Electricity use sensor
No surprises on your electricity bill
Keep track of how much electricity your household uses.
See how much electricity you are using at any time.
Compare days, weeks or months of power use.
One size fits all
The sensor counts the light pulses on your power supplier's meter.
Lower your bills
It can be confronting to see how much a new TV raises your average electricity use.

Each electric device in your home has a unique power usage fingerprint. By using "power disaggregation" algorithms your supplier could figure out which specific devices you own.
If you ask, your supplier could promise to disable measuring your data remotely. But then you are still handing them the power to re-enable this at any time, and your home is still connected to a network, which is always a security risk.
