Software version This option is valid from software version 1.18.x.y onwards.

Note

Note

Operating system The Sofar broadcasts its IP address through mDNS. This protocol is supported on Windows 11 and newer builds of Windows 10. Older Windows versions do not support mDNS.

Connect your computer through ethernet to the same network as the Sofar EMS.
Make sure you have DHCP configured for the ethernet interface of your computer. (NOT a fixed IP address! See also )
Switch off WiFi on your computer (and 4G if you have that), and restart your computer so all network connections are cleared. After restarting, make sure all VPN connections are disabled.
Open a browser, surf to http://[SERIAL_NUMBER].local, where [SERIAL_NUMBER] is to be replaced by the serial number of your controller. For example,
It can take a minute for your computer to find the Sofar EMS.
If no connection can be made, you need to find the local IP address of the Sofar EMS. See option 3.

Initial configuration for a network without DHCP If you need to initially configure the controller in a network without DHCP, you can directly connect the controller to your computer (without a router) - and access it through mDNS.

Option 3: Access locally through the Sofar EMS's IP address.

Option 3.1: Find the IP address with an IP scanner (works if the Sofar has a good network configuration)

Download an IP scanner such as "Fing" ( or ) or "" (Windows).
Connect your smartphone or computer to the same network as the Sofar EMS.
Scan for devices on the network and find the IP address of the device with the MAC address listed on the Sofar EMS's label.

2. Accessing commissioning interface | Sofar EMS Documentation

In PowerShell, type: "Resolve-DnsName -Name [SERIAL_NUMBER].local", where [SERIAL_NUMBER] is to be replaced by the serial number of your controller. For example, "Resolve-DnsName -Name OM1241105ZEXO12B10A.local"
After a minute, the IP addresses of the controller should appear.

Powershell mDNS

Only the address of the type "A" (an IPv4 address) can be used to access to the commissioning interface, due to general restrictions in web browsers.
If your computer is in the same subnet as the Sofar, then you should be able to access the commissioning interface by surfing to the IP address in a web browser.
Else, first give your computer a fixed IP address in the same subnet as the Sofar before accessing the commissioning interface.
