Smart-home hub blackout — Wh honesty
Keep the brains online — Zigbee / Z‑Wave coordinators and Home Assistant mini PCs are small continuous loads, but lights and locks only talk if the hub (and usually the LAN) stays up. Pair with Wi‑Fi / modem backup; distinct from security camera NVR stacks.
Hubs, radios, and HA mini PCs — what actually needs Wh
- Hub / coordinator draw is modest. Many Zigbee/Z‑Wave sticks + USB hubs, Hubitat / SmartThings class boxes, and HA Yellow / mini PCs idle ~5–25 W. The Wh problem is hours of continuous uptime, not surge.
- Cloud vs local. Cloud-only bulbs may still need ISP path for “away” scenes; local Zigbee/Z‑Wave + Home Assistant can keep local automations if the hub + LAN stay lit — but dead Wi‑Fi still orphans many Wi‑Fi bulbs. Size modem/router on Wi‑Fi / modem backup.
- Locks / lights / garage. Battery locks often keep working offline; motorized shades, wired switches, and some garage openers still need hub + power. Garage cycles: garage door opener honesty. Cameras/NVR are a heavier stack — security camera backup.
- Apartment / storm context. Renters: keep the hub kit shelf-sized and quiet — apartment blackouts. Multi-day storms: hub is cheap Wh compared with fridge/heat — prioritize in storm blackout kit.
- Vs NAS / home-lab: a dedicated Synology/QNAP lab often draws more continuous W than a lean HA mini PC — see NAS / home-lab blackout. Same graceful-shutdown habit if the host runs databases.

Smart-home hub Wh estimates
Hours ≈ (rated Wh × 0.85) ÷ load watts · hub alone is cheap; hub + Wi‑Fi is the real stack.
HA mini PC ~15 W
+ Modem / router ~20 W
Vs cameras / garage / NAS
Comparison: smart-home hub honesty
Filter by hub / LAN uptime fit — local radios still need the coordinator powered.
| Model | Wh · continuous AC | Hub / HA fit | Vs Wi‑Fi / cams / apartment honesty | Approx. USD |
|---|---|---|---|---|
| EcoFlow RIVER 3 Plus Compact | 286 Wh · 600 W | Easy overnight on ~15 W hub; add router before promising the day. | Fine apartment shelf kit — apartment. | ~$180–300 |
| Anker SOLIX C300 | 288 Wh · 300 W | Strong for coordinator-only; Wh soft if mesh + phones share the box. | Prioritize modem path — Wi‑Fi. | ~$200–280 |
| Jackery Explorer 1000 v2 Quiet | 1,070 Wh · 1,500 W | Comfortable all-day hub + LAN + light extras (estimates). | Quiet hallway placement — still not a camera farm — cams. | ~$499–589 |
| BLUETTI Elite 100 V2 | 1,024 Wh · 1,800 W | Similar ~1 kWh hub+router math — measure once. | Good mid path vs heavier NAS stacks. | ~$380–500 |
| Anker SOLIX C1000 Expand | 1,056 Wh → 2,112 Wh · 1,800 W | Expand when hub shares Wh with garage cycles / phones for days. | See garage opener · storm kit. | ~$400–600 |
| EcoFlow DELTA 3 Plus | 1,024 Wh · 1,800 W class | Hub load is trivial; leftover Wh for lights / fridge priority. | Storm kit hub — storm kit. | ~$600–900+ |
| BLUETTI AC200L Best headroom | 2,048 Wh · 2,400 W class | Overkill for hub alone; great shared house battery with cams + LAN. | Pair with cameras / apartment limits. | ~$800–1,100 |
