NIBE
Overview
The NIBE Nibe S-Series (SG Ready) is a ground source and air-to-water heat pump range designed for residential and light-commercial heating and domestic hot water. This ModbusCloud template connects over Modbus TCP and reads the active SG Ready operating state, hot water temperature, instantaneous power consumption, and accumulated energy. It also writes the SG Ready mode setpoint, enabling four operating levels from load blocking to full boost. Installers and energy managers gain direct visibility and demand-response control of NIBE S-Series heat pump operation from a single portal.
Use cases
- Monitor instantaneous power consumption to verify the heat pump stays within contracted grid capacity limits.
- Track hot water temperature over time to detect degraded heating performance or sensor drift.
- Alert on unexpected SG Ready state mismatches between the setmode command and the getmode readback.
- Report accumulated energy figures weekly to compare heat pump efficiency across seasons or sites.
