The Farmo Rain Gauge provides real-time, hyper-local rainfall data (measured in 1mm increments) directly to your phone, allowing you to monitor weather patterns across your entire property. Make more informed decisions on spraying, sowing, and stock movements without leaving the house. Don't rely on distant or unreliable BOM data to check rain levels. 
Cellular NB-IoT
IP67 Waterproof
1+ Year Battery Life (User Replaceable)
Email & SMS Notifications

Weather station data from the nearest BOM station is rarely accurate for your specific paddocks. The Farmo Rain Gauge is a robust sensor designed for hyper-local precision. Our patented single-spoon tipping design avoids the wear drift common in dual-spoon gauges, ensuring data readings stay accurate over time. The device uses long-range NB-IoT/Cat-M1 connectivity to transmit data from remote locations where standard mobile signals are weak. The rain gauge measures rainfall in 1mm increments and updates to your live feed every 15 minutes, giving you a live look at how much moisture is actually hitting the ground. 

Data Includes:

  • Rain Today (Running total for the day)
  • Rain This Month
  • Rain This Month versus closest BOM 30 year average
  • Rain This Year
  • Rain (Incremental increase throughout the day)

Alerts

  • Rain Today

Simply mount the rain gauge to a level post in a clear, open area using the included bracket. Once activated in the Farmo App, the internal tipping bucket mechanism begins measuring rainfall in 1mm increments. Data is transmitted to the Farmo App, where it is aggregated into daily, weekly, and monthly totals, providing you with comprehensive data across your property. The Farmo App also allows you to compare your rainfall against official long-term rainfall average records in your area. The Farmo App will find the nearest official weather station based on your rain gauge's location, giving you a reliable benchmark to measure your data against long-term trends.

Warranty

Farmo devices are covered by a 12 month back-to-base warranty. After the standard warranty period expires we apply a pro-rata warranty up to 24 months.


Care & Maintenance

Tipping spoon rain gauges are known as the most accurate of rain measuring devices, but they can be affected if spiders or ants get inside and build webs or nests. It depends on the location and the time of the year, but you should check every few months and apply preventive measures if required. Some customers use insect deterrent sprays effectively.

How Our Customers Use Farmo to Stay Ahead

Improve on data from a distant BOM station

Check exactly how many millimetres fell at a specific location on your property from your phone. Rainfall can vary a lot across properties and even between paddocks, so farmers use on-farm rain gauges to see what actually fell at their own site.

Improve Spraying Decisions

Check your paddock rain data to see if conditions are right for spraying. In orchards and vineyards, rainfall is a key trigger for many disease events. Remote automatic gauges are used as part of weather monitoring to assess infection risk and respond sooner.

Compare Data & Plan better

Compare your seasonal rain fall to the official long term average from the nearest BOM station and use these in sights to make earlier decisions around stocking rates, supplementary feeding, containment and selling stock.

Link to pump control and Irrigation scheduling

Use the Farmo App to link your rain data to a Farmo IoT Switch for irrigation or remote pump control. Automatic rain gauges help irrigators avoid watering after useful rain, fine-tune irrigation timing, and improve water-use efficiency.

The electric fence sensors and water rats have provided peace of mind knowing that the cattle are where they should be and with water in the troughs.
Great customer support when I experienced issues with fence sensors.

jeanette

I had a real problem getting accurate and up to date rain data on our farm in far east Gippsland when I spend most of the time in Melbourne. The rain gauge through Farmo solved the problem and the support and backup with questions was great

Mick

We have been using Water Rats for a number of years to monitor outlying or problem troughs. This has proven to be very successful giving peace of mind that water is available for cattle at the specified locations. We have had no issues with the flexiblity, reliability of the Water Rat. It is also helpful that we are linked in via Agriwebb.

malcolm

The "Water rat" is a simple unit that works well.
No installation. Easy to shift from one trough to the next.
Our unit stopped working, & Farmo promptly replaced it with a new unit, no hassles.

Michelle

Great tank monitoring system

Mitchell

Having a level meter on our water tank has meant so much to us in the last 12 months. There’s a huge sense of security in being able to detect unusual level changes, both monitoring the activity of our solar pump and also, during the dry season, the demand on our storage tank. Definitely a really worthwhile investment. Thoroughly recommend this little device.

James

Farmo has been great to deal with—excellent customer service and a team that genuinely cares. Their technology is simple to use and maintain, making it perfect for agriculture. Reliable, well-designed products and great support. Highly recommend!

Bryce

We had issues connecting with the WaterRat when we activated it but, working with customer service they quickly resolved the problem. The WaterRat was a cow life saver!! Our landowner, for some reason, shut the water off while we were away. The WaterRat alerted us when the tank was low and the device tipped on its side, with a stretch of 30+ weather it was worth its weight in gold!! Customer service is amazing!! I will be ordering more for all our pastures.

Dux

We use Farmo water rats in our troughs to keep an eye on the water levels . We can easily move them , as simple as taking them out and throwing them in the next trough as the cattle move paddocks . We can set alerts on our phones to let us know if a trough is empty . With tests they send the alert text within 10 seconds of tilting . They are very easy and cost effective.

FAQs

While the device typically reports status updates every few hours to save battery, it “wakes up” when it is raining, reporting every 15 minutes in 1mm increments. When it is not raining, the device sends a daily “heartbeat” to confirm it is operating.

No.  The unit has a pre-installed NB-IoT/Cat-M1 SIM card. It operates on the same long-range cellular towers used by your mobile phone, but with much better penetration. If you have even a basic mobile signal at the site, the device will connect.

No, the rain gauge will keep counting even when there is no connection. Once the connection resumes, the rainfall total will be updated on the next message sent.

The Farmo App allows you to compare your rainfall against official long term rainfall average records in your area. The Farmo App will find the nearest official weather station based on your rain gauge's location, giving you a reliable benchmark to measure your data against long-term trends.
