Single Relay Low-Voltage WiFi Module GISE GSS-WF-DRDC — Tuya Compatible, Potential-Free Output

GISE single relay low-voltage WiFi module GSS-WF-DRDC is a compact smart relay module intended for integration into home and small-building automation systems. The device provides a potential-free (dry contact) single relay output that allows remote switching of low-voltage control circuits over a WiFi connection. It is compatible with Tuya and other Tuya-based platforms, enabling control via mobile apps, voice assistants and automation scenes without altering existing high-voltage wiring.

Advantages

The module offers a galvanically isolated, potential-free relay output to ensure safe switching of low-voltage circuits. Its Tuya compatibility simplifies pairing with popular smart home ecosystems and third-party apps. The compact form factor and low-voltage operation make it suitable for retrofit installations where space and safety are priorities. The WiFi connection supports remote control and schedule-based automation while retaining local manual control through the connected low-voltage switch.

Suitable for

• Remote switching of lighting circuits driven by low-voltage control lines
• Controlling gate or garage door control inputs that require dry contacts
• Integration with alarm, access control or intercom systems that use potential-free inputs
• Smart retrofit installations where isolation from mains voltage is required

Key specifications

• Function: single relay, potential-free (dry contact) output
• Communication: WiFi connectivity compatible with Tuya platform
• Operating voltage: designed for low-voltage control circuits (no direct mains switching)
• Form factor: compact module suitable for installation inside distribution boxes or behind control panels
• Control options: remote control via mobile app and voice assistants, local control via existing low-voltage switch

How to use

Install the GISE module in a safe, dry location inside a distribution box or near the control point, ensuring it is connected to the low-voltage control circuit only. Follow standard wiring practice for potential-free contacts: connect the dry contact terminals to the control input of the device you plan to switch (lighting driver input, gate control, alarm input, etc.). Configure WiFi and Tuya integration using the Tuya-compatible app by following the pairing procedure: put the module in pairing mode, connect it to the local WiFi network, and add it to your Tuya account. After successful pairing, create schedules, scenes or link the module with voice assistants as needed.

Usage recommendations

Verify that the controlled device expects a potential-free contact and that the module is only used within its specified low-voltage application range. Avoid connecting the module directly to mains loads. For safe installation and compliance with local regulations, consider having a qualified electrician perform the wiring and final setup.
