Review on Treatlife Smart Ceiling Fan Control: 4-Speed Switch, Works with Alexa and Google Assistant, Remote Control, Schedule, No Hub Required by Deejay Cowan

Enjoying life Manufactured by Tuya, a smart home controller manufacturer in China. The problem with these switches is that if you plug them into an AC powered ceiling fan, the switch will eventually kill your ceiling fan. The switch serves as a dimmer for the fan. This is how he regulates the speed. AC ceiling fans are not designed for use with a dimmer switch. The switch will eventually burn the ceiling fan motor. My ceiling fan motor burned out because of one of these switches. You can use these switches on fans with DC motors. The switch will not damage the DC motor. Tuya and concern for life nowhere tell you not to use this product with an AC ceiling fan motor.
