At LightFi I was Lead UX/UI designer designing dashboards for different end users from scratch. I conducted user interviews with engineers, building managers and building visitors to see what the most important data points would be for them. This was then translated into a simple, easy to navigate dashboard design.
In the case of office managers or engineers they needed lots more data points and alerts to manage malfunctions, heat or air quality issues fast. In the case of the engineer they had an extra add on to help them install different kinds of sensors in the buildings.
