Sonoff Sensor for TH Origin/Elite (THR316/THR316D/THR320D) | THS01
Plug-in sensors for the SONOFF TH Origin and TH Elite temperature & humidity monitoring switches. Choose the THS01 to measure both temperature and humidity, or the WTS01 waterproof probe to measure temperature only, including in wet places. Both use an RJ9 4P4C plug that goes straight into the switch.
Color: Black
THS01 – Temperature & Humidity: Measures temperature from -40°C to 85°C and humidity from 0 to 100% RH on a 50 cm cable. SONOFF states it can simply be inserted into a TH Elite or TH Origin, with no tools or configuration needed.
WTS01 – Waterproof Temperature Probe: A stainless-steel probe that is waterproof, corrosion-resistant and rust-proof, with a 1.5 m cable so the probe can sit further from the switch. It measures from -40°C to +115°C, with ±0.5°C accuracy between -10°C and 85°C.
Who it's for / Works with: Owners of SONOFF TH Origin (THR316 / THR320) and TH Elite (THR316D / THR320D) switches who want the switch to react to temperature (and, with THS01, humidity).
Good to know: These are accessories only — they do not work on their own and need a TH Origin or TH Elite switch (sold separately). The WTS01 measures temperature only; choose the THS01 if you also need humidity.
