If one device to control two fans is important, you could look in to Bond. It’s only an indirect integration with IFTTT I believe, but there’s an active thread in this forum.
So my husband stumbled across the Bond Remote Controller. I had to share it. This hub takes your existing remote controlled ceiling fans and makes them smart without any rewiring or the need to purchase z-wave switches for the fan and light. It’s an RF blaster that is programmed using the existing RF or IR remote. They claim integration with SmartThings. It’s set to ship out on Nov 16th and says it’s $99 bucks. To outfit one fan with a fan/light switch individually, iteiukd be about $90 bucks!! For just 1 set of switches. So for about the same price, you can control them all.
