Evaluate devices by installation fit, monitoring quality, data access, and whether they make sense in a real home after the hardware is installed.
IAMMETER WEM3080TD-150
A delta-system-focused three-phase Wi-Fi energy meter for sites that need open local integrations, import/export visibility, and better monitoring fit for 3-wire industrial or solar-adjacent loads.
IAMMETER WPC3700
A single-phase Wi-Fi power controller for resistive loads that helps solar homes turn surplus PV into useful hot-water or heater demand instead of exporting it to the grid.
IoTaWatt Monitoring Pro Kit V6.4
A local-first 14-input Wi-Fi energy monitor kit for homes and small sites that want circuit-level CT monitoring, solar import/export modeling, and Home Assistant-friendly local data.
KOSTAL Solar Electric KOSTAL Smart Energy Meter - G2
A three-phase KOSTAL energy meter and energy-management accessory for PLENTICORE and related KOSTAL inverter systems, used for real-time consumption/generation measurement, self-consumption optimisation, dynamic active-power control, and battery or wallbox workflows inside the KOSTAL ecosystem.
Leviton LWHEM-2
A panel-based whole-home energy monitor for households already leaning into Leviton's smart load center ecosystem and wanting one app for mains visibility, smart-breaker control, and backup-aware load management.
Leviton LWHEM-2 / LWHEM-2R
A panel-integrated whole-home energy monitor for Leviton load-center households that want real-time grid and alternate-source visibility inside the My Leviton ecosystem rather than a separate clamp meter and third-party app stack.
myenergi harvi
A compact wireless CT bridge for myenergi ecosystems that helps solar and EV households add grid, generation, or battery sensing without running extra CT wiring back to the main control device.
myenergi libbi
A modular myenergi home battery system with 5 kWh building blocks, a 3.68 kW or 5 kW single-phase hybrid inverter, solar and grid charging modes, and tight coordination with zappi, eddi and the myenergi app.
myenergi zappi
A solar-first home charger with strong surplus-energy modes and home-energy ecosystem integration, best suited to households that actively want to soak up midday solar rather than just charge overnight.
OpenEnergyMonitor emonPi3
An open-source, local-data-friendly 6-channel CT energy monitor with integrated Raspberry Pi and emonCMS for households and advanced users who want flexible monitoring across consumption, solar, EV charging, batteries, and heat pumps.
OpenEnergyMonitor emonTx6
A six-channel wireless energy-monitoring expander node for OpenEnergyMonitor systems, designed to add CT inputs in another panel or building area and send readings to an emonPi3 or emonBase.
Refoss EM16P
A local-first 18-circuit CT energy monitor for Home Assistant households that want whole-home, branch-circuit, and solar/feed-in visibility.
SAJ B2 HV Series
A modular high-voltage home battery for solar households that want IP65-rated outdoor flexibility, 90% DoD usable capacity, and a clean path from 5 to 25 kWh nominal storage.
SAJ R5-5K-T2
A single-phase SAJ inverter aimed at straightforward residential installs where compact hardware, app-based monitoring, and a simpler shortlist matter.
Schneider Electric WISEREMZ
A panel-installed home energy monitor for split-phase households that want real-time usage visibility, app-based alerts, and a practical starting point for Schneider's broader connected-home load-control ecosystem.
Sense Sense Home Energy Monitor
A U.S./Canada split-phase whole-home energy monitor that installs in the electrical panel with clamp-on current sensors and uses the Sense app to identify real-time household energy use patterns.
Shelly Shelly 3EM
A three-phase Wi-Fi energy meter for households and small facilities that want circuit-level monitoring, solar-aware import/export visibility, and useful local control options without moving to a full DIN-rail meter stack.
Shelly S3EM-003CXCEU63 / Shelly 3EM-63T Gen3
A compact Shelly Gen3 three-channel energy meter with flat terminals, 63 A per-phase monitoring, local Wi-Fi access, photovoltaic-ready four-quadrant measurement, and strong Home Assistant fit for homeowners or installers who want circuit, three-phase, or solar import/export visibility without a separate hub.
Shelly EM
A practical single-phase energy monitor for homeowners who want an easier retrofit path, better Home Assistant fit, and clearer visibility into whole-home use or a couple of important circuits.
Shelly EM Gen3
A compact retrofit monitor for single-phase homes that want real-time circuit visibility and stronger local-integration options than many app-only consumer monitors.
Shelly S4EM-001PXCEU16
A compact 16 A inline smart energy meter for monitoring a single appliance or small circuit, with Wi-Fi, Zigbee, Bluetooth, Matter, local web/API access, MQTT/HTTP/WebSocket support, and optional Shelly cloud features.
Shelly Shelly Pro 3EM
A DIN-rail three-phase energy meter for solar homes and small sites that want stronger local data access, panel-level visibility, and better fit for PV, EV, or automation-heavy monitoring than a simpler app-only monitor usually provides.
Shelly Pro 3EM 120A
A modern three-phase Shelly meter for larger homes, workshops, and solar-heavy households that want whole-home visibility with strong local networking and automation options.
Shelly Pro 3EM-3CT63 / SPEM-003CEBEU63
A DIN-rail single- or three-phase energy meter with a combined 63 A three-phase current transformer, LAN/Wi-Fi connectivity, local automation protocols, and photovoltaic-ready 4-quadrant measurement.
