The cFos Power Brain Wallbox is able to control other EVSEes (also from other manufacturers) including load management. To do this, a cFos Power Brain Wallbox is designated as the master and the other EVSEes are connected to the master as slaves. Linking other EVSEs to a cFos Power Brain Wallbox is possible via WLAN (Modbus TCP/IP) or two-wire connection (Modbus RTU).

When using several EVSEs at the same time, the maximum possible grid connection power is often exceeded. This can save you the costs of upgrading your power connection. For single-family homes, the callable grid connection power is usually 14.5kW, if there is an electric water heating system, 34 kW.
You must set the load management mode in all slaves to "Observation" under "Settings". Under the settings for the EVSE and meter, the same TCP ports or COM parameters and the same Modbus ID must be stored as you have set in the master for the respective slave.
Yes. However, we do not recommend this because of the following disadvantages: An Internet connection is required for software updates (once the Master Slave configuration has been set up, it no longer requires an Internet connection for operation). Without an Internet connection, access to the Master Box is only possible via the cFos Power Brain Wallbox's own Access Point. You must manually set the time in the Master EVSE and update it if necessary
Without load management, the fuse could blow
As soon as you have connected your cFos Power Brain Wallbox to the home network, you can find out the network address in the router menu.
Yes, you can use the included S0 meter or a Modbus energy meter. Here you will find a list of supported meters.
Ways to use the electricity meter. If you have added meters to the configuration of each EVSE as described above and these are attached to the EVSE, the cFos Charging Manager can determine the electricity consumption and the current power drawn by each EVSE and use this for load management. Without a meter, the cFos Charging Manager assumes that the car always uses the maximum charging current allocated to the EVSE (static load management).
A cFos Master EVSE can manage up to 25 slave boxes.
With a cFos Power Brain Wallbox you can manage up to 3 third-party boxes and as many cFos Power Brain Wallbox boxes as you wish using the Charging Manager. If you want to connect more than 3 third-party boxes as slave boxes, you will need additional licences. cFos Charging Manager
