IoT Empower was formerly called ulnoiot (You will know IoT).
iotempower is the brainchild of one of the founding authors (ulno) of IoTempire. It was initially envisioned as a pedagogical tool, but is slowly maturing into a competitive product and gains industrial relevance. Apart from having a strong focus on being easy to teach, it also has a strong focus on privacy and security. It allows to build IoT solutions which don't collect user data and are very resistant to attacks.
