    • STIHL Smart Connector Zoom
      STIHL Smart Connector

      STIHL Connected is a cloud based system that enables professional users to digitally manage machine fleets and work assignments.

      This is managed by the STIHL Smart Connector - a sensor with a diameter of just under 5cm, which is mounted on the tool. It can be mounted on petrol, electric or battery-powered tools where it records and saves the operating hours while the motor is running and transmits this information via Bluetooth® 4.2 to the STIHL connected App (the smart connector can be mounted on non-STIHL tools too). The Smart Connector offers entirely new functions and services, as a basis for device management both in your home garden using the STIHL connected App, and for managing your machine fleet using the STIHL connected Portal. The STIHL connected Portal gives you a detailed overview of the status of your fleet of tools, as well as information such as duration of use on a particular work assignment.

      You can view power tool availability, analyse machine usage; plan and manage work tasks with associated resources; and analyse machine data, which you can then use to optimise your daily work processes. The Smart Connector also provides information about upcoming tool maintenance and, if needed, the system can arrange a workshop appointment directly with a STIHL Approved Dealer. Service-related tool data can also be shared with the dealer with your permission, so they can plan the servicing work in advance and order any necessary spare parts. This can shorten service times so the tool is quickly ready for use again.

      STIHL Connected is an intuitive way to manage your machine fleet and workload intelligently and efficiently. Visit: STIHL connected FAQs to find out more.
