Agricultural Weather Stations — South Africa
Ecowitt-based farm weather stations for South African farms, vineyards, orchards and remote sites. Monitor wind, rain, temperature and pressure — and add wireless soil moisture sensing to the same console.
Which Ecotao weather station also reads your soil?
All three — the HP2551CA, the WS6006CE and the HP2553CA — are full agricultural weather stations on their own, and every one of them can be expanded with a wireless WH51 soil moisture probe. The same 7″ console that shows you wind, rain and pressure can also show you root-zone moisture, without a second system to buy or learn.
Quick answer: choose the HP2551CA if your farm office has Wi-Fi, the WS6006CE if your field or borehole site has no Wi-Fi but has cellular signal, and the HP2553CA if you need a maintenance-free wind sensor and longer range for an exposed, dusty or coastal site. All three accept the same plug-in WH51 soil moisture sensor.
Three ways to monitor your farm's weather
Each kit is built around the same 433MHz Ecowitt sensor network, so the right choice comes down to your connectivity and site conditions — Wi-Fi, cellular, or a maintenance-free sensor for harsh environments.
A Wi-Fi connected station built around a standard cup-and-vane wind sensor and a compact solar-powered outdoor array. Reports to a 7″ colour TFT console with live graphing, trend alarms and a pressure-based weather forecast, and pushes that data straight to the internet.
- Wind sensingCup and vane type, 433MHz, up to 100m line of sight
- ConnectivityBuilt-in Wi-Fi, uploads to four pre-configured web services and apps
- Display7″ colour TFT, real-time graphs, trends and alarms, user calibration
- LoggingRecords min/max with date and time; 16MB onboard, expandable via microSD
- Update rate~16 seconds from the outdoor sensor array
- PowerSolar panel and supercapacitor outdoors; 5V/1A DC console, adapter included
- Soil add-onAccepts WH51 soil moisture, multi-channel temperature/humidity sensors
Where there's no farm Wi-Fi but there is a cellular signal, the WS6006CE runs as a completely standalone unit: solar and battery powered, logging locally and reporting over a 4G SIM rather than a router. Built to keep working unattended at an outlying field, dam wall or borehole.
- Connectivity4G GPRS/SMS with micro and nano SIM slots (SIM not included)
- PowerFully standalone, solar panel with battery backup on the outdoor array
- SensingSame 433MHz outdoor sensor array plus remote indoor humidity/temperature sensor, up to 100m line of sight
- LoggingCSV data logging to microSD/TF card; setup and download software included via USB
- AlertsUser-configured thresholds with SMS alarms or periodic SMS to up to three phones
- Soil add-onOptional WH51 soil moisture sensor
- NoteCellular data is metered — expect ~10-minute upload cycles on solar power to conserve SIM data
The same 7″ Wi-Fi console as the HP2551CA, paired with a solid-state ultrasonic anemometer instead of spinning cups, plus a separate large-capture rain gauge for finer rainfall resolution. With nothing mechanical to wear out in the wind sensor, it suits exposed vineyards, orchards and coastal blocks.
- Wind sensingUltrasonic anemometer, no moving parts, measures speed and direction
- Rain gaugeSeparate large-area gauge, 0.1mm resolution — better accuracy than integrated tipping spoon
- ConnectivityBuilt-in Wi-Fi, same four pre-configured web services and apps
- Range433MHz, extended to up to 200m line of sight
- Update rate~4.8 seconds for wind and weather data, ~48 seconds for rain
- Logging & power16MB onboard memory with microSD expansion; solar/supercap outdoor power
- Soil add-onAccepts WH51 soil moisture sensors on the same channel system

One console, both readings: weather above the canopy, moisture below the roots
Every console on this page runs on the same 433MHz sensor network used by the optional WH51 wireless soil moisture probe. Push one into the root zone of a block you're irrigating, pair it to the console, and its reading appears on the same screen as your wind, rain and temperature data — up to eight soil probes per console, so you can compare moisture across different blocks or depths at a glance.
If you need lab-style soil chemistry rather than just moisture, Ecotao also stocks dedicated soil instruments that pair well with a weather station programme — see the related instrumentation section below.
Where farm weather stations are used
Weather and soil monitoring supports decision-making across every stage of South African agriculture.
Vineyards & orchards
Track frost risk, wind events, and irrigation timing across blocks — especially valuable with the ultrasonic HP2553CA in exposed coastal vineyards.
Grain & row crop farms
Monitor rainfall accumulation and wind conditions to time spraying, harvesting, and planting decisions accurately.
Irrigation scheduling
Pair with WH51 soil moisture probes to irrigate based on actual root-zone conditions rather than a fixed schedule — saving water and energy costs.
Remote fields & boreholes
The WS6006CE's standalone 4G/SMS design keeps outlying sites monitored without any Wi-Fi infrastructure or daily site visits.
Livestock & dairy farms
Heat stress and storm alerts help farmers move livestock to shelter ahead of extreme weather events.
Homesteads & smallholdings
The HP2551CA's Wi-Fi connectivity and app integration make it an easy entry point for smaller properties with existing internet access.
