HAUTENSE
LAUNCH SERIES Fence monitor · LTE-M
HAUTENSE

She saw it.
She called.

Hautense sits on the wire and measures your fence voltage around the clock, day and night. Power's gone — fallen branch, tall grass, broken wire, dead energizer? A real phone call lets you know. Before your animals find out.

How it works

The monitor measures. When the fence fails, she calls.

No app to fiddle with for an hour, no hub to pair. Three simple moves, and the lookout starts her watch.

STEP 01 01

Clip the monitor onto the wire

It sits on the fence, at a post, in a few minutes. One clamp on the wire, one ground stake, a single button to switch it on — no wiring at the energizer.

STEP 02 02

She measures the voltage around the clock

Every pulse is read and put into kilovolts — 8.2 kV. You follow the voltage in real time, sent over LTE-M, no Wi-Fi.

STEP 03 03

When the fence fails, she calls you

Voltage dropping or no power at all: a voice call, SMS and notification.

At the post

She stands her watch
right where your animals are.

The clamp on the wire, the ground stake, one button — and the lookout watches the voltage day and night. No hub, no Wi-Fi: just the pasture, the fence and her.

INSTALLED IN MINUTES NO WIRING
What the lookout detects

Four classic failures. Not one gets past her.

An electric fence rarely dies all at once: it weakens, then goes out. Hautense reads the voltage and warns you the moment it slips — here are the failures we see most out in the pasture.

Branch down on the wire

A gust of wind, a branch lying across the fence: the voltage collapses along the whole field.

LOW VOLTAGE2.8 kV

Grass grown too tall

The grass climbs, touches the wire and shorts the fence to earth. The power leaks away — and rain only makes it worse.

LOW VOLTAGE3.4 kV

Broken wire

Wildlife, machinery, wear: past the break, nothing stings anymore. And the herd always works it out eventually.

NO VOLTAGE0.4 kV

Dead energizer or battery

The energizer stops or the battery gives up: not a single pulse goes out. Without a lookout, you find out too late.

NO VOLTAGE0.0 kV
IN R&DAutomatic recognition of the failure type — branch, grass, break — powered by artificial intelligence. Currently in development.
OFFLINE And if the monitor itself loses signal or runs low, you're warned too. The lookout even reports on herself.
The monitor

A field-grade monitor, not a gadget.

Self-powered, no-nonsense, built to stay outdoors all year at the far end of the pasture — where Wi-Fi has never set foot.

The voltage, measured  around the clock

Every pulse is read on the wire and converted to kilovolts, from 600 V to 20 kV. Instant alerts and remote monitoring. 

LTE-M — no Wi-Fi, at the far end of the pasture

The monitor has its own low-power cellular connection — LTE-M / NB-IoT, over 4G networks. No hub, no pairing.

Built-in solar panel

It recharges in the sun and runs about 2 months without a single break in the clouds on its buffer battery. You're warned long before it runs out.

Clips onto the wire in minutes

Works with off-the-shelf energizers — mains, battery or solar. No changes to your installation.

A real call, not a lost notification

When the fence fails, your phone rings. A voice tells you which fence and what voltage. SMS and notification on top.

The app · included

Your fences, as curves.

Android and iOS app included, no subscription. Follow each fence's voltage live, read the curves day after day, and set the threshold that triggers the call yourself.

Voltage curves

Every fence, reading after reading. You spot a slow decline long before it becomes a failure.

Adjustable alert thresholds

You set the voltage below which Hautense should call. One threshold per fence, changeable at any time.

The alerts

A granny on the line.

The lookout never sleeps and she loves her telephone. When the fence fails, she doesn't wait for you to think of opening an app.

A real voice call

Your phone rings, a voice tells you which fence is affected and the voltage it read. She repeats the essentials — you often pick up mid-job.

SMS

The essentials in writing, to keep a record and forward to the neighbour who's keeping an eye on things while you're away.

Notification + history

Each fence's voltage feed, up to date in your pocket. And an alert when everything is back to normal — power restored, monitor back online.

Feedback from the field.

A deer must have charged into my fence and a wire was touching the post. I would never have spotted it without this!

The call is what changes everything, so handy — I have it ring the landline and it leaves me a voicemail.

Hautense keeps watch — she doesn't herd your animals.

The monitor watches the fence voltage; it replaces neither regular inspection of the line and posts, nor the keeping of the animals, which remain the farmer's responsibility. No alert system can guarantee transmission in all circumstances (network, battery, the unexpected). See our terms of sale and liability limits.

Frequently asked questions

Everything people ask us.

Do I need Wi-Fi or an Internet router?+
No. The monitor carries its own LTE-M cellular connection, designed for connected devices in rural areas. It works at the far end of the pasture, where your router has never set foot.
GSM or LoRaWAN version — which should I choose?+
The GSM version works straight out of the box, with no gateway at all: SIM included, 25 alert calls and SMS, free push notifications, optional GPS and anti-theft motion detection. The LoRaWAN version (EU868 MHz, SX1262 radio) is for those who want a sensor on a LoRaWAN network: add an Awaro Wi-Fi gateway — handy for several sensors in the same area — or use your existing LoRaWAN infrastructure. The housing and the measurement are identical on both versions.
What if mobile coverage is weak at my place?+
The monitor uses LTE-M / NB-IoT — low-power 4G networks that carry further and cut through terrain better than everyday 4G. We check the coverage of your land before shipping; if it doesn't get through, we refund you.
Is it compatible with my energizer?+
Yes, whatever the brand: mains, battery or solar. The monitor reads the voltage on the wire — it doesn't plug into the energizer. No changes to your installation.
What's the battery life?+
The monitor is powered by a solar panel and runs about 2 months without sun on its buffer battery. You get a low-battery alert well before it shuts down — the lookout reports on herself too.
How am I alerted when the fence fails?+
A real voice call first, then SMS and notification. The voice tells you which fence and what voltage. The GSM version includes 25 alert calls and SMS; beyond that, a top-up credit, no monthly subscription.
Is there a subscription?+
No, no monthly subscription. The 4G SIM card, the app and 25 alert calls + SMS come with the GSM monitor. Beyond that, you top up a credit — you only pay for what you use. The app and notifications stay unlimited.
What do you do with my data (GDPR)?+
Your voltage readings belong to you. Hosted in the EU, never sold. You can export or delete your data whenever you want.
When will it ship?+
The launch series ships at launch (date to be confirmed). Your pre-order takes no payment now: you confirm when it ships.

“She saw it. She called.”

If the power's gone, you'll know before your animals do. The lookout starts her watch the moment you switch her on.
