How to Build a Farm Monitoring System with the Sensors and Software You Already Use
Most farms already own more sensors than they realise: a weather station, grain store cables, a milk tank controller, EID readers and machinery telematics. This guide shows how to join them into one farm monitoring system: audit what you own, get data out through APIs, Modbus, MQTT, exports or alarm relays, connect over LoRaWAN and 4G, choose between Home Assistant, Node-RED and Grafana, set alerts from AHDB and milk-cooling thresholds, and budget with a worked example (£5,370 in year one, £6,810 over three years) and FETF 2026 reference prices.
