Need wifi smart switch installation with Centsys D5 Evo (non-smart)

Hi there, I have a Cenysys (non-smart) D5 Evo Sliding gate motor and it has a Tuya Wifi Switch currently installed but it stopped working after 2 days of the motor installation. My router is a ORBI RB50 and I am unable to split the frequency to 2.4ghz so it is always 5ghz. It is unable to connect anymore and I am unable to pair with it. I need a new switch installed that will work with my gate motor so that I can control the gate via an app. Thanks
