I currently use a Wink Relay which incorporates 2 switches. One for the blower and one for the pump. I am converting everything to Iris, and have one GE switch on standby with another to buy. I will also have to go from single box to an old work 2 gang box, but definitely nice having schedule control and voice control with Alexa over the cooler.
I have a small cooler in my garage adn I use a Gen 1 smart plug.
