Energy management protocols for smart devices
Energy management protocols carry information (in both directions) to command and control, e.g., increasing or decreasing device energy consumption, scheduling device operations, providing electricity price information, reporting operating states, etc.

Global Energy Consumption of network connected devices 2010-2030
The figure shows a graph with the annual energy consumption of network-connected devices in different operating modes - network active and network standby - as well as with the upstream energy consumption of networks and data centers. By 2030, the total global energy consumption of network-connected devices will increase to about 1,000 TWh/yr. Device-related energy consumption in particular will increase significantly, whereas upstream energy consumption will decrease somewhat and account for about one-third of the energy consumption associated with network-connected devices. These and other graphs on the energy consumption of network-connected devices can be quantified using the EDNA Total Energy Model.

Models for IoT heat pumps
The graphic shows different types of models that are relevant for IoT heat pumps. Physical models are based on physical relationships, data-driven models are created using only data. Hybrid models are based on both data and physical relationships.

Products and services for IoT heat pumps
Over 40 different examples of projects and products for IoT heat pumps were collected in IEA HPT Annex 56. A distinction can be made between 5 categories: Optimization of heat pump operation, Predictive maintenance, Provision of flexibility, Commissioning of heat pump systems and Heat as a service. An example can be assigned to more than one category. The examples are available at https://heatpumpingtechnologies.org/annex56/factsheets/.
