What SI Pool does
Dry running is the number one cause of pool pump failure worldwide — caused by suction loss, a clogged skimmer basket, a closed valve or low water level. SI Pool's current transformer watches the pump draw continuously and trips the circuit before the motor burns out. Pool pump replacements routinely cost R3,000–R8,000 installed. This protection runs silently every time the pump is on.
Set a target temperature and walk away. SI Pool brings the heat pump on and off to hold it — with hysteresis to prevent short-cycling, and a pump-running interlock to keep things safe.
A dirty filter restricts flow, which drops the pump's wattage. SI Pool tracks this continuously — when draw falls below your clean threshold, it alerts you. Backwash only when the filter is actually dirty, not on a fixed schedule. A typical backwash uses 400–600 litres; doing it on demand instead of weekly saves thousands of litres of water every year. Filter health is also critical for water chemistry — a blocked filter means poor circulation and chemicals that don't distribute properly.
Two configurable daily run-windows handle filtration on autopilot. Run-now and off overrides are one tap away whenever you want them.
The control panel runs on the device itself at http://si-pool.local — no app store, no cloud account required for local control. Always accessible on your home network.
The same dashboard, reachable from anywhere via a managed encrypted tunnel. No port-forwarding. No fuss. First 12 months on us.
Auto MQTT discovery — every entity appears in HA the moment a broker is configured. Pool temperature, pump status, filter health — all as native HA entities. No YAML to write.
Wall-mounted in your plant room. 220 V supply. The IP65-rated enclosure is installer-friendly with enough internal clearance for clean cable management.
