How to Connect devices via Ethernet or Wi-Fi

Important

This article applies only to myenergi devices with built-in Ethernet or Wi-Fi. These can be identified by the letter "H" in the product reference (e.g. ZAPPI-2H07TW).

The latest myenergi products feature built-in Ethernet and Wi-Fi, in addition to the original wireless link, offering multiple options for connectivity. This article explains the available connection methods.

Note: At least one device in your myenergi network must be connected to the internet to enable firmware updates, remote monitoring, and control via the myenergi App and myaccount.
Additionally, from July 2022, all EV chargers in Great Britain must be smart and connected to the internet as per legal requirements.

Connection Methods

Ethernet (Wired Connection)

Wi-Fi (Wireless Connection)

Radio (Wireless Link Between myenergi Devices)

A wired Ethernet connection provides the most stable and reliable internet connection for your myenergi device.

How to Connect via Ethernet:

Turn off the power before opening the device.
Connect an Ethernet cable to the RJ45 socket inside the device.
Ensure the other end is connected to an internet router.
Secure the cable firmly to prevent disconnection.
If necessary, drill an entry hole in the case and fit a suitable gland to maintain the IP rating.

If running an Ethernet cable is not practical, Wi-Fi is the next best option.

Wi-Fi provides a flexible and convenient way to connect, though performance depends on signal strength at the installation location.

How to Connect via Wi-Fi:

Ensure strong Wi-Fi signal near the device (test by checking Wi-Fi on a phone nearby).
Follow the Wi-Fi setup guide → Click here for instructions.
If the signal is weak, consider boosting it with one of the following:
- Mesh Wi-Fi systems (e.g. TP-Link, Netgear) – improves overall coverage.
- Powerline Adapters – extends the Wi-Fi signal via electrical wiring. Ensure you select one that works as a Wireless Access Point.
- Wi-Fi Extenders – simple plug-in boosters (performance varies).

All myenergi devices use a built-in radio link operating at 868MHz or 915MHz (depending on region), allowing communication without Wi-Fi or Ethernet.

The harvi always operates over this radio link.
In locations where Wi-Fi is unavailable, the radio link may provide a more reliable connection.
Older myenergi devices that lack Wi-Fi or Ethernet must use the radio link.

NOTE: If you have a libbi, you must use a vHub instead of a standard hub.

Additional Equipment

If Wi-Fi is not an option and your myenergi device does not support Ethernet, you can purchase a myenergi hub for connectivity.
