About this app

tempi.fi's wireless temperature and humidity sensors record a new reading every minute using best-in-class Swiss made temperature and humidity sensing components, sync directly to your smart phone, fit almost anywhere, and last longer than a year on a single coin cell battery.

They are ideal for monitoring refrigerators, freezers, children’s rooms, animal & pet conditions, wine cellars, greenhouses, senior living conditions, freezing pipes, art collections, cigar humidors, chicken incubation, musical instruments and more…

With this app, you can connect and setup one or more sensors, continuously monitor temperature and humidity, get notifications when the temperature or humidity is out of range, store a virtually unlimited history, and export data in CSV format.

How it works:
• Automatically setup your sensor by holding it over your phone or tablet
• Name your sensor and set your desired conditions (if any)
• When in range, the app will automatically upload the sensor data
• If temperature or humidity is higher or lower than desirable, you get an app notification
• View historical data and create reports anytime

The unit works great and the app works fine with it. it's easy on the batteries as well although I don't know how you change the battery in the unit. The updates instantly almost continuously and that's really nice. It's grafs(history, made me a much better cigar keeper and is helping me build a active cigar box. I'll use tec1-12706 chips for heatind and cooling and DIYmore boxes for temperature and humidity control.

When the compartment of my new refrigerator seemed colder than normal though the thermostat indicated that the temperature was 38 degrees (even though the milk was freezing), I began researching temperature monitoring systems. Tempi.fi ticked all the right boxes and I've been using it for two days to monitor the refrigerator's compartment. The minute-by-minute data export CSV file showed a dramatic story of wild temperature swings over 48 hours -- certainly unhealthful for food or, more importantly, insulin storage. I've cross checked the tempi-fi real-time data on my smartphone with a standard thermometer placed in the compartment with 100% agreement between the two. The score? Tempi;fi 100 -- Refrigerator 0.

It works. But it shouldn't be advertised to monitor room temperatures. What's the point in sending a notification that it has exceeded my temperature limit if I have to be in the room to get the notification.
