NODE® delivers continuous temperature and humidity monitoring for the environments where food safety and product quality depend on stable conditions. From walk-in refrigerators and freezers to fermentation rooms, proofing cabinets, and other controlled food storage environments, NODE tracks conditions around the clock and sends data directly to ThermoWorks Cloud. Operators can check readings anytime through the ThermoWorks App and receive instant alerts if conditions drift outside safe limits—allowing teams to respond before small changes become costly losses.

Connect directly to existing Wi-Fi networks—no gateways or additional hardware required—and continuously log temperature and humidity data for review, trend analysis, and food safety documentation. NODE is available in four configurations: ambient temperature only, ambient temperature with humidity, or models with one or two external Pro-Series® probe ports for monitoring inside walk-ins, freezers, and other enclosed environments. Each unit includes a NIST-traceable calibration certificate, verifying accuracy for HACCP compliance and health inspector audits.
  • Monitor Critical Storage Conditions Remotely: View real-time temperature and humidity data from anywhere using the ThermoWorks App or Cloud dashboard.
  • Receive Instant Alerts When Conditions Change: Set custom high and low thresholds and receive immediate notifications via email, SMS, or push alerts when readings move outside your safe range.
  • Continuous Data Logging for Compliance: Automatically record temperature history with access to Min/Max values, averages, and trend graphs to support food safety documentation.
  • Connect Directly to Your Wi-Fi Network: NODE connects to existing Wi-Fi infrastructure—no gateways, bridges, or additional equipment required.
  • Monitor Refrigeration and Storage Spaces: External Pro-Series probe models allow accurate readings (±0.9°F and humidity to ±2% RH) inside walk-ins, reach-ins, proofing cabinets, and other enclosed environments.
  • Scale Monitoring Across Multiple Locations: Cloud Pro accounts support multiple users, locations, and monitoring points for centralized operational oversight.
  • Built for Commercial Environments: IP66-rated housing protects the device from dust, humidity, and splashes in kitchens, breweries, and processing facilities.
  • Verified Measurement Accuracy: Each NODE ships with a NIST-traceable calibration certificate to support inspections, HACCP verification, and audit readiness.

Reviews

We bought 6 of these

"We bought 6 of these to track the temperatures in the cold storage for our confection items. In the first few weeks they saved us from serious loss more than once: from a door left open to an unannounced power outage. They already paid for themselves 10x over. They are very easy to set up and the WiFI connection works flawlessly. In one location I paired them with a cellular modem without any issues. And yes, thanks to their batteries, the power outage was no issue. I still knew what the temperatures were. Overall we are very happy we bought these. (only issues I found were that when I tested 2 units side-by-side, they were off by a degree, and one of our suction cups is faulty and keeps falling off no matter what surface I try it on)"

The best

"We have 10 of these, and with the cloud app, they have paid for themselves in preventable food loss. We can see trends in cooling and call in a service tech to look at our refrigerators before there is a failure."

— No L. (5/5)

I have a couple of

"I have a couple of thermowork products already. They all work great and are fast for temperature taking. My latest purchase is for a Christmas present. I have not used yet I’m sure this will be another great addition ."

— Steven M. (5/5)

This has been a game

"This has been a game changer for tracking or vaccine temperatures and has saved us a lot of money with a power outage we were able to detect. I would 100% recommend this product for any place needing to keep vaccines and medicines (or any temperature sensitive things) safe."

— No L. (5/5)

Overall I think the product

"Overall I think the product is great and super handy for me to check temps when I'm not in the restaurant. I wish there was a setting so that Sessions were automatically set everyday to get a better look at the graph and can clearly see data from any day. This would allow us to have a clearer view of when temps spike and drop and catch potential maintenance issues before they happen."

Nice Product - Sends Alarms - Good App

"I like this temperature node. It was easy to setup. The app is easy and works nice. It sends alarm to my phone. I’m happy with it and would buy it again."

— Kyle D. (5/5)

We bought one for our

"We bought one for our walking cooler & freezer. A complete life changer not having to drive to our business every day checking the temps. I wish we would have purchased sooner"

— Jennifer H. (5/5)

Another Node In Play

"Just bought my third unit. Two temp/humidity and one two-port unit. All three are in-play all year monitoring different situations, acting as part of multiple monitoring devices per situation."

— Greg W. (5/5)

Works perfectly

"Works as advertised, all with the Thermoworks quality you come to expect. I love how all the Thermoworks Wi-Fi devices show up in the app. It was ver easy to set up and now I can monitor ambient temp outside my freezer and internal freezer temp via the probe, and get alerts!!"

— Shawn J. (5/5)

NODE WiFi single probe

"My NODE Wi-Fi Temperature Monitor has one probe with an ambient sensor. I use it for a freezer which keep the temperature at 0 degrees F. I wanted a low temperature alarm of -10 F, but the keyboard that popped up to enter this value wouldn't let me enter the "-" sign. I was able to do a copy/paste from another text editing app to accomplish this, tho. Other than that, this monitor has been working flawlessly."

Q&A

Can the node be put into a chest freezer on its own or does it need a probe?
NODE is safe for use down to temperatures of -13° F. However, placing a NODE inside the freezer will reduce the efficiency of the batteries and may interfere with Wi-Fi connectivity. For best results, we would recommend installing NODE on the outside of the freezer and running the included probe into the freezer.
Is there a monthly charge for the app or the subscription
There are both free and paid tiers of ThermoWorks Cloud available depending on your needs. The free tier will allow up to 10 devices.
I have a well house, would this work that? I would like to know the temperature inside, especially during the winter. If so, would I need the one with the probe so the probe would be inside and the Node on the outside. If so the Node would be out continuously in the outdoor elements. If I just put the Node in the Well house, I was wondering if it will still be able to connect to WIFI?
NODE would be an excellent solution for this as long as the temperatures in your well house are within the operating range (-13 to 122 °F). If your smartphone can connect to WiFi inside the well house, NODE should be able to connect as well.
Will this work to measure high temperature in the attic?
Yes, NODE can be used in the attic. The NODE is rated to 122°F. If it is getting hotter than 122°F, we do not recommend leaving NODE in your attic.
Do the models with probe ports come with probes or do you have to buy them separately?
Yes, any NODE model with probe ports ships with the corresponding number of probes.
