Reference station communication problem—Automower® with EPOS® technology error message

The error “Reference station communication problem” indicates that your Automower® robotic lawn mower has lost its connection to the reference station during operation.

Check power supply and restart devices

Connection issues can often be resolved by restarting.

Check the power supply

Verify that the reference station is connected to the power supply.

Restart your devices

  1. Turn off the robotic lawn mower and then turn it back on.
  2. Unplug the reference station, wait for one minute, then plug it back in.

Verify correct installation

The reference station may not be installed correctly.

  • Full sky view: The reference station needs a clear view of the sky (minimum 135 degrees).
  • Minimum height: The reference station must be installed at a height of at least 2 m/6.5 ft.
  • Distance to the lawn mower: The distance should be less than 100 m/330 ft. If there are objects in between the lawn mower and the reference station, the minimum distance may be reduced.

Check for interference

Interference from other devices may disrupt the connection.

Interference from another reference station or nearby radio systems may disrupt the connection.

  • Check for metal objects, such as metal fences, near the reference station.
  • Unplug the reference station, wait for one minute, then plug it back in.
  • If the problem persists, contact your Husqvarna dealer.

Pair or reinstall the reference station

Steps for pairing and reinstalling.

Pair the mower with the reference station

  • If you haven’t paired the reference station with your mower yet, this must be done for it to work.
  • During installation of Automower® in the app, you will reach the EPOS® setup step to pair your reference station.
  • Follow the steps in the EPOS® installation guide to view the complete setup.

Reinstall the reference station

If your reference station is already installed, try reinstalling it in the app:

  • Go to the map and scroll down to Reference station.
  • Select Reinstall and follow the instructions.

Technical issue—LED flashes red

A red flashing LED indicates a technical error.

  • Disconnect the power supply, wait for one minute, then reconnect it to restart the reference station.
  • If the LED continues to flash red after restarting, contact your Husqvarna dealer.

Check signal coverage

On very large or hilly lawns, the reference station signal may not cover the complete work area.

The reference station must cover your entire work area. In specific cases, such as in very large areas or areas with hills or large buildings, the signal may not reach all parts of the work area.

Solutions:

  • Move the reference station to a location where the signal reaches all work areas.
  • Create a stay-out zone to exclude shadowed areas from the installation.
  • Contact your Husqvarna dealer to assess the site. In specific situations, a second reference station can be installed to extend the signal.
