Real-time temperature monitoring

The cold room fails at 3 a.m. You find out before the loss.

Kelvo tracks your cold rooms around the clock and fires the alert the second something drifts out of range — via WhatsApp, phone call, Telegram, SMS or email.

Simple setup. No construction. Works on any cold room or freezer.

The cost of not knowing

When the cold room fails, nothing warns you. Until you open the door.

One night with the compressor down is enough to lose the whole stock. By the time you notice, the loss has already happened.

Stock lost

Meat, dairy, ingredients and kegs spoil within hours outside the ideal range. A single event costs more than years of monitoring.

Found out too late

The failure almost always hits at night, on weekends, or with the place closed — exactly when no one is watching the thermometer.

No log, no proof

Writing temperatures on paper is fragile and easy to forget. When an inspector asks for the history, it has to exist.

How it works

From sensor to your phone in three steps

No expensive hub, no on-site technician. Install it, connect Wi-Fi, and see the temperature right away.

01

Install the sensor

Place the Kelvo sensor inside the cold room or freezer. It joins your Wi-Fi in minutes — no construction, no wiring.

02

Set your limits

In the dashboard you choose each room's safe temperature range and who gets alerted on each channel.

03

Relax — Kelvo watches

Readings run 24/7 in the cloud. If the temperature drifts or the sensor drops, the alert goes out instantly.

Alerts you won't miss

We reach you where you'll actually see it

An email is easy to ignore at 3 a.m. That's why Kelvo speaks over several channels at once — including a phone call when it's serious.
