What does kohr.io monitor?

Temperature in walk-in freezers, display cases, and cold storage. Humidity only when that sensor is ordered. The customer warning is for product at risk — a box that is warming or has gone silent.

What is in the site kit?

One indoor hub and two sealed temperature sensors. The hub uses Ethernet or Wi-Fi. A 4G hub is available at extra cost if the shop has no usable internet. Extra sensors are $89.

How much is monitoring?

$29 per month per location for up to four sensors, then $8 per extra sensor. An extra hub at the same address is hardware, not a second monthly fee.

Does kohr.io diagnose a failed compressor?

No. The public product is a temperature log and a product-loss warning. Machine notes can be shown to a service partner after they sign off. That is not a customer text.

The product

A temperature log on every box, and a warning before the product spoils.

Name: kohr.io freezer monitor kit
Brand: kohr.io
Availability: PreOrder

kohr.io is a wireless freezer monitor for restaurants, plants, and shops that already lose sleep over a warm walk-in. A small hub in the shop hears a sealed sensor in each box. The app keeps the history. You get a message when that box starts to warm — not after the ice cream is soup.

What you are buying

One indoor hub and sealed sensors. The hub is the box that talks to the internet. The sensor is the box that sits in the freezer. Customers never need the radio name “gateway.”

Each sensor writes a temperature on a regular beat and keeps its own log if the hub is down. The app shows the last reading, a short history, and a warning when product may be at risk.

Price

Site kit — hub + two sensors$499–$549

Extra sensor$89

Monitoring, up to four sensors at one address$29 / month, then $8 each extra

A 4G hub is an extra-cost option when the shop has no usable Wi-Fi or Ethernet. Humidity, door, occupancy, and CO₂ sensors are sold when someone asks. Humidors and indoor-air kits are separate.

Who it is for

Food plants, restaurants, last-mile bags, churches and schools with kitchens, and the refrigeration shop that already has a key to the box. The pitch is a written log instead of a guess at 2 a.m.

Who it is not for

It is not a legal measuring instrument. It is not a compressor tester. It does not text the cook about a short cycle or a slow drift. Those notes, when they exist, stay with the account and the service partner.

Two kits

Temperature kit. A hub and sensors in the boxes. A cook or a manager can place those after a short walkthrough. This is the log and the warm-box warning.

Walk-in professional pack. Air sensor, door contact, and current clamps on the unit feed, the compressor, and the evap fans. That pack can flag an emerging problem while the product is still cold. It does not name the part. A refrigeration technician must install it. It is a service visit, not a carton you hang yourself.

If you want the machine flags, ask for the professional pack and book the tech. If you only want to know the ice cream is cold, order the temperature kit.

How a shop uses it

Name the street and each box on the order list.
Hang the hub. Place one sensor in each cabinet.
Sign in on the phone. Add the app to the Home Screen if you want the icon.
Turn on alerts on that phone for product-loss warnings.

Questions people ask

Does the sensor need Wi-Fi inside the freezer?

No. The sensor talks to the hub. The hub uses Ethernet, Wi-Fi, or 4G.

What units does the app show?

Fahrenheit or Celsius. There is a switch on the live page. English and Spanish pages describe the range in Fahrenheit. Other languages on the public site use Celsius.
