The ability to connect with multiple devices of different nature in real time, is exactly what we need at our work place because it allows us quickly solve problems that would require other tools or methods more complex than this one.
There's not so much features as I expected but there were some good ones like the option to define which device will be used by a specific user (e.g., only allow access to an employee when he/she connects his phone). In particular we use this tool to create dashboards to visualize data from sensors placed around the factory where employees perform their daily tasks. This was very helpful during production processes and allowed me to understand if everything went well and how people could improve certain aspects of the process without interfering others.
