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.
The recent move from Philips lead me to consider running everything through Home Assistant but I'm not ready yet. Configuring accessories and scene with Iconnecthue (especially splitting behaviors for week/week-end or during day) is too smooth and powerful). Also the Hue Bridge is rock solid, while my HA instance isn't. I could consider it if I were alone but i'm not. Maybe when I'll stop playing with HA and break things.
For the moment, using adaptive lightning on my Hue bridge controlled lights through HA is an incredible joy tho.
As it stands, I definitely understand your approach. Personally, I would also recommend any non-tech-savvy person or people who don't want to mess with it for a while to just use the Hue bridge with HA, if they were to try it out. The Hue bridge is really rock solid, no complaints there.
In case anyone else stumbles upon this and is curious, I'm now using a SONOFF Zigbee 3.0 USB Dongle and a Raspberry Pi and at least for me, the stability of the local Zigbee network is as good as it was with the Hue bridge before.
I didn't know iOS had a similar problem on the dev side, so I guess there's really no easy way out for mobile devs haha.
