energy_manager/config

Energy Manager configuration

Example

HTTP (curl)

# $HOST e.g. wem-AbCd

Read

curl http://$HOST/energy_manager/config

{ "contactor_installed": true }

Write

curl http://$HOST/energy_manager/config -d '{ "contactor_installed": true }'

or abbreviated:

curl http://$HOST/energy_manager/config -d 'true'

MQTT (mosquitto)

# $BROKER e.g. my_mosquitto.localdomain
# $PREFIX e.g. wem/AbCd

Read

mosquitto_sub -v -C 1 -h $BROKER -t $PREFIX/energy_manager/config

{ "contactor_installed": true }

Write

With MQTT on $PREFIX/energy_manager/config_update

mosquitto_pub -h $BROKER -t $PREFIX/energy_manager/config_update -m '{ "contactor_installed": true }'

or abbreviated:

mosquitto_pub -h $BROKER -t $PREFIX/energy_manager/config_update -m 'true'

Name	Description
contactor_installed bool	Indicates whether a contactor is connected that can switch the controlled chargers between three-phase and single-phase operation. Input 4 is then automatically used for contactor monitoring.
