Email & SMS Notifications

An unwanted open gate can be a costly problem, and with gates spread across a large property, you can’t be everywhere at once. Whether it's a gate left open after a delivery, an unauthorised visitor, or livestock finding their way through, the consequences can be serious. The Farmo Farm Gate Sensor is a wireless monitoring solution designed specifically for Australian farm conditions. Using a ferromagnetic sensor that detects the metal drop latch in the closed position, it sends the gate status directly to the Farmo App. 

Data Includes:

  • Open/Closed Status

Alerts:

  • Gate Open
  • Gate Closed

Installation is as simple as replacing your existing drop latch with the Farmo Gate Sensor and reattaching the gate chain as normal. The sensor detects when the metal latch is no longer in the closed position and immediately transmits a customisable alert over the built-in cellular network to the Farmo App. Once activated, you'll receive real-time SMS or email notifications whenever a gate opens or closes, and a full timestamped history of all gate activity is recorded in the app. No wiring or special tools, just a five-minute retrofit that works with most common Australian gate designs.

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

The Farmo Gate Sensor is designed to retrofit most common Australian farm gate designs. It replaces your existing drop latch and uses the same gate chain.

Yes, as long as there’s mobile network coverage (Telstra by default) the device will work. Data is sent over the specialised long distance CatM1/Nb-IoT part of the 4G and 5G networks, so you will find coverage goes further than voice calls on handsets.

The sensor uses a ferromagnetic detection method, meaning it specifically detects the presence or absence of the metal drop latch in the closed position. This makes it far more reliable than motion-based alternatives, which can trigger false alerts from wind, animals, or vibrations.

The lithium battery will last for over a year before needing replacement. Battery status is visible in the Farmo App, and when required a new battery can be ordered from Farmo and installed by the customer.
