The device reads the electricity meter periodically. The most important data is stored in memory to be synchronized.

This option is exclusive for OneMeter Enterprise.
The device is able to read data from the meter every 1 min and advertise it. Beware one-minute data will not be stored in the memory.
Note: The existing feature of 15-min readout and storage does not change.
Depending on the quality of communication between the device and the phone and server, there may be some gaps in one-minute data that will not be filled in the synchronization process with mobile application. Make sure that the gate has a stable internet connection and is located within range of the device.
This mode has a negative impact on battery life of the device.
Data truth is guaranteed by an energy meter. The OneMeter device is not a meter (except you install it on control output). Measurements are read from the meter directly during the readout.
Do not try to read data from the other meter than the one the device was installed on.
In case the meter was replaced by the energy operator or your willingness to move the device on another meter, uninstall it first.
Data accuracy is
0.01 unit (the default for given quantity), for example
The maximal value of counter is
43 GWh approx.). In case the value is insufficient, the counters usually have a multiplier feature. In the OneMeter Cloud, there is an option to take into account the multiplier when presenting the results.
The device starts the reading sequence from the beginning of the next 15-min period in time after installation or synchronization after battery replacement. Example below.
□ (square) - moment of installation / synchronization after battery replacement
○ (circle) - moment of readout
