STIHL Smart Connector
The STIHL Smart Connector forms the basis for using all STIHL connected functions. These functions can be used via both the STIHL connected App and the STIHL connect Portal. Once correctly attached to a STIHL power tool or another manufacturer’s power tool, the STIHL Smart Connector records operational hours while the machine is running, stores them and transmits them to your smartphone via Bluetooth as soon as it is within range. The data received in the STIHL connected App is transferred to the STIHL Cloud when there is an internet connection. The data is stored there in compliance with data protection regulations. The STIHL connected App and STIHL connected Portal allow you to access your power tool data at any time. STIHL connected opens up new avenues for professional users to obtain a convenient and transparent overview of their own power tool fleet. At the same time, STIHL connected provides information including operational hours, power tool status including reminders of overdue maintenance, the last known location, and whether or not the power tools are currently nearby. For professional users, this means improved digital fleet management, more efficient processes within companies, and even closer contact with STIHL dealers. Private users can also use the system to keep an eye on their power tools and carry out maintenance at the right time.
