NODE delivers continuous temperature and humidity monitoring for the spaces that matter most — wine cellars, greenhouses, garages, freezers, vacation homes, and more. Every unit ships with a NIST-traceable calibration certificate, so the data you’re monitoring is accurate from the start. Check current conditions anytime through the ThermoWorks App, and receive instant alerts when readings drift outside your set range. Early notification means early intervention, before minor shifts become costly problems.

Four configurations let you match NODE to your monitoring needs: ambient temperature only, ambient plus humidity, or models supporting one or two external Pro-Series® probes for fridges, freezers, fermentations, soil, or hard-to-reach locations. NODE connects directly to Wi-Fi and logs data to the cloud, where you can review trends, adjust alarms, and track conditions over time. 

  • Remote Access via App or Dashboard: View current conditions from anywhere using the ThermoWorks App or cloud interface.
  • Configurable High/Low Alarms: Set custom thresholds and receive instant notifications when readings fall outside your range.
  • Historical Data and Trends: Review Max/Min values, averages, and graphs to track how conditions shift over hours, days, or weeks.
  • Four Configuration Options: Ambient-only, ambient + humidity, or models with one or two Pro-Series probe ports.
  • Pro-Series Probe Compatibility: External probe models connect to the full Pro-Series line for monitoring fridges, freezers, soil, liquids, and enclosed spaces.
  • Guided Wi-Fi Setup: Step-by-step in-app instructions connect NODE to your home network in minutes.
  • Durable, Splash-Resistant Build: IP66-rated housing and long battery life support continuous, long-term monitoring.
  • Verified Accuracy: Every unit ships with a NIST-traceable calibration certificate.

Perfect for my application

"I had a frozen water pipe under my pump cover that cost quite a bit to repair. I added a thermostat and heater to prevent freezing. Then I thought, how will I know if the thermostat or heater stop working? This was the solution. Very helpful staff and quick delivery. Made 1 hole for the probe and power supply and a plastic rain cover. I will sleep better during the cold winter months knowing I can check on my pump cover in seconds."

Another great tool!

"I have a refrigerator and a freezer in my garage that’s generally full of food and I always worry that something could go wrong and I won’t know about it for a couple of days. So I got the dual probe Node and it’s even better than expected. Like all Thermoworks products it’s so well thought out and just works exactly as you would hope. I can check the temperature of my refrigerator/freezer from anywhere and of course there’s high temp alarms to let me know if there’s a problem. I’ve been a big fan of their cooking thermometers for years and now I’m a fan of their refrigerator/freezer thermometers as well."

Deep freezer

"The only feedback is that 1) I wish I could remove the notifications for the "Low" temperature warnings. I have the suction cup, but it doesn't stick to any type of surface in the freezer - despite the surfaces being clean and free of ice. Aside from this it works great."

Q&A

Will I be able to monitor my Node when I’m traveling? It will be connected to my home WiFi.
Yes absolutely! If whatever device you're checking on (phone, tablet, laptop), has an internet connection, you'll be able to see what's going on with your NODE at home.
I have two probe model and use for refrigerator and freezer. The probe wires are a little thick and they make a small air leak on the seal for the doors. Do you have any suggestions how to minimize the air leak?
Some gaskets are more forgiving than others. Simply moving the cable a few inches down the door or to the other side of the frame can sometimes solve the problem. If your gasket is a little too firm to fully conform to the cable, you can check with the manufacturer for their recommendations.
I have a Node but I would like to purchase an external probe to attach to it. Is this possible ? Thank you.
Yes you can, depending on which NODE you have. If your unit has a probe port (1 or 2 channel), you can add a compatible external probe. If it’s an ambient-only version, then it won’t support an add-on probe.
