Bringing legacy Zigbee + Z-Wave devices onto Matter — the bridges

“The point of Matter in my house isn't the replacement layer. It's the cross-ecosystem layer. Keep what works; let one device be visible to every controller at once.”

Picking the Zigbee stack — Zigbee2MQTT vs deCONZ vs ZHA

“If you're starting fresh in 2020: a CC2652 stick + Zigbee2MQTT. If you want a UI included: ConBee II + deCONZ. If you want zero add-ons: any supported stick + ZHA. The three are within 10% of each other on reliability; they differ on ergonomics.”

Glass-break and vibration sensors — the second-layer security

“Door sensors catch the opening. Glass-break sensors catch the breaking. The second one matters because the first one assumes the intruder walks in like a guest.”

ConBee + deCONZ — taking Zigbee off the SmartThings hub

“A radio you don't control isn't local-first, no matter where the automation logic runs. The SmartThings hub was a cloud account wearing a Zigbee antenna. The ConBee is just an antenna.”

Aqara Zigbee door/window sensors at scale

“Aqara door sensors are a third the size of a SmartThings Multipurpose, run two years on a single CR1632 button cell, and cost nine dollars each. The catch: they speak a slightly-off interpretation of the Zigbee HA spec, so the consumer hubs choke on them.”

Hue Motion sensor — Hue's first native automation device

“A motion sensor that's actually paired to its bulb ecosystem reacts in under 200 ms. Cross-ecosystem (SmartThings → Hue cloud → bulb) is 2-3 seconds. The difference is between 'magic' and 'frustrating'.”

Z-Wave vs Zigbee vs WiFi — a year on SmartThings

“Z-Wave for sensors, Zigbee for lights, WiFi for cameras. If you can't remember anything else from this post, remember that.”

SmartThings starter kit unboxing — first credible hub

“A hub with two radios, a rules engine, and a Groovy SmartApp platform is the first thing that makes a multi-vendor smart home tractable. Eighteen months overdue, finally here.”
