You can turn on logging to get an idea of what the script does.
The script requires for each device to be monitored:
- a power measuring socket with a device measuring the actual power consumption named 'SC-XXXX verbruik' . The table USAGE_DEVICES contains the names of the devices to monitor for each.
- a virtual switch created with the name of the device to monitor, named XXXX
- a measurement of the level of power that is used by the machine in standby mode. Contained in USAGE_MaxWatt.
- an estimate of the number of minutes the power consumption should be lower than the standby level to assume standby to be active. Contained in USAGE_SwitchTimeOutMinutes.
- a decision wether or not to have the script send a notification when the machine is ready (off or on standby). This could also be done by attaching the notification to the virtual switch. Contained in USAGE_Notify.
The example below supports two devices, the 'Wasdroger' and the 'Wasmachine'.
