Cloud-based Worldwide Access
Track temps, Max & Min, averages, alarms and more from the ThermoWorks App on your phone or your cloud dashboard.
Easy Set Up
The app walks you through a few easy steps to connect your NODE to your Wi-Fi network right out of the box.
Instant Trigger Alerts
Set High and Low alarms for each channel and get notified on your phone as soon as something’s wrong.
Rugged and Waterproof
Ready for commercial use with reinforced housing and IP66 splash-proof rating. Battery lasts about a year depending on settings.
Choose from ambient only or + 1 or + 2 external Pro-Series probes. Works with all Pro-Series Probes for many applications.
NODE is an exciting new entry in the Internet of Things (IOT) allowing you to monitor the temperature of anything that you care about from anywhere and receive alerts when the temperature gets too hot or too cold.
Each NODE comes with its own color-matched clip that easily mounts to the wall with powerful magnets or by screwing it in place. The included Pro-Series Probes have suction cups so they stay where you put them. Anywhere monitoring temperature is important, put a NODE there!
Access your critical temps anytime, anywhere with the ThermoWorks app on your phone. Check Max/Min temps, Avg. temps, and temperature graphs. Set session parameters and change your high and low alarms on the fly. Schedule notifications and configure your account right from the app, including customizing the names of each NODE and each channel.
Or log into a centralized temperature dashboard in the cloud and browse your history, zoom in and out of your multi-channel temperature graphs, annotate alarm events, and customize your settings. ThermoWorks cloud is fully secure and adds capacity automatically as needed so you never suffer downtime at the wrong time.
Subscribe to a Pro or Business Pro Cloud account for more features like increasing the frequency of transmissions, tracking more than 5 connected thermometers at once, assigning levels of access to other team members, and receiving SMS text and email trigger alerts. Learn More

Q: Does NODE come with probes?
A: Yes, it depends upon the model. TX-5401 is Ambient only, but waterproof Pro-Series Probes are included in both TX-5403 (1 probe included) and TX-5404 (2 probes included). And both of those models accept any Pro-Series Probes.
Q: Can NODE be permanently powered?
A: Yes. NODE has a standard 5-volt power adapter and cable included in the box. Can also be battery powered.
Q: What happens if the power goes out? Do I still get my data?
A: NODE will hold 100 readings in memory and will transmit the data when an internet connection is restored.
Q: How are notifications managed with NODE?
A: Notifications can be setup in the app or cloud. In the free cloud tier push notifications are sent to your smart device as an app notification (the app does not need to be open for notifications to be received). Upgrade to a paid tier to have SMS and email notifications sent to all team members based on their specific permissions.
Q: Does NODE have an audible alarm?
A: No. But you will receive alerts through ThermoWorks App/Cloud on your phone and/or web browser. There is an alarm bell on the display of NODE that indicates an alarm state.
Q: Why can’t I see my data in ThermoWorks App/Cloud immediately after set up?
A: NODE will transmit data on the selected Transmission Interval (default set to 30 minutes). To force a transmission, press and hold the SEND button for 3 seconds.
Q: Is there an SDK?
A: Not at this time.
Q: Are the probes that are included with NODE fully waterproof?
A: Yes, the included probes are fully submersible for use in aquariums, outdoors, and wet commercial environments.
Q: How long will NODE typically last on battery power?
A: One year is typical with a 5-minute Temp Check Interval and 1-hour Transmission Interval. Battery life may be less or more if these intervals are adjusted. The app and cloud will make you aware of these times. Remember, NODE can be permanently powered with the included AC adapter or any standard 5V adapter.
Q: What is the Temp Check Interval?
A: How often NODE wakes to check temperatures against the alarms and update the display. If an alarm state is found during the Temp Check Interval a transmission is triggered and notifications sent if they are enabled.
Q: What is the Transmission Interval?
A: How often NODE transmits temperature data to the ThermoWorks Cloud.
Q: Can I force a transmission in between the transmission intervals?
A: Yes. Press and hold the SEND button for 3 seconds to initiate a transmission. Any pending updates that are queued up for the next transmission are sent during a forced transmission.
Q: How often does NODE update the readings on each channel?
A: The temperature reading(s) is updated at each Temp Check interval and the display automatically switches to the next channel for multi-channel NODEs. Alternatively, pressing the SEND button switches the display to the next channel, updates the temperature reading, and performs a Temp Check.
Q: Can I use NODE in my country?
A: NODE has been registered and approved for use in the USA, Canada, EU, Australia, and New Zealand.
Q: What Wi-Fi restrictions are there for setting up NODE on my Wi-Fi?
A: NODE uses the 2.4GHz band. Most routers have 2.4GHz as an available band for use with specific devices. Our technical support team is available with extended hours to help with any NODE setup questions: Mon-Fri, 6:00 a.m. to 7:00 p.m.; Sat, 8:00 a.m. to 5:00 p.m.
Q: Is NODE VFC compliant?
A: Yes, NODE is compliant with the CDC’s Vaccines for Children program when using the ThermoWorks App and Cloud.
Q: Can I use NODE to monitor my restaurant’s walk-in fridge?
A: Yes. NODE would be ideal to monitor all cold holding areas. Set your alarm limits and NODE will send you a notification if the temperature exceeds your alarm conditions. Call our commercial sales team for help finding the best solution for your application.
