Control your light or Access control by voice commands. Wiring Instructions Power Supply: Use USB 5V or DC/AC 7–32V (choose one) Function: This is a dry contact relay switch — it does not output any voltage on the control side. You can connect the output (control circuit) to either: DC 0–30V, up to 10A , or AC 90–250V, up to 10A . The relay can be wired as: NO & COM for normally open operation, or NC & COM for normally closed operation. Quick to Access 2 Working Modes Self-lock mode: Works like a regular switch — press once to turn ON and stay on, press again to turn OFF . Inching mode: Turns ON when activated, then automatically turns OFF after the set time (1–3600 seconds) The device works in self-locking mode by default. How to set inching(jog) time 1-3600s? To set the jog/inching time Open the device control page in the Smart Life app . Go to Timer → Inching . Select the desired time (from 1 to 3600 seconds ). Time unit: seconds (1s). Tap Save to confirm. How to Connect with Access control? Wiring Description (Access Control / Inching Mode) Power Input (7–32V): Connect the positive (+) and negative (–) wires from the power supply to the input terminals on the module. → This part provides working power for the relay module itself. Output Terminals (NO & COM): The NO (Normally Open) and COM (Common) terminals act as a dry contact output, just like a traditional push button. → Connect these two terminals to the two ends of the access control push switch (or any other device input that needs a momentary signal). Operation: When the relay is triggered in inching mode, NO and COM will short-circuit briefly (according to your set jog time), simulating a button press to activate the access control system. Q: Why did my device fail to pair? A The device may not be in pairing mode. Your Wi-Fi name or password may contain special characters (such as @, #, &, *). MAC address filtering might be enabled on your router. Test Tip:Use two phones — one to create a Wi-Fi hotspot and the other to pair the device.If pairing succeeds, the issue is likely with your router settings. Q: Does the device support 5GHz Wi-Fi? A: No, it only supports 2.4GHz Wi-Fi. If your router uses dual-band (2.4G + 5G) combined , please go to your router settings, separate the two networks , and set different passwords for each.

Review: Works like a charm. - It does exactly what I need it to do. I have a gate 300 meters from the house. Now I can open and close remotely. It connects to wifi perfectly
Review: Reliable inexpensive hardware to control remotely any low voltage actuator - Very easy to install the app. I can control my gate through my phone app. Definitely worth the money. Good quality, it’s all you need for turning something on/off remotely. It works with low voltage devices, such as garage door remotes or relays. I like the NO/NC option offered, you can control both types of relays. Connectivity is good, it’s far away from the wifi router, but works like a champ.
