The Network Owl Gateway uses a 5V dc feed supplied by a 240V transformer/adapter plug
The power consumption = 0.5 watts or approx.. 0.011 amps
Some customers try to place the unit on a timer to save money, this is false economy, timers can easily consume more power than they save in this case and as you can see the power consumption is negligible.
The unit should be powered on at all times to accurately collect data from the wireless units paired to it. If the units is powered down it will be unable to collect data from electricity transmitters data gathered will have long periods of missing data
