set_device_power_status(power_status) async

Sets the power status of the device to either on or off. This method sends a request to the "setOnOff" endpoint with a specified power status parameter. The power status accepts multiple string representations: '0' or 'ON' to start the inverter, and '1', 'SLEEP', or 'OFF' to stop the inverter.

If the provided power status does not match any of the accepted representations, the method raises a ValueError with a descriptive message.

Parameters:

Name Type Description Default
power_status bool

The desired power status for the device, specified as '0', 'ON' for starting the inverter, or '1', 'SLEEP', 'OFF' for stopping it.

Returns:

Type Description
