Choose the controller type
| Type | Best suited to | Main check |
|---|---|---|
| Smart tap timer | One or a few hose/tap zones | UK tap thread/adapters, pressure/flow, batteries and frost removal |
| Multi-zone irrigation controller | Existing wired solenoid valves | Zone count, transformer, enclosure, valve voltage and installer boundary |
| Hub-based garden system | Matching sensors/timers in one ecosystem | Hub range, local behaviour, account/cloud and compatible exact models |
Weather-aware watering
A controller may use forecast services, local sensors or both. Forecast-based skips are not proof that soil is wet. Check the weather source, rain/freeze thresholds, sensor support, manual override and behaviour during an internet outage.
Use water responsibly
Follow current local restrictions, avoid runoff and waterlogged soil, inspect emitters and repair leaks. Seasonal schedules need adjustment for plant, soil, shade and weather. Drain or remove equipment where required for frost protection.
Costs
Include adapters, hub, valves, enclosure, sensors, batteries, subscription and installation. No fixed saving is promised.
