myenergi harvi vs Rainforest EAGLE 3

Install fit
Installation Indoor wall mounting near up to three CT clamps and within RF range of the paired master; use a suitable IP-rated plastic enclosure outdoors. 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 relay of CT-derived grid import/export, solar generation, battery, or load measurements; harvi is not a standalone IP meter or data logger. 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 Proprietary 868 MHz or 915 MHz low-power wireless link to one compatible myenergi master device; no Wi-Fi, Ethernet, or standalone IP interface. Ethernet, Wi-Fi, Zigbee Smart Energy utility HAN, Zigbee HA / Zigbee 3.0 control network, and HTTP REST API access.
Downstream protocols Up to three myenergi CT inputs for single-phase, three-phase, or multi-point measurement; wireless telemetry is sent to the paired zappi, eddi, or libbi master. 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 1 10
Role Battery-free energy-harvesting wireless CT sensor that relays grid, generation, battery, or load measurements to one paired myenergi master device. 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. Rainge cloud is used for standard remote monitoring; the local HTTP REST API still works on the LAN. Rainge has no Cloud API.
Home Assistant Unknown Yes
Solar fit
Solar import/export Yes Unknown
Buying context
Availability United Kingdom and Europe through myenergi channels; HARVI-65A3PR 915 MHz conformity is also published for Australia and New Zealand. Retail availability and radio variant vary by market. United States and Canada through Rainforest official stores; utility smart-meter HAN provisioning and compatibility are required.
