Replace 4-position 3-speed fan switch with wireless control?

I have a 4-Position 3-Speed fan selector rotary switch similar to the pictures below. It's mounted on a wall plate so that I can select the speed of my HVAC fan. I was wondering if there are any wall-mounted wireless devices on the market that I can replace this with so that I can control the fan speed remotely? The typical smart thermostat doesn't cut it since they are not meant for line voltage and are only single-speed.

Background: My overall goal is to redo how my HVAC system was set up in my condo. It's a water-cooled AC system where the cooling is controlled by my thermostat (opens and shuts a valve controlling the cooled water) but the fan motor is a separate manual rotary knob located in another part of the home. It's always been a pain to remember to turn on or off the fan when the AC is on or off and also when I want to change the fan's speed. I'd like to try to automate the system so that I can turn the AC and fan on/off wirelessly and simultaneously.

Not sure what you have going on there but line voltage thermostats can control water flow and a fan.
It's east to automate but not wirelessly.

There isn't anything that will replace that fan speed for remote control but you can interrupt power to it. Just pick a speed manually.
