TemperatureWise for convenience stores

Temperature monitoring for convenience stores

In a convenience store every cooler is its own machine, so a fault stays in one cabinet. TemperatureWise gives each cabinet its own record, from $25 a sensor, so you can show which cooler failed and when.

  • Independent stores
  • Franchise groups
  • Refrigeration service partners

What you get

Four things TemperatureWise does for a convenience store

Every store and every cabinet, on one screen

Each store gets its own hub. Every cooler in every store shows on one screen, and each alert names the store and the cabinet.

A record the bottler cannot argue with

When a bottler's cooler fails, its own readings show when it started and how warm it got. That is what gets a technician booked.

Alerts reach the store and the contractor

Email, then a text, then a call, to up to three people per sensor: say the store manager, the district manager and the refrigeration contractor.

It fits any cabinet, including the bottler's

The sensor sits inside the cabinet on a magnet or an adhesive pad. Nothing is wired into the cooler, and TemperatureWise never touches its controller or its energy settings.

Where it goes wrong

Three failures worth an alert, and the daily ups and downs that aren't

Every cooler in a convenience store is its own machine, so a failure stays in one cabinet. The job is to spot the one that is failing among the ones that are just busy.

A row of five glass-door coolers, each with a TemperatureWise sensor. The middle one, owned by the drinks bottler, has warmed while the four beside it hold. Its own readings, showing when it started and how warm it got, go to the bottler's service line.
How it fails

A bottler's cooler fails, and the fix waits on the bottler

Many glass-door coolers belong to the drinks bottler, not the store. When one fails, the store cannot send its own contractor, and the bottler's service is slow. A record from that one cabinet, showing when it started and how warm it got, is what gets a technician sent.

One cabinet warm, the rest of the store fine
How to tell
Its neighbours hold
A glass-door cooler seen from the side, pushed against a wall. Its condenser at the base blows hot air into the gap, the air hits the wall and comes straight back into the condenser, so the cooler breathes its own heat. Dust on the coil makes it worse. It runs longer on warm, busy days, then slips week by week.
How it fails

A cooler pushed against the wall breathes its own hot air

A glass-door cooler sheds its heat into the store through a condenser at the base or the top. Pushed against a wall, or clogged with dust, it breathes its own hot air. It runs longer on warm, busy days, then slips week by week.

The glass-door front of a walk-in beer cave with six doors. One door's closer has broken, so the door hangs open between customers and warm store air keeps coming in. Normally each opening is a short spike that clears; with the door hanging open, the spikes run together into a warm stretch.
How it fails

A broken closer leaves the beer cave door open

The beer cave, a walk-in with glass doors, gets opened all day. Each opening is a short spike that clears. When a door closer breaks, the door hangs open between customers, and the spikes run together into a warm stretch.

A threshold alarm goes off for these every day. TemperatureWise learns them in its first week.

Store rushes, energy-saving schedules, restocking and defrosts move the temperature every day. None of them is a failure.

A threshold alarm

Sounds whenever a cabinet crosses one fixed line. A busy hour, a schedule or a defrost crosses it, so it goes off every day and staff learn to ignore it. In one real freezer log, a normal defrost set it off for 55 minutes. More in why temperature alarms cry wolf.

TemperatureWise

Learns each cabinet's normal pattern in its first week: its busy hours, its energy-saving schedule, its restocking and its defrosts. It stays quiet for the routine and alerts when a cabinet stops behaving like itself, like the three failures above. No false alarms from a normal day.

A convenience store day from midnight to midnight with three busy periods: morning, lunch and after work. Cooler and beer cave doors open again and again in each busy period, and the cabinets run warmer, then recover. That is normal, and TemperatureWise learns it. Example day.
The rush Doors open again and again at the store's busy hours. The cabinets run warmer, then recover.

Energy saving Many drinks coolers raise their setpoint and switch off their lights on a schedule. It looks like a fault. It is the design.
The back of a walk-in beer cave. Cases that have been sitting in the back room go in behind the glass doors on a hand truck, and the cave warms for a while as it pulls the new stock down. That is normal, and TemperatureWise learns it.
Restocking Cases from the back room go in behind the glass, and the cave warms for a while.

Defrosts A defrost warms the air for a short time, several times a day. The stock stays cold.

From the field

Small refrigeration breaks most often, and a convenience store loses the stock

A service manager at a publicly traded trades firm, a Renergy partner, looks after about 1,200 commercial sites. We asked him where the calls come from.

A bar chart of what a repair costs against planned maintenance, in dollars of labour and parts, as a service manager at a Renergy partner gave it. For every $1 of maintenance, a repair on small refrigeration costs about $8, and a repair on a commercial rooftop unit about $4.

What he told us

  1. Small refrigeration: reach-ins and walk-ins. "Small refrigeration break[s] more often."
  2. A convenience store, ahead of a hospital. "Hospitals have contingency. Convenience stores lose product."
  3. About 8 times the maintenance, in dollars of labour and parts, on small refrigeration. About 4 times on rooftop units.
  4. About 30 to 40% of his commercial clients have some monitoring. A fuel and convenience chain with about 2,000 sites in Canada was having temperature sensors fitted in its coolers and cold rooms when we spoke.

TemperatureWise is built for that small refrigeration: the coolers, the beer cave and the cases.

His point about price matters too: some owners will spend $50 a unit and some $2,000, "but they all want the same result at the end." TemperatureWise hardware starts at $25 a sensor, near the low end of that range, and the monitoring is $250 a sensor per year on top.

Pricing and payback

One store costs $250 up front and $2,000 a year

One store: a beer cave and six other cabinets

ItemOncePer year
8 entry sensors at $25$200
Hub$50
Monitoring, 8 sensors at $250$2,000
Total$250$2,000

Two sensors in the beer cave, and one in each of four glass-door coolers, the grab-and-go case and the ice freezer, on the store's own internet. A long store may need a second $50 hub. Cellular is $125 once and $50 a year where the store network is off limits. The price list notes further discounts depend on the deployment. Price list of 1 September 2026.

A repair costs about 8 times the maintenance

On small refrigeration, a repair costs about 8 times what planned maintenance does, in dollars, according to the service manager above. Catching a cooler while it fades turns the repair into planned work.

TemperatureWise monitoring is $250 per sensor per year, about $21 a sensor a month. The record from each cabinet is also what gets a bottler's cooler fixed, which the store cannot do by itself.

How it works

Three steps, no tools, the store stays open

  1. We plan it from your store layout

    TemperatureWise marks where each sensor and the hub go before anything ships.

  2. You place a sensor in each cabinet

    A magnet or an adhesive pad, no tools. The hub goes into an ordinary socket near the coolers.

  3. It learns each cabinet in the first week

    Its busy hours, its energy-saving schedule and its defrosts, so none of them is an alarm.

The rules

The temperatures a convenience store is held to

US · FDA Food Code

Cold food is held at 41°F (5°C) or colder, in a grab-and-go case as much as in the walk-in.

Read the FDA Food Code

Ontario · O. Reg. 493/17

Food is held at 4°C (39°F) or colder (s. 27), frozen food stays frozen (s. 28), and every unit has an accurate thermometer (s. 30).

Read O. Reg. 493/17

The rule follows the food, so milk and sandwiches in a bottler's cooler count too. TemperatureWise produces the record for every cabinet; the sign-off stays with you.

Common questions

How much does convenience store temperature monitoring cost?

$250 up front and $2,000 a year for a store with a beer cave and six other cabinets on TemperatureWise entry sensors. Each extra cabinet adds a $25 sensor and $250 a year, and the price list notes further discounts depend on the deployment.

Can TemperatureWise monitor a cooler the bottler owns?

Yes. The TemperatureWise sensor sits inside any cabinet on a magnet or an adhesive pad, without touching its controller. Its record is what you send the bottler when that cooler fails.

Will a drinks cooler's energy-saving setting set off alarms?

Not with TemperatureWise. It learns each cabinet's schedule in the first week, so a setpoint raised on the hour is not an alarm. A simple threshold alarm often does go off, which is why staff learn to ignore it.

Can TemperatureWise tell when the grab-and-go case is overfilled?

No. Food stacked above the load line sits in store air and warms while the case itself reads normal. No sensor in the case sees that; keeping stock below the line does.

Does TemperatureWise work for a convenience chain?

Yes. Each store gets its own hub, every store shows on one screen, and each alert names the store and the cabinet. TemperatureWise does not monitor the car wash or the store's own heating and cooling.
