TR-71wf Individual Wi-Fi Temperature Data Logger
Please note that the manufacturer has replaced the TR-71wf with the TR-71wb.
The TR-71wf is a temperature data logger that can monitor two temperature zones, while the TR-72wf is a temperature/humidity logger. In addition to the basic features of T&D's standard data loggers such as battery operation and USB communication function*1, the TR-71wf/72wf supports communication with mobile devices and can be used without a PC. By using T&D WebStorage Service*2, a cloud service provided by T&D free of charge, it is possible to access stored data anytime from anywhere.
*1: An optional USB communication cable (sold separately) is required.
*2: To carry out the auto uploading of recorded data to T&D WebStorage Service, it is necessary to have Internet access via a wireless LAN and a T&D WebStorage Service User ID.

It works so well. I can check temps on my van and when I return to the shop within range of wifi, it uploads to the website automatically. Incredible!
