This API is created as part of the project that concerns the development of the Vertical Industrial Solution "Smart City - Environment", in the framework of "Pleione: Pleiades Internet of Everything", launched by the "Pleiades-IoT Cluster".

The objective of the project is the creation of a smart solar heater for domestic use, granting the user visualisation of heater sensor and environmental data and remote access to its management.

The Pleione Smart Water Heater System collects domestic use of water heater data, creates the basis of information for energy consumption and savings towards sustainable water heating improving the quality of life of citizens.

To achieve the project's objective, the System leverages new low-power IoT technology networks, such as the public 0G network and low power sensors on high-end solar water heaters at the rooftops of home buildings. Thus, it features the best long term quality with the smallest possible carbon footprint concerning efficient use of energy and computing resources.

The data can be used for the following purposes:

• Active and continuous information of water heater energy usage and cost-of-living savings because of solar energy.
• Household well-being.
• Formulating water heater usage and trends of households for energy provider risk assessment.
• Monitoring maintenance and storage conditions of the water heater tank locations – rooftops.
