How Grewa works
A good pressure pump with our software wrapped around it. The pump gives you steady water; our firmware, our backend, and our leak-detection algorithm make it watch out for you.
From the pump up
A Grewa pump is five layers: the pump itself, our firmware, an off-the-shelf wireless module for connectivity, Grewa's own backend and leak algorithm, and the app. Only the connection is off-the-shelf; the rest is what we built.
How the leak detection works
When water is quietly escaping, the pump nudges back on more often than it should, even overnight. Grewa learns your pump's normal quiet-hours pattern and watches for that tell-tale extra cycling, then flags the signature of a slow leak so you can check before it becomes a problem.
Open, and honest about it
Your pump's data is yours: read it through our documented API and pull it into Home Assistant. The wireless module is a proven off-the-shelf part; the pump engineering, firmware, leak algorithm, backend and app are Grewa's.
