The 4 a.m. problem
Nothing in your kitchen tells you it is failing.
The compressor gives out sometime after close. The walk-in creeps to 50 °F. Nobody opens that door again for nine hours. By the time the morning crew walks in, the dairy is gone, the protein is a judgment call you should not have to make, and you are already three hours into a service call you did not budget for.
The difference between a $40 door gasket and a $10,000 morning is knowing at 9:36 PM.
- 9:36 PMDrift begins
Cooler climbs past 41 °F. Nobody is in the building. A paper log would not catch this for another eleven hours.
- 9:36 PMSensitii texts you
SMS and email to you, your GM, and your kitchen manager — with the reading, the unit, and how long it has been out of range.
- 10:05 PMSomeone acts
Door left ajar, fan iced, breaker tripped — most overnight events are fixable in minutes if a human knows about them.
- Next morningThe log is already written
The event, the response, and the corrective action are in your HACCP record before the inspector ever asks.
Why it matters
The money is already leaving. You just cannot see it.
Refrigeration failure is not the only cost of not knowing — it is only the loudest one. Here is the shape of the problem operators keep telling us about.
4 hours
The clock that empties your walk-in
Under FDA Food Code guidance, potentially hazardous food held above 41 °F for more than four hours must be discarded. No exceptions, no smell test. An overnight failure nobody sees does not cost you a compressor — it costs you the entire box.
Source — Walk-In Cooler Failure Costs in Dallas — Honest Local Service
$8k–$15k
What one overnight walk-in failure costs
Lost inventory, an emergency refrigeration call at holiday rates, and the covers you cannot serve while you rebuild par. A single event, on a night when nobody was in the building.
Estimate — inventory, emergency service, and lost service combined
After hours
When compressors actually fail
Refrigeration does not choose business hours. The failures that hurt happen overnight, on weekends, and over holidays — precisely when no one is walking past the thermometer.
Estimate — widely reported pattern in commercial refrigeration service
41 °F vs 38 °F
Three degrees halves your shelf life
A cooler running a few degrees warm does not trip an alarm and does not look broken. It quietly shortens the life of your highest-margin protein and dairy, and you write it off as ordinary waste.
Estimate — food safety shelf-life guidance
One system, three parts
We build the sensors, the network, and the software.
Most monitoring vendors resell someone else's hardware and bolt a dashboard on top. Sensitii owns the whole path — from the probe inside your walk-in to the text message on your phone — so when something needs fixing there is exactly one number to call.
LoRaWAN temperature sensors
Sensitii Tags
Battery-powered wireless probes for walk-ins, reach-ins, freezers, prep tables, hot holding, and dry storage. Non-invasive mounts — no drilling, no wiring, no holes in your box.
- 10-year battery life
- Reads every few minutes, day and night
- Survives −40 °F freezers and 185 °F wash-down heat
LoRaWAN gateway
Sensitii Core
One gateway covers an entire restaurant — through walk-in walls, coolers, and concrete that kill Wi-Fi and Bluetooth. Backhauls over Ethernet, Wi-Fi, or LTE, so a downed ISP is not a downed monitor.
- Long-range sub-GHz radio, built for metal boxes
- Ethernet · Wi-Fi · LTE failover
- Buffers readings through internet outages
The monitoring & compliance platform
Sensitii
Live dashboard, threshold alerting by SMS and email, auto-generated HACCP temperature logs, corrective actions, and audit-ready history — for you and every user you add.
- Unlimited users on every plan
- SMS + email alerting per person, per location
- Exportable logs for the health inspector
Alerting
Everyone who needs to know. On the channel they actually read.
Alerts are not a single phone number buried in a settings page. Every user on your account gets their own routing — SMS, email, or both — scoped to the locations they are responsible for.
SMS and email, per user
Add your GM, your kitchen manager, your refrigeration tech, your partner. Each one picks their channels. Unlimited users on every plan — we never charge per seat.
Escalation, not spam
One alert per event, held open until the unit recovers. A cooler that bounces in and out of range does not send forty texts.
Early warning before breach
Units approaching a threshold are flagged as watch before they cross it — so you get a heads-up, not just an autopsy.
Recovery confirmation
When the box comes back into range, everyone who got the alert gets the all-clear with the duration of the excursion.

HACCP & audits
The clipboard never sees another shift.
Temperature logs stop being something a line cook fills in from memory at the end of the night. They become a continuous, timestamped record that nobody has to remember.

Getting started
Installed for you. Not shipped to you in a box.
We do not mail you a kit and a PDF. A Sensitii install is an appointment in Dallas–Fort Worth: we place every sensor, confirm every unit is reporting, and set your thresholds with you before we leave.
- 01
We walk your kitchen
Free, on-site. We look at every unit that holds product — walk-ins, reach-ins, freezers, line rails, hot holds, dry store — and tell you which ones are worth monitoring and which are not.
- 02
We install, in under an hour
Tags go in, Core goes up, every unit is confirmed reporting live before we leave. Nothing is drilled and nothing is wired into your refrigeration.
- 03
We set your thresholds with you
Your ranges, your units, your escalation list. We add your GM, your kitchen manager, and anyone else who should get the text — with their own SMS and email preferences.
- 04
It runs, and we watch it with you
Device health, battery level, and gateway connectivity are monitored on our side. If a Tag stops reporting or a battery is nearing end of life, we contact you.
The full picture
Four ways a kitchen loses money to temperature.
Spoilage is the obvious one. The other three are quieter and, added up over a year, usually larger.
Spoilage you already absorb
The loss that never shows up as an incident, because it looks like normal waste.
$1,000–$1,500
Avoidable perishable spoilage, per month
Not the dramatic failures — the ordinary drift. A typical independent restaurant absorbs four figures a month in perishables that spoiled early because a box ran warm and nobody knew.
Estimate — Typical independent restaurant, industry figures
Up to 1/3
Of food waste happens before it reaches a plate
Back-of-house loss in cold storage is the largest single slice of restaurant food waste, and temperature is the biggest lever on it.
Estimate — back-of-house share of restaurant food waste
20×
The revenue it takes to cover what you throw away
At a 5% net margin, every $50 of spoiled protein you bin needs $1,000 in new sales just to get back to even. Waste is not a cost line — it is a sales target.
Estimate — Arithmetic at a 5% net margin
Labor spent on a clipboard
What manual temperature logging costs, and what it fails to catch anyway.
120+ hrs
Per location, per year, holding a clipboard
Ten minutes twice a day, every day, at manager wages. That is thousands of dollars annually to produce a record that is less complete than one an automated sensor writes for free.
Estimate — Arithmetic — 10 min × 2 checks × 365 days
Backfilled
Paper logs get filled in at the end of the shift
Everyone in this industry knows it. A log completed from memory at 10 PM is not a food safety control and it will not hold up when an insurer asks you to prove the box was cold.
Estimate — Widely reported industry practice
Everything
That a twice-daily check misses
Two readings a day means twenty-two hours of unmonitored time. Every spike between checks — a propped door through a delivery, a defrost cycle that hung — is invisible.
Estimate — Arithmetic — coverage of two point-in-time checks per day
Equipment bleeding money quietly
Continuous data turns refrigeration from a surprise into a maintenance schedule.
Every 1 °F
Colder than necessary shows up on your utility bill
Uncalibrated thermostats routinely run boxes colder than they need to be. You pay for that every month, and there is nothing on the wall that tells you it is happening.
Estimate — commercial refrigeration energy guidance
Rising duty cycle
Is what a failing unit looks like weeks early
Dirty coils, worn gaskets, and icing make a compressor work harder long before it dies. Continuous temperature history makes that trend visible while it is still a maintenance call.
Estimate — refrigeration preventive maintenance practice
$250–$400/hr
Emergency refrigeration service, plus the trip charge
That is the rate you pay at 2 AM on a Sunday because nobody saw it coming. Scheduled maintenance on a trend you spotted costs a fraction of it.
Estimate — after-hours commercial HVAC/R service rates
Records you can actually produce
The difference between a claim that pays and a claim that stalls.
Prove it
Spoilage claims turn on verifiable temperature history
An insurer settling a spoilage claim wants continuous evidence that the equipment failed and when. A handwritten sheet with gaps is not that evidence. A timestamped record from an independent sensor is.
Estimate — common spoilage claim documentation requirements
Audit-ready
Logs that are complete, legible, and already written
Incomplete or unreadable temperature logs are a routine inspection finding. Sensitii's are generated continuously and exported as a clean date range in a few clicks.
Estimate — Common health inspection finding
Linked
Corrective actions attached to the event that caused them
Not a separate binder. The excursion, who was notified, what was done, and who signed off live on one record.
Estimate — Sensitii platform capability
On these numbersFigures marked as estimates are industry rules of thumb and cost ranges, not measured results from Sensitii customers. We publish them because they are the numbers operators use to size the problem — not as a promise of savings. Your kitchen is its own case study, and we will help you build it.
Security
Built so a compliance record is worth something.
A temperature log only helps you if nobody can quietly change it and nobody outside your business can read it. Sensitii is architected around that from the database up.
Your data is isolated in the database, not in app code
Every row belongs to your tenant, and Postgres row-level security enforces it on every read and write. A bug in a web page cannot reach another restaurant's data, because the database itself refuses.
Role-based access you control
Owners, managers, and staff see what you decide they see. Define your own job titles and permissions, per location.
Devices are authenticated and rotatable
Every sensor and gateway has its own key, stored hashed, and rotatable without a site visit.
Privileged actions are logged
Threshold changes, user invitations, and sign-offs write to an audit trail you can read.
Pricing

Questions we get on the first call.
Anything not covered here, ask us directly on the demo — we would rather tell you Sensitii is a poor fit than sell you a system you will resent.
Under an hour for a typical single-location restaurant. We come to you, place the Sensitii Tags, mount the Sensitii Core gateway, verify every unit is reporting, and set your thresholds with you before we leave. Nothing is drilled and nothing is wired into your refrigeration.
Sensitii Core buffers readings locally and backfills them when the connection returns, so your HACCP record has no gaps. Core can also backhaul over LTE, so a downed ISP does not blind your monitoring.
No. Sensitii Tags talk to the gateway over LoRaWAN — a long-range, sub-GHz radio that passes through walk-in walls and metal that stop Wi-Fi and Bluetooth. Only the Core gateway touches your network.
Sensitii Tags are rated for a 10-year battery life. We monitor battery level as part of device health and reach out to you when a Tag needs service — you never have to track it.
As many as you want. Unlimited users are included on every plan, each with their own SMS and email preferences and their own location access. We do not charge per seat.
Temperature is what we install today. If you need a different range or a different measurement, ask — we build the hardware, so integrating a different probe is a conversation, not a product roadmap request.
Yes, and it is enforced in the database rather than in application code. Every row is scoped to your tenant by Postgres row-level security, so cross-tenant access is not something a bug in a web page can cause.
We install and support across Dallas–Fort Worth today. If you are outside that footprint, get in touch — we will tell you honestly whether we can support you well yet.
