Water is scarce, power is dear, and the bakkie can't be everywhere.

Yes. Remote sensors, readers and water points use low-power devices with solar where there's no mains, so boreholes and far camps stay monitored.

Usually yes — we interface with existing pumps, VSDs, valves and pivot controls and add sensing where you're blind, rather than replacing equipment.

A reliable setup pairs buried multi-depth soil-moisture probes with a solar-powered weather station (rain, wind, temperature/humidity, solar radiation), both reporting over LoRaWAN to a gateway on the farm — so you get coverage across the lands without depending on cell signal in the field. Choose ruggedised, IP-rated devices with good lightning protection (the SA summer is hard on field electronics) and ICASA-accepted radios, feeding one dashboard that turns soil and weather data into irrigation decisions and alerts. The platform and data ownership matter as much as the sensors: insist on open APIs and your own data. addanode specifies, installs and runs the whole chain — probes, weather station, gateway and dashboard — as one supported system rather than a box of parts.
