Meross's $160 Apple Home Panel Monitor Tracks 18 Circuits and Beats Sense by Three Circuits Per Dollar

What it is

The Meross 18-Circuit Electrical Panel Monitor is a whole-home energy monitor that installs inside a residential breaker panel, clamping 18 separate current transformers around individual circuits to report per-circuit wattage and cumulative kWh via Apple Home, Google Home, Amazon Alexa, and Matter. Core specs: 18 CT clamps rated up to 200A main service, 5 mA resolution on individual circuits, 1-second sample rate with Wi-Fi 2.4 GHz upload to the Meross cloud, Apple Home energy monitoring integration (see live usage by circuit in the Home app), Matter-over-Wi-Fi certification, iOS/Android companion app for historical graphs, automation hooks (trigger other HomeKit/Matter devices based on circuit load), and a compact 6 by 4 by 1.5-inch hub that mounts inside or beside the main panel.

Pricing: $159.99 current sale at Meross direct and Amazon, down from $199 list. Install requires a licensed electrician for anything beyond opening the panel; Meross does not ship UL listing for DIY panel work.

What's interesting

The 9to5toys launch coverage framed the Meross as "Sense at half the price, with Apple Home baked in." That's accurate on both axes. Sense ($299) monitors only the main 240V trunk and uses ML to infer what's running. Meross measures 18 circuits directly, so attribution is exact rather than probabilistic. For power users, knowing that circuit 7 (kitchen island) pulled 2.4 kWh over 24 hours is more actionable than Sense's inferred "dishwasher ran 3 times."

Apple Home energy monitoring is the standout integration. The Home app on iOS 26 displays live wattage per circuit as tiles, graphs, and automation triggers. Users can write a Shortcut like "if laundry-room circuit draws more than 1,000 W for 30 minutes, send a notification" for dryer-done detection without any third-party app.

Matter-over-Wi-Fi means the same device reports to Google Home and Alexa simultaneously. For multi-ecosystem households, one install covers everyone.

The 18-circuit count covers most residential panels directly. Typical US homes have 20 to 42 circuits; a 200A panel commonly has 16 to 24 breakers in the busy-circuit tier (appliances, kitchen, laundry, HVAC), with the remainder being lighting. The Meross 18-clamp count maps well to "all the circuits you'd care about."

Historical data is stored in the Meross cloud for 2 years free. For utility-bill reconciliation or identifying energy vampires, 2 years is enough to catch seasonal patterns. Export to CSV is available in the app.

What's missing or unverified

Licensed electrician required for installation. Meross lists this clearly and the 9to5toys coverage repeats it. DIY panel work voids the device warranty and typically violates local electrical code. Expect an installer to charge $150 to $300 for a 60-to-90 minute install.

Only 18 circuits. Homes with 30+ active circuits will need to prioritize which circuits get clamped. Some users run two Meross units side by side (36 circuits total, $320) to cover everything.

Wi-Fi 2.4 GHz only. Meross does not support 5 GHz Wi-Fi or Ethernet. For homes with weak 2.4 GHz coverage at the panel (often in garages or basements), signal strength is the first troubleshooting check.

Cloud-dependent for historical views. Local fallback works for live Apple Home tiles but historical graphs require Meross cloud uptime. If Meross shuts down the cloud service in the future, the device becomes a live-only appliance.

Current transformer accuracy is rated at ±2% above 0.5 A. Very low-current devices (LED night lights, standby electronics) may read as 0 W even when pulling small loads. For whole-home kWh tracking, the rounding error is negligible; for individual low-load device identification, Sense's ML approach finds subtle loads that Meross's CT clamps don't.

Meross's track record is mid-tier. The company has shipped HomeKit accessories since 2018 but has had occasional firmware regression issues on garage door openers. The panel monitor is a newer product line; long-term stability is less proven than Sense (category leader since 2015).

Against Sense Home Energy Monitor at $299 (ML inference, 1 device monitors whole home), Emporia Vue Gen 3 at $119 (16 circuits, no Apple Home), and Shelly Pro 4PM (per-circuit relays plus metering, $89 per 4 circuits), the Meross wins on Apple Home integration and circuit-count-per-dollar; it loses on ML sophistication (Sense) and switching capability (Shelly).

Who it's for

Apple Home-first households who want per-circuit energy data inside the native Home app without third-party monitoring services. Electricians and energy-conscious owners who want direct CT clamp accuracy over Sense's ML inference. Matter households standardizing on Apple plus Google plus Alexa where any one device should report to all three. Larger homes where 18 circuits covers the consumption-heavy breakers.

Not for: DIY electrical phobes (professional install required), renters who cannot modify the panel, very large homes needing 30+ circuits without adding a second unit, or households committed to Sense's ML disaggregation.

Verdict

The Meross 18-Circuit Electrical Panel Monitor at $159 (sale) is the right pick for Apple Home households that want accurate per-circuit energy data without paying Sense's $299 premium. Apple Home integration, Matter support, and 18 direct measurements make it more actionable than ML-inference alternatives. Against Sense (pricier, ML-inference), Emporia Vue Gen 3 (similar circuits, no Apple), and Shelly Pro 4PM (per-circuit control, more modules needed), the Meross wins on Apple-native energy data at this price. For target Apple-household buyers, this is the right pick.
