HISMART TUYA Smart 1-kanálový spínač s externým teplotným senzorom, Wi-Fi & RF, 16A, AC 85-250V

Automate your heating and climate control with the HISMART TUYA Smart 1-Channel Switch. This intelligent relay switches loads up to 16A (3500W) and integrates an external NTC temperature sensor, letting you create temperature-triggered automation scenes. Control it from anywhere via the Tuya Smart or Smart Life app, with a 433MHz RF remote, manually via the push button, or by voice with Amazon Alexa and Google Assistant. Whether you manage a greenhouse, a sauna, or a home ventilation system, this switch gives you precise control with flexible scheduling and temperature-based rules.

Why choose it?

The combination of a built-in Wi-Fi module and an external temperature sensor makes this switch perfect for creating energy-saving automations without a separate smart hub. You can set the switch to trigger when the temperature falls below a threshold, keeping your environment comfortable while reducing electricity waste. The 16A rating handles high-power devices like heaters and water pumps, and the RF remote gives you a physical backup in case Wi-Fi is unavailable.

Ideal use cases

• Greenhouse and grow room temperature control
• Sauna and underfloor heating management
• Attic fan and ventilation automation
• Electric heater and dehumidifier scheduling
• Boiler circulation pump switching based on temperature

Good to know

Installation requires a neutral line and proper grounding. The external temperature sensor is included, so you can place it in a remote location to monitor and control based on actual conditions. The switch works with the Tuya ecosystem, enabling integration with other Tuya-compatible devices for advanced scene automation. Note that the RF remote is not included; the switch is compatible with standard 433MHz RF remotes.
