Rainwater tank top-up and pump protection on a level probe A pressure-based level probe keeps the 3 000 L rainwater tank between 40 % and 85 %, tops up from mains only during the cheap night window, and cuts the pump below 15 % so it never runs dry and burns its seal. wifi 3600000 ms 2026-11-07

Pipe-freeze guard: trickle the far tap and warn before the line drops to 2 °C A pipe-clamp temperature sensor on the most exposed run warns at 4 °C and opens a 0.4 L/min trickle at 2 °C, which is enough to keep a 15 mm copper line flowing through a -8 °C night without wasting more than 12 litres. thread 120000 ms 2026-10-20

Irrigation that skips a zone when the soil is already wet Six soil-moisture probes veto each zone's scheduled run. Over one summer the controller skipped 34 % of scheduled cycles and cut water use by 41 m³ without any visible plant stress on the tomatoes or the hedge line. zigbee 1800000 ms 2026-10-02

Leak-triggered main shutoff with a 4 litre flow threshold Six leak pucks plus a whole-house flow meter close the main valve when any puck gets wet, or when flow exceeds 4 L/min for 12 minutes with no fixture in use. Measured shutoff time from water contact to closed valve: 9 seconds. zwave 9000 ms 2026-08-30
