Description
TOVTH is a compact 18 mm DIN-rail smart temperature and humidity switch for AC and DC loads in residential, commercial and industrial panels. It integrates a digital TH sensor, display and relay output in one module, providing continuous environmental monitoring together with automatic on/off control. Designed around the Tuya / Smart Life ecosystem, it brings intelligent environmental management into the same platform as your other smart energy devices.
Accurate temperature & humidity monitoring
The built-in digital sensor measures temperature and humidity in real time, with adjustable units (°C/°F) and a clear front display for instant reading. Typical working ranges cover approximately -25–100 °C and 0–99 %RH, allowing the device to handle everything from indoor comfort control to equipment-cabinet protection. Users can define upper and lower limits for both temperature and humidity so that loads are switched exactly when required, avoiding over-heating, condensation and corrosion risks.
Intelligent control & smart connectivity
Depending on the model, TOVTH supports Wi-Fi, Zigbee or LTE Cat.1 communication through the Tuya / Smart Life platform, enabling app-based configuration, remote switching and integration into smart scenes. Once connected, you can change TH thresholds, view status, receive abnormal-condition alerts and link TOVTH with other smart devices—for example, starting exhaust fans when cabinets get too hot, or driving dehumidifiers when humidity rises. This two-way connectivity turns a simple TH switch into part of a full smart distribution and building-automation system.
Robust relay output & electrical design
Behind the smart functions is a durable relay output capable of switching typical AC loads up to 16 A at 100–240 V AC (AC-1) or DC loads up to 10 A at 5–30 V DC, making it suitable for fans, heaters, valves and other auxiliaries. The device is designed for standard 35 mm DIN-rail mounting, with clear wiring terminals for line, neutral, DC supply and load, simplifying installation in new or existing panels. Flame-retardant housing and clear safety warnings help ensure reliable long-term operation in demanding environments.
Application scenarios
TOVTH is ideal for smart distribution boxes, equipment cabinets, server rooms, greenhouses, warehouses, animal farms and any space where temperature and humidity must stay within a safe window. In smart homes it can keep wardrobes, storage rooms and basements dry; in commercial and industrial sites it protects switchgear, instruments and electronics from overheating or damp. Working together with Tongou smart breakers, meters and gateways, TOVTH forms a key building block in a complete intelligent power and environmental-control ecosystem.
