tempi.fi vs Anchor Chain Scope & Length

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
