Texting percentage of full brightness is interesting. Let’s go with that one. Keep in mind, you’ll also be able to automate this using IFTTT time of day actions. I’ve already setup a template for changing the brightness, and I’ll share another later that uses this new feature you’ve requested.
Some other things to keep in mind — any new brightness commands will overrule the custom brightness, as will a power cycle. And I can’t stress how important a strong Wi-Fi signal is. 🙂
I’ll get on it this weekend. Follow up here when your adapter arrives and we’ll give it a shot.
