernet 

port (RJ45) socket and WiFi to connect 

eddi

 to the local area network (LAN).   

All 

myenergi

  internet capable devices  should be connected to the internet via either WiFi or a hardwired 

Ethernet connection.  
This version of the 

eddi 

can also act as the “gateway” or “

hub

” between all your 

myenergi

 devices and the 

myenergi

 server. The gateway device MUST be connected to the internet. 

Note: 

harvi

 can only be connected using a wireless link to the Master device 

If radio connection is not possible you have the option to tether two devices using an Ethernet cable. When 

pairing devices, they will automatically use the Ethernet link if available.   
Further detail on the Ethernet connection and WiFi see separate 

vHub

 & WiFi manual.
