Smart switches
evcc supports smart sockets and controllable switches. They work similarly to chargers but without power control. evcc only switches the socket on or off. If enough surplus or cheap energy is available, the socket is switched automatically.
Set up your smart switches in the web interface under Configuration → Charging & Heating.
Modes
Depending on the application there are two modes.
The standbypower parameter (standby power in watts) picks between them.
Charging mode (default)
Suitable for controlling battery-powered devices (e-motorcycles, e-bikes, tool batteries …).
The measured power at the switch is treated as charging power.
If it falls below standbypower (default 15 W), evcc treats the device as charged.
Active whenever standbypower is not negative.
Example: standbypower: 50 ends the charge once the load drops below 50 W.
Configuration example for evcc.yaml
chargers: - name: e_bike_outlet type: template template: tasmota host: 192.0.2.1 standbypower: 50Static mode
Suitable for general consumers such as heat pumps, air conditioners or heaters.
Activated by a negative standbypower value; the magnitude is the estimated power draw evcc uses for surplus calculation.
Example: standbypower: -5000 for a device drawing about 5 kW.
