Negative or inverted power measurements

The sensors used in Eyedro Electricity Monitoring systems are directional. It is common for one or more sensors to be installed ‘backwards’ resulting in negative or inverted power measurements being reported. Rather than having to go into the electrical panel to physically flip the sensor(s), the sensor polarity can be inverted in the MyEyedro cloud software using one of the methods below.

Method 1: Device Health Check _{(Recommended)}

Open MyEydro and log into your user account.
Navigate to the Device Configuration plugin.
Select the desired device from your device list.
Click the Health Check button from the device info panel.
Turn on a significant load that can be seen on all sensors (i.e. a large heating or cooling appliance).
Run the appropriate command in the Health Check dialog.
- For EYEDRO-HOME (single-phase) products, click the Run Polarity Detection button.
- For 3-Phase products, click the Run Phase Angle Detection button.

Additional documentation for the Health Check can be found in the MyEyedro User Guide here.

Method 2: Device Settings _{(EYEDRO-HOME and single-phase only)}

Open MyEydro and log into your user account.
Navigate to the Device Configuration plugin.
Select the desired device from your device list.
Click the Edit Device button from the device info panel.
Navigate to the Sensors tab.
Locate the Sensor Inverted setting for the desired sensor and change it from No to Yes (or vice versa).

You did all this but it keeps changing polarity!!!

EYEDRO-HOME and Single-Phase

Make sure your Eyedro device is not plugged into an Uninterruptible Power Supply (UPS).

If you have solar or other generation, ensure that when you run the Health Check the consumption greatly exceeds any generation. If possible, turn off the inverter that ties the generation into the panel. When configured correctly, periods of consumption will appear as positive and periods of (net) generation will appear negative.

3-Phase

Ensure your 3-Phase configuration settings match the circuit being monitored and the Eyedro device is powered by the same circuit that is being monitored.

Make sure your Eyedro device is not plugged into an Uninterruptible Power Supply (UPS).
