The module connects to your WiFi network and pairs with a compatible smartphone app, allowing you to monitor and adjust temperature settings remotely from iOS or Android devices.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use a different temperature sensor with this controller?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. While the included NTC10K waterproof probe (0.5m) covers most use cases, the module also supports 18B20 digital sensors for expanded flexibility in different environments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the Backlash Temperature setting used for?\u003c\/h4\u003e\n\u003cp\u003eA: The Backlash (hysteresis) setting prevents the relay from rapidly switching on and off around the target temperature. For example, in heating mode with a set point of 30°C and a backlash of 5°C, the relay turns on at 25°C and off at 30°C — protecting your connected equipment from wear caused by rapid cycling.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What devices can I control with this WiFi temperature controller module?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This module can control any heating or cooling device that runs through a relay switch — including space heaters, heat mats, fans, refrigeration units, aquarium heaters, fermentation temperature controllers, and more — as long as the load does not exceed the 10A relay rating.\"}}, {\"@type\": \"Question\", \"name\": \"Does the WiFi remote thermostat work with a smartphone app?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
