What Do You Need to Control a Gate with Your Phone?
Start with a phone-controlled gate opener relay.
The Shelly Plus 1 costs $20 to $25. The ESP8266 relay module runs about $15. These devices connect to your gate motor's trigger circuit.
You'll need basic supplies. Get 18-22 gauge wire for $5 to $10. Grab a screwdriver and a multimeter for testing. Pick up electrical tape or heat shrink tubing for waterproofing connections.
Most gate motors run on 12-24V power.
Most gate motors run on 12-24V power. The relay draws power from your motor board. Some setups use a USB 5V adapter instead. You won't need an extra transformer.
Download a free control app. Smart Life, eWeLink, and Tuya work on both iPhone and Android. Your gate needs 2.4GHz Wi-Fi coverage. A Wi-Fi extender costs $15 if your signal doesn't reach.
Your total cost runs $40 to $60. This leaves room in your budget for safety extras. Infrared photocells cost about $10 and prevent accidents.
Step-by-Step Guide: How to Install a Smartphone Gate Controller for Under $100
This DIY smart gate controller installation takes 20 to 45 minutes. You don't need prior electrical experience. Just follow basic safety rules.
Step 1: Find the Trigger Terminals on Your Motor
Turn off the power at the breaker before touching any wires. Open your motor control box to see the circuit board inside.
Look for labeled terminals.
Common labels include "OPN" for open, "COM" for common or ground, and "TRIG" for trigger. Some motors use numbered pins like 13-14. Check your manual if labels aren't clear.
Test the terminals with your multimeter set to continuity mode.
Touch two wires across the suspected pins. The gate should cycle through open, stop, and close, just like pressing your remote button.
Take a photo of your circuit board for reference. Most motors use standard dry-contact inputs that work reliably with any relay switch.
Try a momentary push-button first if you're unsure which terminals to use.
Step 2: Connect the Relay to Your Gate Motor's Trigger Terminals
Strip about 1/4 inch from each wire end. Connect the relay's COM wire to your motor's COM or GND terminal.
These are the ground connection points. Connect the relay's NO wire (normally open) to your motor's OPEN or TRIG terminal.
This is the trigger point that opens your gate.
Add a small component called a 1N4007 diode across these two wires. Think of it as a safety guard that protects your relay from electrical spikes. The diode has a stripe on one end that shows which way it should face.
Attach the wires using either solder or screws.
Your relay needs power to work. Most draw power from your motor board's 12-24V output. Some use a micro-USB charger with a weatherproof case instead. Check which wire is positive and negative before connecting.
Cover all wire connections with gel-filled wire nuts. These protect against rain and moisture better than regular wire nuts. Put the relay inside your motor box where it won't touch any moving parts.
Test everything before closing up.
Turn the power back on and press the button in your app. You should hear a clicking sound from the relay. Your gate shouldn't move yet. This test makes sure your wiring is safe and correct.
Adding the diode safety guard prevents almost all relay problems. The setup works exactly like your remote control. Your gate motor can handle much more power than this relay uses.
Step 3: Connect to the App
Scan your relay's QR code to download Smart Life or eWeLink. Press the relay button until the LED flashes blue. This puts it in pairing mode.
Connect through your phone's hotspot feature. Enter your 2.4GHz Wi-Fi password when prompted. The relay joins your home network within seconds.
Rename the device to something clear, like "Driveway Gate." Now you can set up useful features:
-
Create timers - Set a "Guest Access" schedule that opens the gate at specific times
-
Add auto-close - Schedule automatic closing after 30 seconds
-
Share access - Give family members their own login through the app
-
Set up geofencing - The gate opens automatically when you get within 100 meters of home
-
Get updates - The app downloads security patches over Wi-Fi without any rewiring
You can remove anyone's access anytime without collecting physical remotes.
Step 4: Test the Range
Restore full power to your system. Walk 50 to 100 meters away in an open space, then tap "Open" in your app.
The relay should respond instantly. Most ESP and Shelly relays reach 400 meters without walls blocking the signal. Buildings and trees will reduce this range.
Run these tests to confirm everything works:
-
Cycle your gate five times - Test open, close, and stop commands
-
Adjust timing - Set auto-close delay between 5 and 60 seconds
-
Check range - If the signal is weak, install a $15 Wi-Fi extender in weatherproof conduit
-
Verify weatherproofing - Test your enclosure during rain if possible (look for IP65 rating)
-
Review security logs - Check the app to see who opened the gate and when
Add end-switch verification if your motor supports this feature for extra safety.
Signal issues are uncommon when you use the right Wi-Fi frequency. The most common mistake is selecting 5GHz Wi-Fi instead of 2.4GHz during setup.
Always choose 2.4GHz for outdoor devices since it penetrates walls and travels farther than 5GHz.
Safety First
Always turn off the power before touching wires. Use insulated tools rated for electrical work. Follow these safety steps:
Step 1: Add obstacle sensors - Install $10 infrared photocells that reverse the gate when blocked
Step 2: Weatherproof the relay - Use an IP67-rated enclosure for rain and heat protection
Step 3: Stay low voltage - Work under 30V only and never touch live high-voltage wires
Step 4: Check local codes - Verify permit requirements and consult an electrician for gates over 500kg
These precautions prevent the vast majority of DIY accidents reported in home automation communities.
Can I Use Siri, Alexa, or Google Assistant to Open My Gate?
Yes.
These relays work great with voice assistants. Just say "Alexa, open the driveway gate." The command works instantly.
Set up routines for multiple actions. Create an "Arriving Home" routine that opens your gate and turns on porch lights together. Google Assistant handles similar automations through its app.
Siri requires extra steps.
Use Homebridge software or IFTTT applets to bridge the connection. Advanced users can flash Tasmota firmware for direct HomeKit support. You can ask "Hey Siri, show me the gate" for live video with compatible camera systems.
Geofencing makes everything hands-free.
The gate opens automatically as you approach. Two-factor authentication in the app keeps access secure. This works perfectly for deliveries or family members who don't carry phones.
Why Choose a Dedicated Kit vs. a Cheap Generic Relay?
Generic relays cost about $20. They work with any motor brand universally.
Open-source firmware lets you create custom automations. You'll need DIY skills to figure out wiring on your own.
If you prefer a complete system instead of upgrading your existing motor, Gatomate offers full gate opener kits. These include everything from the motor to sensors and controls.
They come in electric or solar-powered options for properties without power at the gate. You get single swing, double swing, and sliding gate systems with 24/7 technical support.
Pick generic relays when you want to upgrade your current motor for under $100.
Choose a complete system if you're installing a new gate or replacing an old motor entirely. Generic relays fail less than 5% of the time when you install a protection diode.
Complete systems offer professional installation support for homeowners who prefer expert guidance.
Is the $100 Smart Gate Upgrade Worth It?
