Tuya TYW0 4ch RF 4 Channel Smart Relay Switch with Temperature Humidity Sensor
For homeowners who want to automate climate control for their basement workshop or garage, this 4-channel smart switch offers precise environmental management. While many smart switches focus on basic on/off functions, this device transforms temperature and humidity monitoring into proactive home maintenance.
The waterproof sensor detects subtle changes before they become problems—like alerting you when humidity rises in your laundry room, preventing mold. You can set the switch to automatically turn on a dehumidifier or fan when readings hit your preset values. With Alexa compatibility and the Tuya app, you get instant notifications and voice control from anywhere.
Schedule up to 8 tasks to optimize energy use, such as activating a space heater before you enter your cold garage. The fire-retardant enclosure and 3500W max load ensure reliable, safe operation for demanding applications.
