OneMeter provides a bundle of features and racks up value over time.

What exactly is OneMeter?

OneMeter turns your power meter, into a smart power meter. Read, analyze and assess your power usage in near real time.
OneMeter installation is so easy that anyone can do it. You just need to place it on the optical port of your meter. The beacon is affixed with a magnet, so you can easily remove it. OneMeter beacons don’t interfere with meters (confirmed by certificate) so there’s no reason why the DSO would prevent you from using our device. On the other hand, you have the right to read your meter in the same way they do.
OneMeter works with energy meters that have an optical port compliant with IEC 62056-21 / IEC 1107 standards. Our beacons have been tested on the majority of models produced by common manufacturers, such as: Apator/PAFAL, Elgama, Elster, Landis+Gyr. You can check the full list of compatible energy meters here.
OneMeter uses communication working in the 2,4 GHz range. All exchanged data is encrypted by unique keys with the AES-128 protocol.
The OneMeter beacon is powered by the CR2032 3V battery, commonly found in kiosks and home appliance shops. The limited version works from 8 to 12 months on one battery (depending on the meter model). The pre-order version provides a full year of battery life.
The beacon won’t work without a battery. Having replaced it with a new one, the beacon will continue to work and the data collected previously in its memory won’t be lost.
Run our mobile app after connecting the beacon to your meter. Tap ADD BEACON and simply follow the instructions provided. The process should take less than a minute!
The Cloud App is a web application that provides quick access to complete data from your meters. It also formats comprehensive reports in addition to presenting readouts in detail. Cloud App is available at:
