"CIRCUTOR has over 40 years’ experience working on the design and manufacture of units for improving energy efficiency: electrical energy, power quality measurement and control units, industrial electrical protection, reactive energy compensation, and harmonic filtering. CIRCUTOR owns a wide portfolio of connected energy control and metering devices. Despite the diversity of proprietary and off-the-shelf data protocols, Thingsboard has made it easy to accommodate most of our products in a common data platform. I am deeply impressed by the dynamism and professionalism of the Thingsboard team. I appreciate greatly the ability to attend our technical suggestions and adopt them in the form of new functionalities. I highly recommend Thingsboard for its reliability, its flexibility and above all, the quality of the product and its technical service."
