How a small Wi-Fi relay turns an existing autogate into a smart gate, and what to check before adding one.
📍 We serve KL, Selangor & Putrajaya.
A smart auto gate is usually an ordinary autogate with a small Wi-Fi relay added inside the control box: the relay's dry contact is wired to the same input as the gate's push button, so the app on your phone simply "presses the button". It needs Wi-Fi that reaches the gate (or a GSM module instead), a board with a push-button or start input, and the safety sensors left working. For comparison, ClickBina's autogate repair guide prices a GSM module that opens the gate by phone call at RM400 – RM900.
Most autogates already have a way to be triggered without a remote: a wall button, a key switch, or a push button inside the control box. Our autogate remote guide uses exactly that button to separate a remote fault from a gate fault.
A smart opener adds a relay with Wi-Fi (or Zigbee) next to the board. The manual for one such Wi-Fi relay (Rubetek RE-3314) describes a relay with a dry contact that can control automatic gates, wired in parallel with the control button. When the app tells the relay to close its contact, the board sees the same signal as a button press and runs its normal open or close cycle.
A dry contact is simply a switch with no power of its own on the contacts. A documented owner retrofit on a BFT gate (Arslan, 2024) puts it plainly: the relay closes or opens a switch without applying any energy to the contacts, which is why it can sit across a gate board's button terminals.
Many modern gates use rolling-code remotes. The remote guide explains that the code changes with every press, so a recorded code cannot be replayed and copy remotes usually fail. That is good for security and the reason a phone app cannot simply imitate the remote. The same owner retrofit reached the same conclusion: with a rolling-code remote, replicating the radio signal was out of the question, so the relay went onto the board instead.
Wiring to the board keeps the rolling-code remotes working as before. The app is an extra way in, not a replacement.
| Check | Why it matters | If not |
|---|---|---|
| A push-button or start input on the board | The relay connects across it | A different input or an accessory module from the gate brand |
| Wi-Fi signal at the control box | The relay is usually at the gate, not in the house | A mesh point or outdoor access point, or a GSM module |
| A spare power supply for the relay | The relay needs its own power to switch | Power from the board's supply if the manual allows, or a separate supply |
| A dry, sealed control box | Indoor-rated relays fail in a wet box | Seal the box or use an enclosure suited to outdoors |
| Working safety sensors | The gate must still stop and reverse for cars and people | Fix them before adding remote control |
Find the model name on the control board and read its manual for the push-button terminals. The owner retrofit above used the board's start terminals from its manual; every brand labels them differently.
The gate is often the furthest point from the router, behind a porch, a car and a steel gate leaf. Our smart home installation guide says nearly every unreliable smart device complaint is really a network problem, and recommends fixing coverage before buying devices.
The same guide sets a second test: what happens when the internet drops. A cloud-only relay cannot be reached from outside the house during an outage, so keep the remotes and the wall button as the everyday method and treat the app as a convenience. If Wi-Fi cannot reach the gate at all, a GSM module that opens the gate by phone call is the usual alternative.
Wireless smart-home switches are named on MCMC's device list, as our home alarm system guide notes, so check that any Wi-Fi relay carries the MCMC label.
Most Wi-Fi relays work through their own app, and many link to Google Home or Alexa, so a gate can be opened by voice or from a routine. The smart home guide's advice applies: things that must always work should not depend on the cloud. For a gate, that means the remote and wall button stay in place, and voice is the extra.
Be careful with automations. A routine that opens the gate when your phone arrives home can trigger at the wrong moment; many owners keep the gate as a deliberate tap in the app.
A phone app is one of several accessories. The autogate repair guide lists the others with published prices, and each suits a different household:
| Option | Indicative price (2026) | Suits |
|---|---|---|
| GSM module: open the gate by phone call | RM400 – RM900 | Households with many drivers, or no Wi-Fi at the gate |
| Keypad or fingerprint reader | RM200 – RM600 | Opening without any device |
| Intercom | RM300 – RM800 | Letting visitors in from inside the house |
| Replacement remote battery | RM5 – RM20 each | Keeping existing remotes reliable |

💬 WhatsApp for a quoteNo ClickBina page publishes a price for a Wi-Fi relay retrofit, so we do not print one; it depends on the board, the power supply at the gate and whether Wi-Fi needs extending.
The relay manual is clear that the line it connects to must be de-energised during installation. The gate side carries the board's own supply and sometimes mains, so this is technician or electrician work, not a DIY job on a live box.
Adding remote control must never mean bypassing a safety device. The repair guide warns against turning up the obstruction force to push through a sticking gate, because auto-reverse is what stops the gate closing on a child or a car. A gate you can close from your phone while away makes those sensors more important, not less.
