Preparing your OneMeter device

This document is related to devices with firmware version 0.20.0 or newer. If you use older version, follow the video below directly.

Before you start

We hope you already read the System overview 😉

Epilepsy warning

Make sure that the flickering light does not cause health issues for you.

Changes in installation process in 0.20.0 firmware

Since firmware 0.20.0, after waking up, if uninstalled, the device performs detection of an alternative method of energy consumption calculation. The video above does not correspond to the process accurately. The standard installation process you might have been familiar with already, has not changed though. The LED status colors has changed. We encourage you to read the details below.

Preparation for installation

  1. Download the OneMeter mobile app onto your phone.
  2. Open the OneMeter application.
  3. Sign in with your Google / Facebook / Apple account.
  4. Remove your new OneMeter from the packaging. The device should wake up when exposed to light. Use your phone's flashlight if the room is too dark.
  5. Make sure the phone has internet access, Bluetooth and GPS location services enabled.

    Caution!

    GPS location services must be enabled at least while the phone is communicating with the device. It is required for valid data transfer (related to the Bluetooth Low Energy standard).

  6. Observe the dimming light on the device. This state means the device is ready to be installed.

    ✖ Off The device is in sleep mode. To wake it up, expose the bottom to light.
    🟢 Blinking green The device is preparing for the installation process. Do not remove the battery at this point.
    ⚪ Pulsing white The device is waiting for meter communication protocol detection and installation. After one minute of inactivity, the device will return to sleep mode.
    🔴 Blinks red every second Critical battery condition or device error. If battery replacement does not help, please contact us.
    🔵 Blinking or solid blue This state should not occur. Please contact us.

Installation

We can distinguish two installation approaches depending on which port of the meter is used. The device can either read data from the meter or count power and energy consumption based on the meter LED blinking (called the control output). The description of supported meter ports is shown in the example meter picture below.

meter-ports

The device can only be installed using one of the approaches at a time!

You cannot switch ports freely afterwards. If you want to install the device on the second port, you have to uninstall it first and then install again according to the respective part of these instructions.

Installation on optical port

  1. Prepare the device to be installed.
  2. Make sure you have the Bluetooth and GPS enabled as well as have internet connection.
  3. Get closer to the energy meter.
  4. Start installation process by pressing the "+" button at the bottom right of the application.
  5. Follow the on-screen instructions. Verify the device state during the installation.

    🟢 Blinking green (stable) The device is connected to the phone. To install it on the meter, follow the instructions on the screen.
    🟢 Blinking green (variable) Installation process in progress. Wait. Do not remove the device from the meter.
    🔴 Blinking red Low battery. It must be replaced for further meter readings, installation and data synchronization.
    🔴 1 or 2 red blinks An error was encountered during communication with the meter or during data transmission.
    ⚪ 🔵 Blinking/solid white or blue This state should not occur. Please contact us.
  6. You're done👍 Wait a couple of quarter hours (15 minute intervals) and check your energy profile.

Installation on the meter LED (control output)

In this mode, the beacon is capable of measuring live energy and power consumption. The measurement is updated on the cloud within a few seconds so you can observe the load of your local grid live, apart from the standard 15-min period. The higher the power, the more quickly you will see an effect.

  1. Prepare the device to be installed.
  2. Make sure you have the Bluetooth and GPS enabled as well as have internet connection.
  3. Get closer to the energy meter.
  4. Locate the control output, similar to the one in the image above. Likely, it will be placed close to the number of pulses (blue color in the picture above).

    What if I don't see such a value?

    You can try to search for energy meter pulse constant in the documentation of your meter. In case of problems, feel free to contact us. If possible, we will prepare the list of pulse constants depending on meter model and share it with all the clients.

  5. Note down the number of pulses in kWh (convert if needed).

  6. Stick the adhesive ring to the meter so as its LED is in the center (blue circle in the picture).
  7. Attach the device to the sticker.
  8. Observe the pulse detection process.

    You may need to slightly move the device to correctly place the light detector over the diode.

    To speed up the process you can turn on any home appliance which has high power consumption for a while. When the device shines green, it is ready to be installed.

    🟢 Pulsing green faster The meter communication protocol has been detected potentially. Wait a moment.
    🟢 🔴 1 blink red Error in meter communication protocol detection. The device will come back to waiting for meter communication protocol detection.
    🟢 ⚪ Blink white on solid green Meter communication protocol was detected. Every white blink is showing a confirmation of its correct placement. The device is waiting for the installation process. After one minute of inactivity, the device will return to sleep mode. If the quality of communication degrades, device goes back to dimming.
    🔴 Solid red Low battery. It must be replaced for further meter readings, installation and data synchronization.
  9. Start installation process by pressing the "+" button at the bottom right of the application.

  10. After you connect to the device, a new window will appear - input the previously noted number of pulses and continue.
  11. Follow the on-screen instructions. Verify the device state during the installation.

    🟢 Blinking green (stable) The device is connected to the phone. To install it on the meter, follow the instructions on the screen.
    🟢 Blinking green (variable) Installation process in progress. Wait. Do not remove the device from the meter.
    🔴 Blinking red Low battery. It must be replaced for further meter readings, installation and data synchronization.
    🔴 1 or 2 red blinks An error was encountered during communication with the meter or during data transmission.
    ⚪ 🔵 Blinking/solid white or blue This state should not occur. Please contact us.
  12. You're done👍 Wait a couple of quarter hours (15 minute intervals) and check your energy profile.
