Best option for whole house attic fan

I have a belt driven whole house attic fan operated by a dumb high/low switch. Low down, off middle, high top.

I see some have used a regular Zwave GE switch, but that would allow only the high setting.

Anyone have any other ideas for a Zwave or Zigbee switch? Does anyone make something that would be low, high, off in Zwave or Zigbee?

Lots of conversations about this if you use the search function. Here’s a recent one:
