Efergy Transmitter Tips & Advanced Settings

Over the years we've collected some tips to get the most out of Efergy energy monitors.

The following tips relate to the Efergy Elite and Efergy Engage Hub systems.

1) Adjust how often a transmitter sends data.

The transmitters can send data once every 6, 12 or 18 seconds. Reducing the transmission rate will helps to extend battery life to several years.

To change settings, press and hold the button on the transmitter for 3 seconds until the LED blinks. Press and hold again for 3 seconds to move to the next transmission rate. The LED lights correspond to the following:

  • green - least frequent update rate.
  • orange - medium update frequency.
  • red - most frequent transmission rate (default setting).


  • The LED will blink once each time it transmits data. This blink is very faint (to conserve battery power) and not easy to see outside in daylight.
  • Depending on the transmitter age and type, the refresh rates are 6, 12, & 18 seconds or 10, 15, & 20 seconds.

2) Reconnect a transmitter when having pairing issues (Elite).

Try the following steps for a full reset:

  1. Remove batteries from both the display and the transmitter.
  2. Press and hold the link button on the transmitter for 10 seconds.
  3. Simultaneously press all buttons on the display for 10 seconds.
  4. Leave both devices for 5 minutes without power.
  5. Put batteries back in both devices.
  6. Press and hold the link button on the back of the display, until the four dashes start to flash.
  7. Press the link button once on the transmitter.
  8. Wait a few seconds and you should see the energy reading on your display screen.

3) Improve the wireless connection between a transmitter and hub (or display screen).

  • Move the transmitter to outside the meter box to improve the signal strength.
  • Use high quality alkaline batteries. Rechargeable batteries do not perform well in the transmitters.
  • Keep the transmitter within 30-40m of the receiver where possible. Relocate the hub (or display) closer to the transmitter if required. Or, install the transmitter at a sub-board rather than the main meter board.
  • Don't sit the Hub directly on top of your internet router. Move the hub away from the router to reduce potential wireless interference.
  • Check if the transmitters are set to the fast transmission rate when troubleshooting. See item 1) above. 

4) Send Engage Hub data to other services.

Some of our customers use Engage together with PVOutput.org. PVOutput is a free online service for sharing photovoltaic solar panel output data. Engage data can be transferred to PVOutput either automatically or manually. Programmers and software developers can also access Engage data via the EnergyHive API.

For automatic transfer of data to PVOutput.org, see the Auto Uploader.

For manual data transfer, export from Efergy here and import via PVOutput CSV Loader.

  • Some reformatting of Efergy data is required before importing to PVOutput.
  • Uploads are limited to 200 lines of data. This is suitable for daily stats up to ~6 months per import.

Please Note: the Efergy Engage system and PVOutput are free online tools. They are not managed by Reduction Revolution. For queries relating to their use, please contact them directly.
