Dual-Relay Smart Temperature Controller for Carboy Fermenters, Greenhouses & Terrariums — Tuya/Smart Life App (Energy-Saving)

Compact smart temperature controller with dual relay outputs for simultaneous connection of refrigeration and heating devices, ideal for carboy fermenters, greenhouses, terrariums and other temperature-critical setups. The unit features a clear digital display that shows the real-time temperature plus the programmed high and low setpoints. Temperature readings can be shown in Centigrade or Fahrenheit. Built-in high and low temperature alarms alert you when conditions move outside the set range. Remote monitoring and control are supported via Smart Life or Tuya Smart App, while local configuration is possible using the device’s onboard buttons — and the controller will continue to operate even without WiFi.
