Before you start setting up, your router must have DHCP enabled!

When you first turn on, you need to connect the controller to your WI-FI network. To do this, you must search for available networks on your smartphone or computer. The swr/pwr meter creates a network "SWRmeter_sn___" password "1234567890".

After connecting the network, go to the web browser at "http://192.168.4.1/wifi". A window with wifi settings will open. You must enter the name and password of your network and click "Connect / Disconnect"

After successfully connecting to your network, the access point «SWRmeter_sn___» will automatically turn off and the device will receive the IP address of your network. Further, to access the device's web server, use the IP address issued by your wifi router.

You can buy it on Ebay!
