Monnit alternatives for cold storage monitoring, and what is worth using
By Vimal Bhaya, Founder and Lead Systems Architect · Last reviewed 31 October 2026
This is a continuation of Temperature monitoring alternatives, a 12-part tutorial. You are on part 4 of 12.
The short answer: people leave Monnit for cold storage because its texts cost extra and it cannot phone anyone on its own. Monnit is a broad wireless platform with more than 30 sensor types. Its free plan also checks in only every 2 hours, and its alerts fire on every defrost.
If you want texts and calls included and a warning before a unit fails, go for TemperatureWise, which we make. If you want Monnit's breadth with calls in the plan, Swift Sensors. A fully managed chain, SmartSense. The cheapest single box, Temp Stick.
This is a disclosed guide, not an independent ranking. Each option below gets the case where it is the better buy.
Switching out of Monnit? We make it easy as A, B, C
TemperatureWise moves you over in about a week, with both systems running side by side. On Monnit, texts come from credit packs and phone calls need a third-party link. TemperatureWise includes texts and phone calls in $250 per sensor per year, with a reading every 5 or 15 minutes and an early warning when a unit starts to fail.
- We hold a quick meeting with you to export all your data. On a short call we export your full Monnit history together, before the old account closes. TemperatureWise imports all of it free, so the old readings sit in the same record as the new ones.
- Ask whether your sensors can stay. TemperatureWise can often connect to monitoring hardware already on site, so check before buying new sensors.
- Fit TemperatureWise beside the old system. A mid-sized restaurant takes 30 to 60 minutes, with no electrician and nothing drilled: see how long installation takes.
- Run both for a week. TemperatureWise learns each box's normal pattern in its first week, and you can compare the two side by side.
- Move the alert contacts, then cancel Monnit at the end of its term. If Monnit also watches water or CO2 for you, those sensors can stay where they are. TemperatureWise has its own door contacts.
We read your old data for faults, free. Send the Monnit history and TemperatureWise looks for equipment that is failing now, and for repairs that happened in the past. If you know what a technician actually found, you can check our reading against it.
People leave Monnit because its texts cost extra and it cannot phone anyone on its own
Monnit's breadth is real, and breweries and plants use it for good reason. For cold storage, the weak point is the alert itself.
- Texts cost extra, and there is no built-in phone call. Email alerts are included. Texts come from prepaid credit packs, about $120 for 1,000 from a reseller, so someone has to keep the pack topped up, and every person added to the list burns it faster. Phone calls need a third-party service bolted on. The result is fewer people on the alert list, and no ringing phone at 3am.
- The free plan checks in every 2 hours. A walk-in defrosts about every 6 hours, so 2-hour readings cannot show the shape of the curve, and a fast failure can run for most of 2 hours before anyone knows. The Premiere plan brings it to 10 minutes, for a yearly fee.
- Alerts fire on every defrost. Monnit alerts when a reading crosses a limit, so every defrost spike or long door opening sends the same alert. Staff learn to ignore them, and then they ignore the real one too.
- It is built for everything. More than 30 sensor types is the strength. For a cold store that only watches temperature, it is a lot of platform to set up and keep running.
The breadth is why people chose it in the first place:
"We use Monnit for brite tank, glycol, zone temps, water usage, CO2."
Brewery operator, r/TheBrewery
We make TemperatureWise, and picked each alternative for a reason people leave Monnit
Renergy makes TemperatureWise, one of the alternatives on this page, so this is a disclosed guide and not an independent ranking. No vendor paid to be listed. Every alternative had to pass four tests:
- It is sold for commercial cold rooms in the US: restaurants, kitchens, cold stores or plants.
- Operators name it. It comes up in our own research into public threads where owners and technicians talk about monitoring, or it ranks where they search.
- It fixes at least one reason above. The table says which.
- Its facts can be checked. Prices come from the vendor's own pages or a named reseller, checked in September 2026, or the page says there is no posted price. Each product links to our full comparison, where every figure is sourced.
Where TemperatureWise is the wrong pick, the last section says so.
4 Monnit alternatives, each the better buy for a different site
Each alternative below fixes at least one reason people leave Monnit. TemperatureWise is ours, so it is marked, and it comes first.
| If you want | Go for | Built for | The cons |
|---|---|---|---|
| Calls included, early warning | TemperatureWise (ours) | Commercial cold rooms, one site or fifty | Temperature, humidity and doors only |
| Monnit's breadth, calls included | Swift Sensors | Sites tracking many kinds of sensor | Alerts only once the box is already warm |
| A fully managed chain | SmartSense by Digi | Chains of 50 sites or more | Expensive: an enterprise price, reported at thousands a year |
| The cheapest single box | Temp Stick | One box or a home freezer, on your Wi-Fi | No phone call, and its Wi-Fi range drops out through walk-in walls |
TemperatureWise is ours, and the pick when cold storage is the job
TemperatureWise watches cold rooms and nothing else. $250 per sensor per year includes texts and phone calls to up to 3 people per sensor, and email to as many as you name, with no credit packs. Hardware is Bluetooth (BLE) at $25 a sensor plus a $100 hub, or LoRa at $200 a sensor plus a $250 to $450 gateway.
The Bluetooth sensor reads every minute and logs every 5; the LoRa sensor logs every 15. TemperatureWise knows what a defrost looks like, so it does not wake you for one, and it warns of a failing unit at least 4 to 5 days before it fails. We put the two side by side in TemperatureWise vs Monnit.
Swift Sensors is the closest like-for-like swap
Swift Sensors covers more than 30 sensor types on one cloud screen, at about $150 for a temperature and humidity sensor and about $375 for a gateway, with the plan priced by sensor count. Text, email and phone alerts are in the plan. Some sensors run 6 to 8 years on one set of cells.
It fires on thresholds too. One plant manager said it "wasn't offering enough" for predictive maintenance, while a brewer reported years of use with no complaints. We put the two side by side in TemperatureWise vs Swift Sensors.
SmartSense by Digi takes the platform off your hands
SmartSense by Digi prices everything into one fee per asset: hardware, software, cellular data, NIST recalibration and replacement gear, with a named customer success manager. Since January 2026 it also includes Jolt's operations tools, as SmartSense ONE.
That is an enterprise price: one owner in a public thread called it "thousands per year", and it is not posted. We put the two side by side in TemperatureWise vs SmartSense.
Temp Stick is enough for one box on your own Wi-Fi
Temp Stick is a Wi-Fi temperature and humidity logger at about $149, with no subscription. Alerts by text, email and app, and the history, are included for the life of the device, and it stores up to a month of readings if Wi-Fi drops.
It runs on 2.4 GHz Wi-Fi through your router, and we found no phone-call alert on its spec sheets. The PRO model, about $199, puts the unit outside and a probe through the wall. We put the two side by side in TemperatureWise vs Temp Stick.
Before you cancel Monnit, check four things
Monnit may be watching more than your cold rooms. Sort that out before the plan ends.
- Note the plan's end date. Cancel Premiere at the end of its term, after the week of running both.
- Export the history. Premiere keeps a year of data. Download the readings and alert logs before the plan ends, and keep them as long as your rules ask: see how long to keep temperature logs. We do the export with you on the switching call.
- Decide which sensors stay. Water, CO2, vibration or power sensors can stay on Monnit. TemperatureWise covers temperature, humidity and doors, and EcoWise covers water and power.
- Stop buying text credits. Once TemperatureWise carries the cold room alerts, the credit packs are no longer needed for them.
TemperatureWise is not the right Monnit alternative for every site
Monnit covers more sensor types than TemperatureWise. If one screen for door, water, CO2, vibration, power and temperature is the goal, Monnit or Swift Sensors fits better.
Monnit can run on your own server. iMonnit Enterprise is an on-site option. TemperatureWise is a cloud platform with an API.
