Cloud-based Worldwide Access
Track temps, humidity, 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 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.
Pro-Series Probes
Choose from ambient temp only, ambient temp/humidity, or ambient temp + 1 or + 2 external Pro-Series probes. External probe models work 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 and humidity is important, put a NODE there!
Access your critical temps and humidity anytime, anywhere with the ThermoWorks app on your phone. Check Max/Min temps and humidity, Avg. temp/humidity, and temperature/humidity 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 dashboard in the cloud and browse your history, zoom in and out of your multi-channel 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 tracking more than 10 connected thermometers at once, assigning levels of access to other team members, and receiving SMS text and email trigger alerts. Learn More

Download NODE Operating InstructionsNODE FAQ
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. Specialty NODE kits are available with buffered probes to simulate food items in cold environments where opening and closing doors can affect the accuracy of ambient readings.
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. For example, if your transmission interval is set to 1 hour, NODE will store 100 readings over 100 hours or just over 4 days.
Q: Will I get notifications in the event of a power failure?
A: Yes, in any paid Cloud tier you can enable Offline Alerts so even if power is out in your location, you’ll get alerts to your devices from the Cloud that transmissions have been missed.
Q: How are notifications managed with NODE?
A: Notifications can be set up in the app or cloud. In the free cloud tier push notifications are sent to your smart device(s) as an app notification (the app needs to be installed on the device, but 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 a way to integrate with NODE?
A: You can integrate NODE into your own existing IoT infrastructure. Contact commercial sales for more information.
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/Cloud will make you aware of these times. Battery life is affected by transmission interval, frequency of alerts, Wi-Fi signal strength, and use in colder ambient temperatures. Use lithium high energy batteries to extend battery life. . 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. This allows you to save battery life by extending the transmission interval, knowing that NODE checks for alarm conditions during each Temp Check interval with minimal battery drain.
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: What are the transmission interval limits for NODE?
A: By default, NODE is set to transmit every 30 minutes, which is independent from the Temp Check Interval. In the App, the transmission interval can be set from 30 minutes to 24 hours, and in the Cloud the transmission interval has more options, from 1 minute to 24 hours. Readings are sent to the Cloud on the transmission interval – one reading per channel at each interval.
Q: How often does NODE update the readings on each channel?
A: The temperature reading(s) on the NODE display 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 only. 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.
Q: Is NODE’s Wi-Fi signal strong enough to make it out of my large walk-in fridge?
A: In most cases, yes, however signal strength is dependent on many variables including wall thickness of your walk-in, your router’s coverage area, and other interference within the building. In some cases, it may be best to use a NODE with an external probe and leave NODE outside of the walk-in while the probe is kept inside.
Q: What is the accuracy of NODE?
A: NODE has a system accuracy (meter and probe) of ±0.9°F (±0.5°C) over its full range with the supplied probes in the correct probe ports. NODE uses Pro-Series probes and can be interchanged; however, system accuracy will be ±0.9°F (±0.5°C) from 32 to 77°F (0 to 25°C), ±1.8°F (±1.0°C) full range.
Q: How do I recalibrate NODE?
A: For highest accuracy, NODE systems should be system calibrated at ThermoWorks A2LA accredited calibration laboratory. We recommend a recalibration interval of 1 year.
