EH-IoT is an EIT Manufacturing activity that proves self-powered IoT sensing for industry and energy. Led by TEGnology, the project pairs a curved thermoelectric generator with micro-storage and ultra-low-power radios so retrofit sensors can operate without batteries or mains wiring. Prototypes are under test at three sites: a solar-panel field in Portugal, a heat-exchanger line in Sweden and a domestic solar-heating loop in Israel, validating performance across different conditions.

Peer Stritzinger GmbH supplies the GRiSP Nano reference node and the embedded firmware that manage wireless communication and power-aware control. Our contribution ensures the harvested-energy sensors report reliably to cloud dashboards and gives equipment makers a clear blueprint for scaling battery-free monitoring across their assets.
