Sensors & Accessories for Weather Stations
Expand a compatible weather system with add-on sensors and accessories. Start with soil moisture (WH51) or lightning detection (WH57), then compare compatible probes and expansion hardware as the catalog grows. Complete stations and gateways live under Weather Stations; garden watering and frost use cases live under Garden & Irrigation; connectivity questions live under Smart Weather.
What to look for
Answer these before buying an add-on sensor.
- • Do you already have a compatible gateway or console?
- • Are you adding soil moisture or lightning monitoring?
- • Does your RF region/frequency match the sensor and hub?
- • Do you need one zone or several sensor zones?
- • Do you want a complete station or only an add-on sensor?
