Everything I’ve had over the years is homekit related. I purchased a HomePod mini for the thread integration and then on offer on prime last year and this year updated a few plugs sensors and climate from eve for the thread router to extend around the house. It’s a mis mash of older homekit and new thread, it all seems to work until recently when an eve update knocked everything out so had to unplug all my HomePods ands Apple TV, basically anything that could be a Homebase to try and reset. (I never knew to try this until eve support told me, I was resetting individual devices thinking it was them only)
The eve thread devices now have the option of an upgrade to matter in the app and I honestly don’t think I want to go through all the hassle as you just no it’s going to break the system.

Maybe later on I’ll change them over when there’s improvement, but there really is no point unless I wanted to use them on another system or sell them.

Don’t switch to Alexa, despite the obvious privacy issues with Amazon, the whole interaction is painful. And the incessant “By the way, you can do this or buy on Amazon” and so on are cringe. I switched to Apple’s HomePod and although it’s also flawed, it’s been. Much nicer experience. Plus you can use a Raspberry Pi with HomeBridge running on it to make Home interact with any wifi smart thing. The Pi converts them into Apple compatible devices. It also has many plugins to create intricate automations by creating dummy sensors to trigger things and so on. It’s really powerful.
