I’m a fully certified electrical/electronic/ mechanical engineer so this absolute truthful evaluation!
1st, the device and the software applications as specified is fully functional. Meets all normal requirements for measuring and data logging of the specified temperature and humidity range (on batter power) as specified by the mfg!
2nd(A), the operational learning curve will require a little more dedicated time in order to FULLY understand and operate the device. (As evident in the previous reviews, this was not done properly by the users)!
2nd(B), however documentation as well as application layout screen need to -clearly- identify “button” areas that will activate recall of data logged information and historical capture features, both options are fully functional that is not evident on the application display screen.
3rd, the device is NOT electrical radiation protected! Mounting the device in proximity to high frequency electrical signals will interrupt Bluetooth communication with the device - however the device will continue to data log T and H information correctly and must be removed to down load data. Area's such as in computer cabinets, electrical panels, and near power out let’s, should be prohibited.
4th, battery operation (drain) excellent (still in operational testing) plus 4 months and counting.
5th, out the box calibration is sufficient and applicable!
6th Bluetooth range is at spec.
7th, durable in design and fabrication.
Recommendations:
-Identify button areas on application to display recorded (sync) data.
-add optional holder enclosure other than magnets. Example rubber housing with attachment holes.
Comments, initial purchases were two (2) units to test and verify. Now purchasing additional four (4) units to complete project.
