The Stand-By graph uses smart learning algorithms to detect the total power consumption of devices that are always on. The Stand-By graph can show you if you start using more or less power over time with dormant devices. Or it can let you know if you left something on if it has suddenly spiked in power. The graph shows your regular Power Usage graph in the background, with an overlay of the detected Stand-By power level per period.
The Standby graph is calculated once per day based on the data between 0:00 and 6:00. Based on the algorithms, it then estimates the total power consumed by devices that are always on, and extrapolates this data to show how much power is being used by devices during the day.
The Stand-by graph is enabled automatically if you have signed up for Energy+ at Settings > Energy+.
What is a high standby consumption?
Here are some examples of average stand-by consumption per household type.
1 person apartment:
2 person apartment: ±50W continuous, 1.2kWh per day.
4 person house: ±100W continuous, 2.5kWh per day.
How is it possible that my standby is higher than my total power consumption?
This can occur when you supply back with solar panels during the day, because your devices take the power from your solar panels instead of the grid. The standby consumption is still there, but is not taken from the grid. Another cause is that your devices were on at night between 0:00 and 6:00, which are then switched off during the day.
