Any solution for DC fans?

ifan03 works great with AC ceiling fans, but i have 2 DC ceiling fans in my house (3 wires).
what can i do to control them beside RF? i want something wifi or zigbee.
maybe some motor driver that can receive input from a esp module? or something that can be controlled by relays?

I’m by no means an expert, but it could be worth having a look at the shelly bits, they do a whole range of relays that are wifi.
