Advertising mode

In this mode the device advertises current measurement values read from the meter (as well as additional information needed for further data processing) to Bluetooth devices within its range. If there is a OneMeter Gateway or phone with gateway mode enabled in the vicinity, the data will reach the cloud and be available to you in a few seconds.

Details

After performing a readout, the data is refreshed. Then the device advertises readouts in portions (a couple of OBIS codes per packet). If a new gateway is within its range, the device will redo advertising of some packets which may have been received by other gateway already.

After you replace the battery, you have to synchronize the device and wait for the next readout in order to see a new data on cloud.

Beware the range of advertising is greater than the range of data communication in connection with the phone.

Device state

In order to inform you about events which may require your attention, the device advertises its state. You may receive a push notification in mobile app or the cloud depending on the severity of the issue. The description what happened may differ from the one below.
