Install virtual boundaries with Husqvarna EPOS™: Two installation options

Husqvarna’s satellite-based technology EPOS (Exact Positioning Operating System) allows you to create virtual boundaries for your robotic lawn mower using the Automower® Connect app. It uses RTK technology, which combines signals from the GNSS satellite system with correction data to achieve centimetre-level accuracy. Husqvarna offers two ways to receive reference data: via the Husqvarna Cloud* or with a local reference station.

EPOS via the Husqvarna Cloud

When you purchase the EPOS Plug-in for your Automower® NERA lawn mower (included on Automower® 435X AWD NERA), you receive the required satellite correction data via the Husqvarna Cloud at no additional cost*. This option offers very good position accuracy, typically better than 5 cm (2 inches), and simplifies installation by eliminating the need for a local reference station. The robotic lawn mower receives the satellite correction data via the internet and requires a constant internet connection, either through a mobile network or Wi-Fi, depending on your mower model.
*The service is only available in selected markets. Please contact your local Husqvarna dealer for information.

EPOS via a local reference station

If your lawn area lacks cellular or Wi-Fi coverage, or if the coverage is limited, you can install a Husqvarna EPOS reference station. This option involves one-time purchase and installation of the reference station. This option offers a standalone solution that is not dependent on an internet connection and provides superior position accuracy, typically better than 2 cm (0.78 inches).

Supported lawn mowers and connectivity requirements

For EPOS wire free installations, whether using a reference station or the Husqvarna Cloud, you need an Automower® model equipped with EPOS Technology.

Specific EPOS via the Husqvarna Cloud requirements

  • Requires a constant internet connection (cellular or Wi-Fi) for the lawn mower in the entire work area.
  • Mowers supporting only Wi-Fi (Automower® 305E NERA, 310E NERA, 320 NERA), can add cellular connectivity with an Automower® Connect kit, available as an accessory.
  • Mowers supporting both Wi-Fi and cellular connectivity (Automower® 405XE NERA, 410XE NERA, 430X NERA, 450X NERA) only need good cellular network coverage in the entire work area.
  • Automower® 435X AWD NERA supports only cellular connectivity, so it also requires good cellular network coverage in the entire work area.

Backwards compatibility: If you own an Automower® NERA model with an EPOS Plug-in, you can use EPOS via the Husqvarna Cloud without extra cost. However, if you already have a reference station in your garden, we strongly recommend to keep using it. Switching to EPOS via the Husqvarna Cloud will require redoing the entire installation and offers less precision, especially with Edgecut.

Troubleshooting and tips

How to check Wi-Fi and cellular network coverage

EPOS via the Husqvarna Cloud requires a constant internet connection, either through Wi-Fi or cellular connectivity, across the entire work area to receive the necessary correction data for the lawn mower to calculate its position. To test internet coverage in your lawn, consider the following methods:

With your smartphone

A smartphone can be used to first check the Wi-Fi reception quality in the lawn. ​The phone should indicate at least two bars in order for the robotic lawn mower to operate reliably . Note, that since the lawn mower and the smartphone may use different cellular technologies and networks for connectivity, the phone’s indication may not be reliable.

With the mower’s display

Drive your robotic lawn mower with the appDrive throughout your lawn to test the Wi-Fi and cellular network coverage. ​ The lawn mower display should indicate at least two bars in order to ensure reliable operation when using EPOS via the Husqvarna Cloud.

With the Automower® Connect app

​ Once EPOS via the Husqvarna Cloud is enabled in the Automower® Connect app, the reception quality of the correction data is also indicated in the app. The cloud icon should show at least two bars in order to ensure reliable operation.

Satellite search and stops

  • Seasonal and environmental conditions, such as dense trees and high solar activity, can negatively impact the satellite signal, causing the lawn mower to stop temporarily while searching for satellites. If the robotic lawn mower does not regain signal within 30 minutes, the error message Searching for satellites will be displayed in the Automower® Connect app. This is normal behaviour and doesn’t require any action. The lawn mower will resume operation as soon as its position is restored.
  • To ensure optimal performance, satellite signals require an open sky view. Buildings or trees in or around the lawn can block these signals, affecting the system’s precision. This applies to both EPOS installation options: via the Husqvarna Cloud and with a reference station. EPOS Support by Wire can help solve this issue. By installing a loop wire around areas with weak satellite coverage, you can significantly reduce the risk of operational interruptions.

Installation alternatives for optimal EdgeCut precision

To achieve best edge-cutting results with Automower® robotic lawn mowers with Edgecut, we recommend an EPOS wire-free installation using a local reference station, or installation with a physical boundary wire.
