3 position switch

I have a pellet stove that has 3 heat settings, high, medium and low. There is a 3 position rocker switch on the stove that you use to manually select a setting. I would like to integrate it with my smartthings hub so I can select a setting while I am away. What is the simplest solution? I was thinking a fibaro smart implant. Installing a power supply will not be an issue.

The screenshot you’ve provided doesn’t list the details for the switch in question.

So sorry. The switch that I want to control is the one labeled heat output setting.
