Looking for a Centurion D5 Evo Home Assistant installation guide? This Smart Gate Controller installation guide walks through compatibility checks, safe wiring, WiFi setup and ESPHome integration using real installation photos. The HomeAutomations Smart Gate Controller provides local gate control, status monitoring and Home Assistant automations. Download the Smart Gate Controller V1.3 PDF manual for the full device-specific instructions.
Before you begin: This is a practical overview, not a substitute for the motor-specific wiring diagram or the supplied product manual. Gate motors and controller revisions differ. Isolate power before wiring and confirm terminal functions and voltage with the manufacturer’s documentation.
What can the Smart Gate Controller do?
- Open and close a compatible automated gate from Home Assistant.
- Report gate status through the controller’s status input, where supported by the motor.
- Enable notifications and automations, such as an alert when a gate remains open.
- Provide local control using ESPHome and Home Assistant, without requiring a separate cloud subscription.
- Support pedestrian opening on firmware and hardware versions configured for that feature.
Remote access when away from home depends on your Home Assistant remote-access configuration; the controller itself does not automatically make your gate internet-accessible.
Centurion D5 Evo compatibility and installation requirements

The Smart Gate Controller product listings identify Centurion D5 EVO, D5-Evo SMART+ and D6 Smart models among their supported motors. Confirm your exact motor model, control-board revision, power supply and terminal layout before installation. For any other motor, contact HomeAutomations before purchasing.
Important: The current product listings advise against using this controller together with a Centurion G-Ultra. Do not assume compatibility based only on the motor’s supply voltage.
Choose the right controller
| Standard Smart Gate Controller | Smart Gate Controller + External Antenna |
|---|---|
| Onboard WiFi antenna; suitable where reception at the motor is reliable. | External antenna included; useful when the gate is farther from the access point or the enclosure affects reception. |
| View standard controller | View external antenna model |
Actual wireless performance depends on distance, obstacles, antenna placement and interference. Check WiFi signal strength at the installation location before choosing.
What you will need
- A compatible gate motor and the correct Smart Gate Controller model.
- Smart Gate Controller Installation & User Manual (V1.3) – download PDF and the motor manufacturer’s installation documentation.
- A suitable DC supply as specified for your exact controller and motor installation.
- Reliable 2.4 GHz WiFi at the gate.
- A working Home Assistant installation with ESPHome integration.
- Appropriate insulated wiring and tools; professional assistance if you are not comfortable working on gate-motor electronics.
Step 1: Identify the motor terminals

With the gate motor safely isolated from power, identify the terminals for power, common/ground, trigger or push-button control, and any supported status output. Do not wire by terminal name alone: assignments vary across motor families and board revisions.
Step 2: Mount and connect the controller


Position the board securely inside a suitable enclosure, away from moving parts, water ingress and high-voltage wiring. Follow the supplied manual to connect the power input, relay contacts and opto-isolated status input where applicable. Verify polarity and measured voltage before powering the controller.
The controller and its external-antenna variant are sold without a case unless otherwise stated. Choose an enclosure appropriate to your installation environment.

Step 3: ESPHome gate controller setup with Home Assistant
- Power up the controller only after the wiring has been checked.
- Follow the controller manual to provision its WiFi connection.
- In Home Assistant, open Settings → Devices & services and add or discover the ESPHome device.
- Check that the available gate controls and status entities appear.
- Give the device and entities meaningful names, such as Driveway Gate.
Step 4: Test operation safely
Keep people, pets and vehicles clear of the gate. Test the controller’s trigger with the gate in view, then confirm that Home Assistant reflects the actual gate state. Test open and close transitions, and pedestrian mode only if your firmware includes it. Never rely on a dashboard indication alone as a safety interlock.
Step 5: Create useful Home Assistant automations
Gate left open notification
Once you have confirmed the correct gate-status entity, create a Home Assistant automation that triggers when the gate remains open for a chosen period, such as five minutes. Send a notification to your phone. Use your own entity ID rather than copying one from another installation.
Arrival and departure automations
Home Assistant can combine presence, time and gate state to assist with access routines. For safety and security, consider requiring confirmation before automatically operating a gate, especially where visibility is limited.
Troubleshooting
The controller is offline
Check supply voltage, 2.4 GHz WiFi coverage and whether the device appears on your network. The external-antenna model may help in difficult RF environments, but is not a substitute for adequate network coverage.
The gate operates but status is incorrect
Confirm the motor’s status output, input wiring and the ESPHome configuration for your exact motor and firmware. Status signalling may use pulses rather than a steady signal on some setups.
Home Assistant cannot discover the device
Check network reachability between the ESPHome device and Home Assistant, including any VLAN or firewall restrictions, and follow the pairing instructions in your manual. See the official ESPHome native API documentation for additional connection guidance.
Can I use this with a G-Ultra?
The current product listings specifically advise against using the Smart Gate Controller together with a G-Ultra. Contact HomeAutomations before attempting that combination.
Frequently asked questions
Does it need an internet connection?
Local operation through ESPHome and Home Assistant does not require a cloud service. Remote access from outside your home requires a separately configured remote-access method.
Do I need the external antenna version?
Choose it when WiFi reception at the gate is weak or antenna placement outside the enclosure is advantageous. If the signal is strong at the motor, the standard version may be sufficient.
Is an enclosure included?
The current product listings state that a case is not included. Check the product page for compatible enclosure options.
Can I install it on another gate motor?
Possibly, but confirm the motor’s electrical and control requirements with HomeAutomations before ordering.
Ready to automate your gate?
Compare the Smart Gate Controller and Smart Gate Controller with External Antenna, and contact HomeAutomations if you need help confirming compatibility with your motor.
