I Bought 27 Smart Home Devices in 18 Months. These 9 Actually Work Together.

A compatibility stack for first-time smart-home buyers tired of 7 apps and devices that don't talk to each other.

I spent $1,847 on smart home gear in 18 months. Returned 13 devices. The 9 that survived all run from a single app, work across Alexa + Google Home + Apple HomeKit, and haven't dropped offline in 4 months. Here's the full stack.

The discard pile is the lesson. Devices that needed their own app, broke on firmware updates, or couldn't be controlled outside their own ecosystem. The 9 in the stack solve all three.

If you're an Apple HomeKit purist, this stack has 3 brands that work with HomeKit. The other 6 don't. Be honest about your ecosystem before you download.

Not sponsored. Not a 'best of' list. The 9 devices I actually use, why each beat the alternative, and the brands I returned.
