IMHO, IFTTT doesn't need developer mode, it is working throught mi cloud. On both my tablet and phone, developer mode remains ON, once I turned it on. And it is PER-bulb, i.e. you have to enable it for each bulb/light.

And I checked the code - the only thing I use kodi version for is for Ambi effect, but for normal discovery/on/off etc operation, it doesn't matter which version of Kodi it is. So, right now, Ambi wouldn't work on v18 (but it is easy to fix).
