Zigbee Fan Buttons to connect to Home Assistant

I have an existing switch that simply controls load power to my fan. My fan has a smart controller in it (Sonoff iFan04) which is connected to Home Assistant.

I want to replace the existing switch with a zigbee device that controls the fan and light by communicating to Home assistant.

I found this, however, I need buttons to increase and decrease the fan speed.

Does anyone know zigbee buttons fit for this purpose?

I have one of these and it does the job.
