Case study

PumpSaver Plus: decoding the relay's infrared broadcast

A protocol reference and Python decoder reconstruct the baseband infrared register broadcast of SymCom and Littelfuse PumpSaver Plus pump-protection relays. It maps 32-bit words to voltage, current, power, settings, counters and fault history, with sample captures and decoder tests.

Requirements & limits

Prerequisites: A baseband IR edge capture is required; a 38 kHz demodulating receiver cannot capture this carrierless signal.
Prerequisites: Python 3.10 or newer is required for the decoder.
Limits: Several configuration registers and fault-code names remain candidates.
