SensorBlue for Android

Won’t download from I phone 7

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. Status:POSITIVE RECOMMENDATIONS

The feedback button doesn’t work so I have to leave my feedback here. Notifications of humidity and temperature falling out of range only work if you open the app. This renders them somewhat useless. The app should be kept alive in the background or something else done to ensure that notifications are always sent.

Works reasonably well for a few sensors, but with three, you have to scroll to go from the first to the last. This is ridiculously slow (Mobile air 2, so admittedly not super modern), most of the time just resulting in re-ordering the sensor windows in the list. It shows three significant digits in the reading (so two decimals at single-digit temperatures), which seems a lot when the thermometer promises 0.5°C accuracy. “Calibration” seems to just be a fixed offset, so not really a calibration, but may be better than nothing if it is used predominantly in a narrow temperature range. I’ve seen it display -1000°C when connectivity to the sensor seemed poor, maybe that’s a defect in the sensor or communication protocol. Refreshing that you don’t need to give up personal information to use it, kudos (and an extra star) for that.

I leave the app open 24/7. It always stops updating- it shows old data on the main screen, and reopening shows new data. This almost destroyed all of my products. Please prioritize this urgent fix over secondary data reporting features. I don’t want to have to analyze the thermometer Bluetooth and write my own app just to have a working product. I like many things about this app besides this issue though. edit: 2021-01-09 ok the update bug hasn’t happened in 5days. Can you give us a last-updated-at timestamp option for each sensor so we know if it’s up-to-date or not, thank you, great app.
