How MeterWatch works
From your meter’s flashing light to your phone or browser.
1. Meter flashes
The pulse light flashes as electricity is used.
2. Sensor counts
The optical sensor detects and counts those flashes.
3. Wi-Fi sends
Home Wi-Fi or a MiFi sends readings via the internet.
4. Server stores
MeterWatch stores and processes the readings.
5. You view
See your usage in the mobile app or web app.
Energy used (kWh) = flashes counted ÷ the meter’s imp/kWh rating
The sensor needs Wi-Fi with internet access to send readings to the server.
