The year's smart-home themes — a cluster of PoE cameras feeding a small box with an AI accelerator, surrounded by a scatter of tiny DIY sensor boards — cameras everywhere, local object detection, and a wall of ESPHome sensors.

2021 in review — cameras everywhere, Coral landed. 2022 forecast.

End of year.

Scoring the 2020 forecast

PredictionConfidenceOutcomeVerdict
Frigate + multi-camera person-tracking80%Still on the 0.9 line; solid per-camera detection, but cross-camera re-id isn't here yet✗ (the tracking part slipped)
Matter / CHIP first dev spec80%Spec drafts circulating, SDK in dev, no consumer products yet✓ (partial)
Aqara hub replacement story65%Aqara M2 hub shipped; Aqara is loudly telegraphing Matter support
ESPHome on a dozen DIY devices90%14 ESP-based sensors deployed
Aeotec Garage Door Controller75%Installed October
Second + fourth PoE cameras85%5 PoE + 1 WiFi cameras now
Voice assistant fatigue formalized60%Amazon/Google did nothing
Wink finally folds for real70%Not a clean death — a 10-day outage in February, then a zombie limp-along nobody should trust✗ (close; it's abandonware, not gone)

5/8 + 1 partial = ~69%. The misses cluster on timing: the Frigate re-id and Wink's actual death are both "next year" problems.

Scoring the 2020 forecast: five hits (the Aqara Matter-ready hub, a dozen-plus ESPHome DIY sensors, the Aeotec garage controller, the second-through-fifth PoE cameras, and the Matter dev spec as a partial), and three misses (Frigate's cross-camera re-id still on the 0.9 line and not shipped, no voice-assistant-fatigue response from Amazon or Google, and Wink not cleanly folding — a February outage and a zombie limp-along rather than a real shutdown). About 69%; the misses are all timing, not wrong calls.

What got added

  • 5× PoE cameras (Reolink RLC-820A + RLC-822A + a Dahua VTO2311R PoE doorbell): porch, backyard, side yard, driveway, doorbell.
  • 1× WiFi camera (Reolink Argus 3): garage.
  • Coral USB Accelerator driving Frigate (on the 0.9 line) — the Coral is what makes five-plus camera streams of object detection run on a mini-PC without melting it.
  • Aeotec Garage Door Controller (Z-Wave, October).
  • 14× ESP-based DIY sensors (ESPHome firmware): SHT31 temp/humidity in 4 bathrooms + kitchen, PIR motion in 3 corner-rooms, plant moisture in 6 indoor planters.
  • Sonoff ZBDongle-E (December) — newer Zigbee coordinator, +50% range vs the ZBDongle-P. Migration planned for January.

The 2021 camera pipeline as a left-to-right flow. On the left, six cameras stacked — five PoE feeds (porch, backyard, side yard, driveway, and the doorbell) plus one Wi-Fi camera for the garage, drawn dashed to mark it as the odd one out. All six streams converge into the center box: Frigate on the 0.9 line, running on a mini-PC with a Coral USB TPU accelerator drawn as a labelled chip with pins. From Frigate a single arrow leads to Home Assistant on the right, which routes the results — a person fires a notification, a car or dog is ignored, and events are saved to the NVR. The caption makes the year's lesson explicit: one accelerator runs object detection on every stream locally.

Forecast for 2022

1. Matter 1.0 ships, first products by Q4. (Confidence: 75%) CSA's been steady. Q3-Q4 launch.

2. Frigate 0.12+ with proper face recognition. (Confidence: 65%) Optional, opt-in. Useful for "the kids are home from school" without GPS.

3. New-house build planning starts. (Confidence: 90%) We're outgrowing the current house. Going to plan a connected-from-the-walls-up build in 2022 with construction in 2023.

4. ESPHome continues exploding. (Confidence: 95%) 20+ DIY sensors by end of year.

5. Aqara Matter-bridge for existing Zigbee devices. (Confidence: 70%) Aqara has telegraphed it.

6. Home Assistant Yellow ships. (Confidence: 80%) HA-branded hardware. Buying one.

7. A "weather station" DIY project. (Confidence: 60%) ESP-based + a bunch of sensors. Outdoor temp / humidity / pressure / wind / rain. Replacement for the increasingly-unreliable home weather station I bought 5 years ago.

8. Tesla Powerwall integration. (Confidence: 50%) Considering solar + Powerwall for next house. If so, the Powerwall has a (semi-)open API that integrates with HA.

What I'm buying in 2022

  • HA Yellow ($150).
  • Another Coral USB if Frigate face recognition shipping.
  • 6-10 more ESPHome boards + sensors.
  • A real solar/wind/rain weather station if I can't DIY it well enough.
