Slave 1 will not start charging with load balancing

[JopGeraets]

When the slave 1 is set to smart/solar/normal when load balancing in enabled (slave node 1).
Then the charging does not start, the following is shown in telnet:

Only when the load balancing is disabled, then the EVSE will start charging.
Looks like this on debug (via telnet):`

The slave does get the current power data from the sensorbox, this is displayed on the device and shown on the webpage (only not on MQTT, which is connected to home assistant). The master EVSE does show the power data of our house at MQTT and home assisant.

I checked the wiring from the EVSE to the charge cable (using fixed cable). Both the earth and CP are connected properly.
When the cable is disconnected, 12 V can be measured between earth and CP.

I'm running version 1.7.3 of the serkri software on both slave and master.
