Is it possible to tell my ecobee to turn on or off the HRV from homey pro?

Hi,

I have an ecobee thermostat with numerous sensors in various rooms.
I currently have the ecobee setup to run the HRV 10 minutes every hour, but I really only want it to run the fan and HRV when there is a big enough temperature differential between the basement (where the furnace is) and the top floor.

I would also like to set up homey to turn off the HRV when we put the house into vacation mode. (I have a virtual device that I use for vacation mode).

I would be happy to use Homey Script if that is the only way to do it.

Thanks
