Waveshare RS485 to Ethernet vs myenergi harvi

Energy Gateway

Waveshare RS485 to Ethernet

Waveshare RS485 TO ETH

Energy Gateway

myenergi harvi

Decision point	Waveshare RS485 to Ethernet	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.	Wall-mounted wireless CT sensor installed near CT clamps and within range of the myenergi master device.
Measurement	Gateway/data logger for RS485 device data acquisition and protocol conversion; it does not measure current or energy by itself.	Wireless CT signal collector for grid, generation, or load monitoring in a myenergi system.
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.	Wireless link to a compatible myenergi master device; harvi itself has no standalone IP gateway interface.
Downstream protocols	RS485 serial; Modbus RTU; Modbus TCP-to-RTU gateway; MQTT gateway; RS485-to-JSON; HTTP GET/POST; 645-meter protocol.	Current-transformer inputs; harvi sends CT measurement signals wirelessly to compatible myenergi devices.
Connected devices	30	3
Role	RS485 device data collector, serial server, and Modbus TCP-to-RTU / MQTT gateway for downstream meters, instruments, PLCs, and IoT devices.	Energy-harvesting wireless CT sensor for myenergi zappi, eddi, and libbi systems.
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.	UK / Ireland / Europe through myenergi official channels; local distributor availability varies by market.
