Frigga M2H Reusable Temperature Humidity Data Logger Multi-Use USB Digital Temperature Recorder 28800 Points High Accuracy Refrigerator Thermometer Logger PDF CSV Report

Multiple report types. Great information. inexpensive. I have used this to track issues in several buildings. Couldn't have found the problems without this data logger.

It says you don't need software on your computer to read the data on it. What they don't say is that you do need software on your computer to set it up. For MacOS, that software is available on the Apple App Store, so that should be safe, right? Sure, until that app then automatically downloads other software directly from their web site, a DMG that contains a PKG, which you are required to install for the device to be configured, which then installs a service on your computer that runs all the time. As root. Then the "Uninstall" application that they provide is a binary command-line application, which Crowdstrike (antivirus, effectively) kills as suspicious. I was able to unpack the PKG file and figure out what it would do and undo that manually, but anyone who isn't a reasonable expert at MacOS administration will just have a process from "Shanghai Dewav IoT Technology Co., Ltd" running on their computer, as root, for eternity.There is just no need for this at all, and it's genuinely suspicious.

This is a quite simple temperature logger. Many of these originated during Covid to record the temperature of vaccine shipment and guarantee that the temperature was maintained throughout the shipment. That is the reason these have the stop disabled by default and barcode. Of course, there are many other uses for these but that is the original intention, so don't complain about that.This logger does what it says. The parameters can be set/changed from the software which is simple and intuitive. However, I had few times when the software didn't recognize the device and had to reconnect it. Other than that the device logged the temperature well at set interval. Temperature accuracy seemed fine. In my test it didn't fail once when used from -20°C to +50°C. Getting the report in CSV or PDF without the software is good option.Overall it work as intended, you should know its intended purpose and your use case.

In theory these are a good idea. In practice however, they are pretty frustrating. Didn't realize that you could only use them with their PC/Mac software. Couldn;t hardly set them up without it. My main PC runs Win 11 and the software kept bugging out. Used an older laptop with Win 10 and it fared better. Tried my wife's Mac and found the software to be nearly unusable so went back to my Win 10 laptop. Finally got them all set up but they just feel like a beta product that still needs development..

Works great, high accuracy, and love that it also collects humidity data. If you're looking for a temperature logger this is a great choice. There are also a lot of customization options if you download the frigga software (change the units F/C and set the recording delay).

We have an insulated shipping container that we heat with a small 750w heater. It's been very useful to see how below freezing temps effect the internal temps of the container throughout the day. Very happy with It's performance.

The temperature and humidity loggers keep track of temperature and humidity automatically. I configured them with the Windows application Frigga Data Center. Once installed, I plug in each logger and configure them to certain temperature and humidity thresholds, the measurement interval, whether there should be a delay when I press the start button, whether I can restart logging, and whether to activate the stop logging button on the device. I always configure the loggers with restart logging allowed. I press the start button for five seconds to start logging. Once logging is done, I can plug the device into my computer again to read the created PDF or CSV file without having to open the Data Center application again. It saves me time because I don’t have to personally check the temperature and humidity constantly.
