HomeKit IR Remote Control from Homekit

SO iOS 12 supposedly added IR remote code functionality, but I'm having trouble finding IR systems that are Home Kit compatible.

Not looking for anything too flashy. Basically want to be able to send IR codes to my AV gear and my LG air conditioner. Bonus points if I can have commands sent if my Ecobee4 hit's a certain temperature (it controls my heater, but can't control my wall AC unit).

https://www.simplecontrol.com Seems to be an option. Anyone have any experience with it?

Logitech still hasn't gotten their Harmony Hub compatible with Homekit yet.

Any other options out there?
