Got a 433 MHz remote whose brand isn't in the compatibility list? With CustomMatch — RF-HUB's universal learning feature — you can record any 433 MHz signal and have RF-HUB transmit it again. The feature works with most simple on/off remotes, garage door openers, alarms and similar devices.
What you'll need
- An RF-HUB connected to your network
- The remote you want to record
- A web browser on the same network as the RF-HUB
Step 1 — Enable the RF menu
The RF menu is hidden by default. Open Settings → Advanced and tick Custom RF signals. Click Save and reload the page.
Step 2 — Open the RF-HUB web interface
Open a web browser and go to the RF-HUB's IP address (e.g. http://192.168.1.50/). You'll find the IP address on the Info page.
Step 3 — Go to the RF tab
Click Settings → RF in the menu. You'll land on the Record signal page.
Step 4 — Press the remote's button
Hold the remote a few decimetres from the RF-HUB and press the button you want to record. When the RF-HUB receives a signal it appears immediately on the page with timestamp, signal type and a hex string.
Press the same button 2–3 times to make sure the signal is stable (same hex value each time).
Step 5 — Open the signal in "Replay"
Click the recorded signal in the list. RF-HUB then opens the Replay signal page with the signal already filled in the hex field.
Click Send — if the device responds (light turns on, the door opens, etc.) the recording works.
Step 6 — Save as a device
To control the device from your phone, automations or Home Assistant you need to save the signal as a device. Go to Devices and click + Add device.
Choose type CustomMatch, give the device a name and paste in the hex signal. Save — now you can control the device just like any other RF-HUB device.
Tips
- Signal not working? Try several times — some remotes have slightly varying timing. Use the signal that repeats the most.
- Want to control on/off separately? Record the on button and the off button as two separate CustomMatch devices.
- Rolling codes (some modern garage doors, car alarms) usually cannot be recorded — they change code with every button press for security reasons. These require an original remote.
- Alarm systems and property locks are often encrypted — always check local regulations before attempting to record signals from equipment you don't own.
What happens behind the scenes
CustomMatch captures the actual pulse pattern from the remote's 433 MHz signal and stores it as an RF1 bitmap. When RF-HUB transmits the signal again, the exact same pulse pattern is recreated — the receiver notices no difference compared to the original remote.
