Wireless Zigbee Smart Button, 4-Way Remote Control Button Switch for Smart Home Devices, Scene Controller, Compatible with Tuya, Home Assistant, Homey, Hubitat, Requires Tuya Zigbee Hub

Apparently Lediary may use the Tuya backend. If that's true, it might be possible to get something like this Tuya hub that supports both bluetooth (fan's product details says it uses bluetooth) and Zigbee. https://www.amazon.com/MOES-Bluetooth-Gateway-Wireless-Support/dp/B0C3LPSXBM/ Then you could might conceivably be able to get a multipurpose Tuya-compatible Zigbee remote like this one, and link their programming all via the Tuya app. https://www.amazon.com/Wireless-Controller-Compatible-Assistant-Requires/dp/B0F1CJ6DHT/ That remote has a simple cradle you can stick on the wall next to your light switches. If it works, you'd assign the buttons to whatever fan/light functions you wanted. Assuming all the above is possible protocol-wise, a different way to connect it up would be via HomeAssistant. It would be more complicated and expensive, but if you wanted to dive into a whole-home smart home project, this could be your jumping off point. Good luck! 😄
