While myenergi devices can communicate using the built-in wireless connection, there are some locations where the wireless signal will not work (for example, if your Zappi and Hub are far apart or if there are walls or metal objects in the way that block the signal). In this case, it is possible to connect the devices via your local Ethernet network. If you have the "old" version Zappi 2.0, without a built-in RJ45 (Ethernet) port, you can upgrade your wallbox for wired local Ethernet communication with this optional accessory.
No range limit
Reliable communication between your myenergi devices
Faster firmware updates
Scope of delivery: 1x Ethernet card and 1x Phillips fixing screw + nylon washer
NOTE: Only to be used for the "old" Zappi v2 wallbox
