On April 9 we will meet for already the 5th. IoT & Built Environment conference, since 2015 a MeetUp. Each year since its start in 2011 we focus on a theme; this year’s will be Ethics & Privacy. Given the rapid development of IoT the need for discussing its consequences is more important then ever; the focus is still too much on technology and/or economic/control issues. Many issues involved will change our society, change the ways we live and act, also within our homes which still are known/labelled as private space. A debate on future values therefore is of utmost importance.
