About This
- [Widely Used in Heating and Cooling Devices]: Single-channel WiFi smart temperature controller, supports 85-250V wide voltage or Micro USB 5V power supply, WiFi remote monitoring, and intelligent temperature control. It can be connected with heat pumps, water heaters, and other temperature control devices. Suitable for home brewing, fermentation, breeding, incubation, and greenhouse monitoring. Please do not exceed the maximum load current of 10A (high-power devices require an AC contactor).
- [Multiple Remote Control Functions]: Place the device within 7 meters of the router and add it to the Smart Life or Tuya App. No matter where you are, you can turn your appliances on/off from anywhere via the app, in both manual and automatic modes. You can also use Bluetooth for close-range operation when offline, and it supports pairing with a fixed-code 433MHz remote control (sold separately).
- [Flexible Timing and Temperature Control]: Supports scheduled device on/off, offering three control settings: timer, delayed off (jog), and countdown. Supports preset temperature values to automatically control device on/off, achieving precise and stable temperature control, easily automating device operations, and improving efficiency, product quality, and overall performance.
- [Temperature Monitoring & Sync Status]: Monitor temperature in real time, and the app keeps daily/monthly/yearly records of environmental temperature and device on/off history. Switch between °C/°F and calibrate temperature for accurate display. The on/off status of appliances is instantly reflected in the app, so you can see their running status in real time.
- [Device Sharing & Voice Control]: Share control and group control: You can share the device with up to 19 users to control it together, remotely managing your smart home. Voice control: After setting up with the Smart Life or Tuya App, link it to voice assistants like Amazon Echo or Google Home to control your appliances directly with voice commands.

SMART HOME FAQ
Yes — many modern devices support multiple platforms.
Matter-certified devices can work across Alexa, Google Home, and Apple HomeKit at the same time.
Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
Most homeowners start with:
Smart Security Cameras
Smart Door Locks
Smart Thermostats
Smart Plugs
Video Doorbells
Yes.
Smart thermostats and smart plugs help reduce wasted energy by automating heating, cooling, and power usage.
It depends on your ecosystem.
