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-65A3PR / HARVI-65A3PR-A
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.
OpenEVSE Advanced Series 48A Level 2 - SAE J1772 (Assembled)
An open-source 48 A Level 2 AC EV charger for buyers who want local control, adjustable current, MQTT/OCPP integration, and solar-aware automation instead of a closed app-only charger.
Rainforest Automation EAGLE 3
A utility smart-meter gateway that brings Zigbee Smart Energy meter data onto a home network for app, cloud, and local API based monitoring.
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 three-phase 5 kW grid-tied residential string inverter with two MPPT trackers, a 7.5 kWp maximum PV-array rating, IP65 wall mounting, optional remote monitoring, and documented local communication paths.
Schneider Electric A9MEM2455
A compact single-phase, direct-connected 100 A DIN-rail energy meter for submetering, cost allocation, and bidirectional import/export measurement over local RS-485 Modbus.
Schneider Electric A9MEM3155
A MID-certified, direct-connected 63 A DIN-rail energy meter for single- and three-phase submetering. The iEM3155 combines Class 1 / Class B active-energy accuracy, signed four-quadrant metering and local RS-485 Modbus RTU for distribution boards, billing evidence and building-management integrations.
Schneider Electric A9MEM3255
A Class 0.5S, MID-certified CT-operated DIN-rail meter for high-current submetering, solar import/export measurement and local RS-485 Modbus integration.
Schneider Electric METSEPM5560
A high-accuracy panel power meter for commercial and industrial submetering, power-quality visibility, and solar import/export monitoring, with local Ethernet and RS-485 connectivity instead of a required vendor cloud.
Shelly S4SW-001P8EU
A compact single-channel smart relay with direct power and energy measurement for lights and small appliances up to 8 A, suited to wall-box retrofits where local control and Home Assistant support matter.
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.
