After reading about Hubitat and watching some videos I have no doubt it is exactly what I need (kudos for its creators and the development team).
However, in my personal opinion it is lacking on UX.
Reading through some posts I noticed you can customize appearance with CSS, my question is: "How far can you go"?
User interface, looks and experience are subjective but while some people love their nuclear plant control center looking dashboards (no offense, it is actually cool ), I think if I'm going to place tablets around the house in kiosk mode I need something clean, minimalist, intuitive, with a clean purpose so not only guests, wife and kids can take advantage of it but it also can complement my house.
I can't post links or images (maybe because it is my first post?) but the Home Assistant community has this awesome project with is clearly based on apples Home app and if you are "cloning" Apple you can't go wrong considering the amount of money they put towards user experience and research (just google "A different take on designing a Lovelace UI" to see it)
Atmos home is another perfect example of a nice and clean UI but unfortunately they are not in a rush to release it.
On top of the above think about the UI in your Ecobee and Nest thermostas, that is what I'm referring too. It is a modern and clean experience suitable to everyone and everywhere.
I could go on but you get the point.
I guess my questions are:
Are there any similar community projects for Hubitat or alternative dashboards more inline with what I'm looking for?
Can I achieve this by tweaking the CSS on the original dashboards (I would have no problems doing it myself)?
If answer to previous questions is no, does it provide a rest API and webhooks? If it does I wouldn't mind creating an web app myself but I would need to interact with devices and somehow get their status back (preferably through a webhook instead of pulling with a timer).
