IRIV IO Controller Series: RS-485 (Modbus) → Ethernet → Cloud (Blynk / ThingSpeak / MQTT) + Agricult
Read RS-485 Modbus sensors on IRIV, send data via WIZnet W5x00 to Blynk, ThingSpeak, and MQTT (Adafruit IO), then build an irrigation automation example.

Project description
This series shows how to read RS-485 (Modbus RTU) sensors on the IRIV IO Controller and send data over Ethernet using a WIZnet W5x00 driver (CircuitPython) to three cloud paths—Blynk, ThingSpeak, and MQTT (Adafruit IO)—and then apply it to an agriculture automation example (moisture-based pump control).
