myenergi harvi vs Emporia Vue Utility Connect

Install fit
Phase support Unknown 2-phase residential service or light commercial 3-phase service, depending on the utility smart meter and HAN program
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 120 V outlet gateway near a supported AMI smart meter; setup uses the Emporia app and utility HAN registration.
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. Whole-home AMI smart-meter gateway with solar/net-metering visibility and roughly 30-second readings; no circuit-level CT measurement.
Meter fit
Current sensing Unknown No CT sensors; reads whole-home data from a compatible utility AMI smart meter over Zigbee Smart Energy Profile / HAN.
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. 2.4 GHz Wi-Fi 802.11 b/g/n to Emporia Cloud plus Zigbee Smart Energy Profile 1.1b / HAN to one supported utility AMI smart meter.
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 1.1b over the utility smart-meter HAN / AMI link.
Connected devices 1 1
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 HAN bridge that receives Zigbee Smart Energy data from a supported AMI meter and sends whole-home usage data to the Emporia app/cloud over Wi-Fi.
Monitoring
Protocol 868 / 915 MHz proprietary wireless telemetry 2.4 GHz Wi-Fi / Zigbee Smart Energy 1.1b / AMI smart meter HAN
Local API No No
Cloud dependency No standalone harvi cloud; app/cloud visibility depends on the paired internet-connected myenergi master device. Required for normal use: setup uses the Emporia app, and readings upload over 2.4 GHz Wi-Fi to Emporia Cloud. No official local API was verified.
Home Assistant Unknown No
Solar fit
Solar import/export Yes Yes
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 only; selected utility Zigbee SEP/HAN programs. Current Emporia sources list different program sets, so verify exact utility and meter eligibility.
