Waveshare RS485 to Ethernet vs myenergi harvi

Install fit
Phase support Not phase-specific; depends on connected RS485 meter or inverter Unknown
Installation DIN-rail mounted RS485-to-Ethernet gateway powered from 9-24 V DC screw terminals. 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.
Measurement Gateway/data logger for RS485 device data acquisition and protocol conversion; it does not measure current or energy by itself. Wireless relay of CT-derived grid import/export, solar generation, battery, or load measurements; harvi is not a standalone IP meter or data logger.
Max current 0 A Unknown
Gateway fit
Connectivity 10/100M RJ45 Ethernet; local web browser and host-tool configuration; TCP server, TCP client, UDP, UDP multicast, DHCP, and DNS support. Proprietary 868 MHz or 915 MHz low-power wireless link to one compatible myenergi master device; no Wi-Fi, Ethernet, or standalone IP interface.
Downstream protocols RS485 serial; Modbus RTU; Modbus TCP-to-RTU gateway; MQTT gateway; RS485-to-JSON; HTTP GET/POST; 645-meter protocol. 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.
Connected devices 32 1
Role RS485 device data collector, serial server, and Modbus TCP-to-RTU / MQTT gateway for downstream meters, instruments, PLCs, and IoT devices. Battery-free energy-harvesting wireless CT sensor that relays grid, generation, battery, or load measurements to one paired myenergi master device.
Monitoring
Protocol RS485 Serial Server / Ethernet / Web Configuration 868 / 915 MHz proprietary wireless telemetry
Local API Yes No
Cloud dependency No vendor cloud is required for local Ethernet, VCOM, web configuration, TCP/UDP, or Modbus TCP-to-RTU use; MQTT/HTTP/cloud upload modes are optional. No standalone harvi cloud; app/cloud visibility depends on the paired internet-connected myenergi master device.
Home Assistant Yes Unknown
Solar fit
Solar import/export No Yes
Buying context
Price range About $20-$40 Unknown
Availability Global via Waveshare official store/product page; local reseller stock and version availability vary by region. 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.
