rscp2mqtt provides the following functions to support E3/DC wallboxes.
Use "e3dc/set/wallbox/index" to switch to another wallbox, if you have more than one in your environment.
Configuration
Add this line to the .config file:
WALLBOX=true

There is a dependency of e3dc/wallbox/charge_battery_before_car to e3dc/wallbox/discharge_battery_to_car: e3dc/wallbox/charge_battery_before_car can only be set if e3dc/wallbox/discharge_battery_to_car is false (issue #21).
In addition, these topics can be published to control the wallbox:
Select the wallbox (0..7) to be used
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/index" -m "0"
The following calls will use the set wallbox.
Sun Mode (true/1/false/0)
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/sun_mode" -m true
Suspend charging (true/1/false/0)
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/suspended" -m true
Toggle suspend charging
mosquitto_pub -h localhost -p 1883 -t"e3dc/set/wallbox/toggle" -m 1
Set max current (1..32 A)
mosquitto_pub -h localhost -p 1883 -t"e3dc/set/wallbox/max_current" -m 16
Set battery to car mode (true/1/false/0)
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/discharge_battery_to_car" -m true
Set battery before car mode (true/1/false/0)
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/charge_battery_before_car" -m true
Set discharge battery until [%]
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/discharge_battery_until" -m 80
Set disable charging battery at mix mode (true/1/false/0)
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/disable_battery_at_mix_mode" -m true
Set number of phases (1-3)
mosquitto_pub -h localhost -p 1883 -t "e3dc/set/wallbox/number_phases" -m 1
If the MQTT broker runs on another server, please use its name instead of localhost and change the port if it is different.
Please adjust the calls if you use a different prefix.
