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.	Indoor wall-mounted wireless CT bridge; protected outdoor use requires an IP-rated enclosure.
Measurement	Gateway/data logger for RS485 device data acquisition and protocol conversion; it does not measure current or energy by itself.	Wireless CT telemetry bridge for paired myenergi systems; not a standalone revenue meter.
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 myenergi low-power wireless link to paired master device; 868 MHz or 915 MHz by region. No Wi-Fi or Ethernet on harvi itself.
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 clamp inputs forwarded wirelessly to the paired myenergi master device.
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.	Battery-free wireless CT sensor and telemetry bridge for 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.	United Kingdom official myenergi store; broader myenergi installer/distributor availability varies by country, with wireless frequency/version fit depending on market (868 MHz or 915 MHz).
