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 6:00 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.

Thermo Works Hydrometer
The hydrometer I purchased from Thermo Works is a true wonder of technology. It is installed in my studio under the concert grand piano, and enables me to track humidity changes on an hourly basis from wherever I happen to be; currently Catalonia, Spain. Well done, Thermo Works!

Great gadget, but needs a backlight
I really like this node device. The only thing I don't like is it has no back light so you can check temps in person.

Works great once it is connected to WiFi
The main issue I had was getting the node connected to my mesh WiFi. Once it was connected, it has worked perfectly and given me some insight on the temperature fluctuations in one of my freezers.

Only uses 2.4gH wifi
Love the fit and finish. I didn't realize it only communicates with 2.4gH WIFI. It only configures with the app over WIFI. Sooooo I'm stuck until I can buy a slow 2.4 gH modem and somehow get that to communicate with my 5gH

Great idea - poor user interface
This would be a great device except for its user interface. The button and the display are just not intuitive at all. E.g. you get an alarm on your phone that a temp is too high; then you go to the device and look and the display is not the same as the value in the alert. There should be a "Read Now" button so you can push every few seconds to see if the temp is moving in the right direction. Instead it just toggles from one channel to the next. The other thing I don't like is that the display won't stay on the channel you want to monitor - it seems to always move to the internal so you have to get up, go to the node and cycle to the channel you want to see.

Already paid for themselves!
Commercial kitchens and other organizations with walk-in refrigerators and freezers are the primary target market for the Node product line, and I know of one occasion when a Node would have saved tens of thousands of dollars worth of food from going bad. But at home, a freezer could very easily hold hundreds of dollars worth, so we have Nodes on our freezers in the garage and the fridge in the kitchen, to protect us from financial loss and inconvenience if the fridge or a freezer gets unplugged or a door gets left open, but also from possible food safety problems if the problem gets resolved before it's noticed but after the food has been in the temperature danger zone.
Sure enough, our chest freezer came unplugged, and the garage Node duly notified me in time.
As a bonus, I can look at my phone and see if I need to put on a jacket to go out and work in the garage.
I had a question about extending the probe cables, and ThermoWorks' customer support was excellent, as always. (You can buy extension cables). Devices were easy to set up.

So Far Completely Satisfied
I need to monitor the temperature in my weekend home and my previous device manufacturer (Lacrosse) no longer supported my devices. So a search revealed Thermoworks Node. The price was initially a little tough to take but the reviews were solid and I wanted good equipment. I placed an order for 3 Node units. The order shipped very promptly and was in my hands in less than 1 week via USPS. I installed the 3 devices yesterday. The setup was very easy. It could be made easier if the Node units were able to search for available wifi networks. You have to enter the SSID manually, along with the password. The app is intuitive, and very easy to use. The alerts for each sensor/ remote can be set and changed easily. Each of the channels can be labeled separately and each Node can also be labelled. Overall, Thermoworks Node devices are well made and meet my monitoring needs perfectly.

The only ThermoWorks product I can't figure out
I have called to get help setting these up and was told I need my cable provider to come set it up. It is VERY dependent on a certain narrow bandwidth. This does not appear to be a HO product.
