Start with ‘IoT’

Used scenario •  Scenario = pattern of six 10 minute intervals

For example 5 4 3 2 2 2

•  The tempdif = (set – inside) temperature

•  The outtempdif = (set – outside) temperature

•  Raspberry PI selects (given a tempdif and outtempdiff) –  50% of the time: best temperature scenario –  50% of the time: alternative scenario

•  Used scenario and tempdif and outtempdiff used to select this scenario are uploaded to the server.

Minutesperrun–maintainroomtemperature Minutesperrun–maintainroomtemperature(alternaKve)

Two step process

A. Score each used scenario

B. Cluster and rank scenarios in each cluster

B. Cluster and select
