I still have a lot of the same stuff I bought, which falls into two main categories:
* Hue bulbs, which get active updates and are still maintained by Philips, and honestly are pretty good, if insanely overpriced, especially the HomeKit bridge
* "iHome" smart outlets which I belieeeeeeeve were once upon a time made by Belkin? They've ended support but the outlets themselves are very reliable, and pairable/managable entirely within the Home app so I barely noticed when they were discontinued. Picked up a 4-pack of them on fleabay recently for $20 and they work great still.
Mind you I'm not saying I'm great at this, if anything I'm lucky in that I really haven't had any smart home tech go poorly for me, apart from some other outlets that were some no-name brand. They're still kicking around my house but they need power cycles far more often than the iHome ones.
I would be interested in Hue, except Philips sold me an earlier iteration of a smart lamp which I loved for its ability to gently wake me up in the morning by slowly turning up the light. I love waking up without a loud alarm clock. In fact, I loved that so much I invested in a smart home hub to get Hue bulbs, and then Philips promptly bricked my original lamp. Unless I eventually bought a fancier home hub, which could grandfather it in!
No matter the convenience of a given smarthome feature, it will have to overcome the hurdle of all the time and money I invest in setting it up being liable to get vaporized at the click of a button from the supplier. Ultra frustrating experience, but one that instantly cured me of any romantic notions about the futuristic smart home.
