This product is very similar to more well known brands such as Nest and Hive but offers users more flexibility in terms of it’s uses. We are currently looking into the use of this device to control and monitor our studio automated machinery, predominately 3D printers as some jobs require long print times and we believe that safety should be paramount with these kinds of operations. This device could be used to monitor the printer whilst printing and will give us the ability to shut down the printer once the print is completed. Also in the event the print becomes unattached from the build platform the may be stopped.
