Insight
An Insight socket output can look like this:
```

"onTotal": 47939,
"averagePower": 13,

}
```
Some information about those power parameters:
+ `state`: Whether the device is currently ON or OFF (1 or 0).
+ `onSince`: The date and time when the device was last turned on or off (as a Unix timestamp).
+ `onFor`: How long the device was last ON for (seconds).
+ `onToday`: How long the device has been ON today (seconds).
+ `onTotal`: How long the device has been ON total (seconds).
+ `timespan`: Timespan over which onTotal is relevant (seconds). Typically 2 weeks except when first started up.
+ `averagePower`: Average power consumption (Watts).
+ `power`: Current power consumption (Watts).
+ `energyToday`: Energy used today (Watt-hours, or Wh).
+ `energyTotal`: Energy used in total (Wh).
+ `standbyLimit`: Minimum energy usage to register the insight as switched on ( milliwats, default 8000mW, configurable via WeMo App).
## Lookup Node
This node queries the current state of a device, when an input message is injected. The output is very similar to that of the Input node.
