How it works

The solution is based on Modbus TCP communication protocol. Waveshare Relay modules, with one exception, support  Modbus RTU (via RS485 port, 2-wires connection) and can be connected only via a Modbus RTU-TCP gateway (hardware converter).
The Waveshare POE ETH Relay modules with LAN port and support for Modbus TCP protocol - communicate with FIBARO and Yubii hubs without additional gateways or converters.

For Modbus RTU integration following gateways were tested and works fine:

• Waveshare: RS485 TO ETH (B), RS232/485/422 TO POE ETH (B), RS232/485 TO WIFI ETH (B) (www.waveshare.com/wiki)
• Elfin: EE11A, EW11A (www.hi-flying.com)

NOTE: the PUSR gateways we tested did not work properly with Waveshare Relay modules. Meanwhile, Waveshare announced new software for their modules (v2.0) with improved Modbus compatibility. The relay modules we tested, currently available on the market, had software v1.0. So just in case, we recommend Waveshare gateways for connecting Waveshare Relay modules.

Waveshare Relay integration is available as developer (multi-device) version implemented in the form of two QuickApps, and in a compact version in the form of a single QuickApp. The trial (demo) version is only available as the compact version.
For direct connection with the Waveshare POE ETH Relay modules (via Modbus TCP), it is recommended to use the compact version.
