But other than that, Mrs. Lincoln, how was the theatre?
Also, Home Assistant updates rarely break stuff (I haven't had anything break since I started with it two years ago), and you can always not update for a few weeks.
The uptime on my laptops is in years because nothing in OS updates are needed. If I'm not adding new hardware or exposing services to the public why would I need to update anything?
But go ahead and dicker with the technology as a hobby. Everyone needs one.
Because you might be using a web browser and/or email client to interface with the outside world...?
Yes, Home Assistant is not in the same ballpark at the moment but their all-in-one hardware bridge is actually a good point to get there in the long run. You can plonk that thing down, auto-discover all your Hue lights pretty much like in the Philipps Hue app and you're almost good to go. Scene and Room setup is a bit more cumbersome than with Hue but still doable.
I for one have moved all my Philips Hue lights to Home Assistant a while ago and never looked back. Everything runs a lot more stable, faster and I haven't had any issues with it. The only problem I've had in the past 12 months (even with regular updates) was my kitchen lights not turning on anymore and it turned out my Hue motion sensor there simply ran out of battery.
desktop/phone folks want the latest and greatest software and upgrade all the time, even automatically.
server folks want nothing to change ever.
second mindset is useful.
