Decision point	myenergi harvi	Rainforest EAGLE 3

Install fit
Installation	Wall-mounted wireless CT sensor installed near CT clamps and within range of the myenergi master device.	Indoor plug-in gateway powered by included AC adapter; place near a router/Wi-Fi network and a utility smart meter with certified Zigbee HAN support.
Measurement	Wireless CT signal collector for grid, generation, or load monitoring in a myenergi system.	Gateway/data logger for utility smart-meter data and controllable-load monitoring; it does not directly measure current or energy with CTs.
Gateway fit
Connectivity	Wireless link to a compatible myenergi master device; harvi itself has no standalone IP gateway interface.	Ethernet, Wi-Fi, Zigbee Smart Energy utility HAN, Zigbee HA / Zigbee 3.0 control network, and HTTP REST API access.
Downstream protocols	Current-transformer inputs; harvi sends CT measurement signals wirelessly to compatible myenergi devices.	Zigbee Smart Energy Profile 1.1; Zigbee Home Automation 1.2; Zigbee 3.0; HTTP REST API; optional OpenADR 2.0b; SunSpec Modbus TCP control context.
Connected devices	3	10
Role	Energy-harvesting wireless CT sensor for myenergi zappi, eddi, and libbi systems.	Utility smart-meter gateway and building energy-management hub for streaming Zigbee Smart Energy meter data to apps, cloud services, and local integrations.
Monitoring
Protocol	868 / 915 MHz proprietary wireless telemetry	Ethernet / Wi-Fi / Zigbee Smart Energy / HTTP REST API
Local API	No	Yes
Cloud dependency	No standalone harvi cloud; app/cloud visibility depends on the paired internet-connected myenergi master device.	Cloud account/app is used for standard setup and remote monitoring; local HTTP REST API is documented, so the device is not cloud-only.
Home Assistant	Unknown	Yes
Solar fit
Solar import/export	Yes	Unknown
Buying context
Availability	UK / Ireland / Europe through myenergi official channels; local distributor availability varies by market.	United States / Canada utility-dependent smart-meter HAN programs; official US store route verified, with utility provisioning required.
