The DieseRC Tuya 2 Channels WiFi Smart Switch is a compact relay module designed for DC power systems, supporting input voltages of 5V, 12V, 24V, and 36V with passive output. It operates as a two-channel smart switch, enabling individual or simultaneous control of connected low-voltage devices. The module integrates Tuya’s WiFi chipset, allowing seamless connection to a 2.4GHz home network for remote management via the Smart Life or Tuya Smart app. Built with a durable PCB and reinforced solder joints, it ensures stable performance even in continuous use environments like home automation cabinets or industrial control panels. The package includes two RF remote controls, which operate on a dedicated 433MHz frequency, offering an additional layer of convenience for local switching without needing a smartphone. Compatibility with Amazon Alexa and Google Home voice assistants expands its hands-free control possibilities, letting users integrate it into existing smart home routines. The relay’s passive output design means it can switch loads without supplying power itself, making it suitable for controlling lights, fans, pumps, or other DC-powered equipment where isolation is required. Its compact plastic enclosure is flame-retardant and ventilated to dissipate heat, supporting long-term reliability. The channel outputs support up to 10A per relay, though actual capacity depends on voltage and load type. Programming via the app includes timer, countdown, and schedule functions, which can be set without cloud dependency for basic tasks. The RF remote range is typically up to 30 meters in open areas, providing flexibility in placement.

The module presents a cost-effective solution for users needing reliable, multi-voltage WiFi switching with physical remote backup.
