Getting started with prebuilt PCBs

If you bought a prebuilt PCB, you can follow this step-by-step guide to set up your HCP-Bridge with your Hörmann garage door.
These instructions focus on the Gifford47 PCB version, but the process is very similar for all other board versions.

🔌 Installing Sensors

If you want to connect temperature sensors or any other sensors, follow these steps carefully:

  1. Solder pin headers to the dedicated sensor pads on the Gifford47 PCB.
    Make sure the pins are properly aligned and the solder joints are clean and solid.

  2. Attach the sensors to the corresponding pin headers according to the pinout.

  3. Reinstall the PCB into your SupraMatic unit.

  4. Upload the correct firmware to your board:

    • Without sensors → HCP_Giffordv2a.bin or HCP_Giffordv3a.bin
    • With sensors (any type) → HCP_Giffordv2b.bin or HCP_Giffordv3b.bin

⚠️ Note: The “b” firmware variant is required whenever sensors are present — even if only one is connected.

What you need

  • Prebuild PCB with HCPBridge Firmware installed (installed out of the box on gifford PCBs)
  • USB-C power supply (PCB-Revision >=3)
  • 3.3V power Supply (min. 300mA)

Initial configuration

1. Connect the PCB to power via the USB-C connector/ 3.3V power supply and wait a few seconds. the LED will be lit.

2. Search and connect to the WIFI Network called "HCPBRIDGE" the PCB creates with a phone or pc.

3. When connected, open a webbrowser and go to the WEBUI under the following url : http://192.168.4.1

Initial WebUI

4. Open the "Basic Configuration" tab and enter your WIFI and MQTT credentials, then click save.

Note: The wifi password has to be ASCII chars between ASCII 32-126.

Tip: To disable the wifi AP just uncheck the "Enable wifi AP" checkbox and save

basic config

5. The PCB should now be connected to your wifi. You can now check if it is reachable from your home network and if it connected to your MQTT Server.

Installation

1. connect the PCB with a RJ12 cable to the BUS port on your Hörmann garage door motor (image below, see green arrow).

Garage Motor

2. Figure out how to execute a bus scan on your model, see info below or have a look in your motors ueer manual.

ProMatic Serie 4

Use the bottom dip switch (see image above, blue arrow) and toggle it, this will start the buss can.

SupraMatic E/P Serie 4

Use the Buttons to navigate to the menu 37 and excecute the Bus Scan, see here: Tor7.de - Supramatic Bus Scan

3. execute a bus scan on your garage door motor, this should make the PCB light up (3V3) and blink rapidly (RS485 module)

4. if the bus scan was succesfully you can connect to the WEBUI and control your garage door motor, it should look like in the image below.
