How do I know if my RF remote supports RM4 PRO?

1)Please check whether the working frequency is 433Mhz, please check the instruction or manual of the appliance; 2)Please check if it is a rolling code. If you are not sure, please contact the seller for inquiry.

Why can't I connect to WiFi?

1) The Wi-Fi signal is not 2.4GHz but 5Ghz or a 2.4G/5G mixed, and BroadLink can only support 2.4GHz WIFI; 2) The SSID and Password of the Wi-Fi exceed 32 characters or contain special characters (not ASCII)

How do I know if my Wi-Fi signal is 2.4Ghz or not?

It is recommended to check the router settings, usually the router's Wi-Fi settings will show the Wi-Fi relevant information.

My RF device frequency is 433MHz, my WIFI is also 2.4Ghz and my device learns successfully, but why is it not working?

Beacuse your original remote maybe rolling code which for security protection. Our RM4 pro only supports 433MHz fixed code RF signal devices.

Where can I get help if the product doesn't work?
