While the real-time monitoring system is useful for the daily basic control of the house, a historical interface can provide insight into the trends and behaviour of the users. The ICT infrastructure provides a graphical interface for that, which is based on the open-source platform Grafana. Using this interface, historical records of consumption and actuation, weather conditions or environmental measures in the rooms can be consulted. All the information is stored in a database (CrateDB), so the data cannot only be used locally, but 3rd party application can directly query the database for more advanced tasks such as the training of a machine learning models or data analytics.


    Connections to the 3 supply rings available in the house are distributed around the rooms. Three types of connectors can be distinguished, from left to right: - DC connector for voltages of 24 or 48 V (black). - AC plugs 230 V, 50 Hz. - DC connector for voltages between 400 to 500 V and arc protection (blue).

    The parking sensors will be placed outside the IoT Microgrid Laboratory. They inform about the vacancy status of a parking spot as well as giving a temperature measurement. These data can be used for scheduling the charging of electrical vehicles, as one charger will be installed in the premises connected to the other resources such as battery, wind and solar production.

    This sensor provides measurements of humidity and temperature in the living room area. It is manufactured by the Danish company Develco and has the following features: - Humidity Sensor up to 1% resolution - Temperature sensor up to 0.1-degree resolution - Zigbee HA certified.
