Description
Sonoff WTS01 temperature sensor – RJ9 (4P4C)
Precise measurement for smart automations
Sonoff WTS01 is a digital temperature sensor with an RJ9 4P4C connector, designed specifically to be compatible with the Sonoff TH range of smart relays (TH Elite, TH Origin etc.). It is ideal for temperature-based automations in homes, offices, greenhouses or technical rooms.
Key features:
Precise temperature measurement
Detects ambient temperature in real time, providing essential data for automated control of connected appliances.
RJ9 4P4C connector
Guaranteed compatibility with the Sonoff TH Elite and TH Origin models – connects quickly and securely, with no need for additional adapters.
eWeLink integration
Once connected to compatible relays, the temperature data is displayed directly in the eWeLink app and can be used to trigger automations or notifications.
Flexible use
Ideal for controlling heating, ventilation and air conditioning systems or for temperature monitoring in technical rooms.
Practical use cases
- Connected to a Sonoff TH Elite or TH Origin, it automatically switches the heating on when the room temperature drops below the set threshold and switches it off when the threshold is reached.
- Thanks to the waterproof stainless steel probe, it can monitor the water temperature of a heated swimming pool or an irrigation system.
- Installed in a greenhouse or a technical room, it sends a notification in the eWeLink app when the temperature exceeds the desired limit and can switch on ventilation.
