14 Linked Devices
Up to six myenergi devices can be wirelessly linked together. By linking devices, you can use more of your own
energy or have more control and visibility. Devices available now are:
eddi A microgeneration energy diverter that uses surplus power to heat water or rooms rather than
exporting to the grid.
zappi An eco-smart electric vehicle charge point that can use surplus power to charge the car.
harvi A self-powered wireless sensor that can be used along with myenergi load controlling devices
such as eddi and zappi. It is able to detect grid import/export conditions as well as generation
power and send this information wirelessly to devices such as the eddi or zappi. Using a harvi
can greatly simplify installation.
The myenergi devices can be linked using either the built-in radio or with an Ethernet cable. If using an
Ethernet connection eddi simply needs to be connected to your local network – either with an Ethernet cable
running directly to your internet router or via a power line carrier extender.
14.1 Master & Slave Devices
When two or more myenergi devices are wirelessly linked, one device will act as the master device. This device
will control the other slave devices. Some settings can only be changed on the master device, e.g. Grid Limit
and Net Phases.
Use the Set Master function in the Advanced Settings/Linked Devices menu to set which device should be
master. It's a good idea to choose the device that is the most convenient to access should you wish to change
settings.
Note: harvi will only pair with the device which is set as the master
It is recommended that, where the Grid CT is directly connected to the eddi, that this device is chosen
as the master or vice versa. This ensures the fastest response to the grid power measurement
14.2 Channels
On rare occasions it is possible that there are other appliances operating on the same frequency which could
cause interference. If it is not possible to link devices or the connection seems poor, changing the RF Channel
may help.
The channel can be changed on devices without having to re-pair them, just makes sure they are all set to the
same channel.
14.3 Removing Devices
A device can be removed by selecting it from the Advanced Settings > Linked Devices > Device menu and then
selecting Remove Device. If you want to remove all devices then use the Advanced Settings > Linked Devices
> Reset Settings menu option.
