Important Notes
-
Temperature Only: Does not measure humidity.
-
Controller Required: The WTS01 is an external sensor and cannot operate independently.
-
Waterproof Design: The sensing probe is designed for wet environments. Keep the connector and non-waterproof electrical connections dry.
-
Compatibility: Designed for compatible SONOFF TH Series devices with an RJ9 interface.
-
Not a Standalone WiFi Device: Remote monitoring requires a compatible SONOFF controller.
-
Measurement Range: Do not expose the sensor to temperatures outside its specified operating range.
