I'm looking at replacing my current indoor garage opener. I have a Sonoff CH4Pro Rev4 complete with the Wi-Fi. The unit wil open both of the doors, but developed a phantom door open. Meaning the doors would open when no one was at home or in the middle of hte nght. The cure for this is to unmount the device from the wall and open it up and then press the reset button. It does fix it, but then the phantom returns. PIA to take off the wall, open it up and press the reset button. this is a known issue with the device.
my question is, can the Arduino Giga complete with the Giga Display shield perform the same function? Thought the display shield would be a nice touch, with 2 buttons on it. The progamming will be a bit of a challenge for me as well.
Now, my garage door openers are aoubt 25 years old and use a dip switch to set car wireless remote to the main unit. Inside the house, there are 2 set of wires that come from each door. Had a simple button to open and close originally.
I'm sure there wil be lots of questions and I can add photographs if that will help.
Thanks in advance,
Scott

@powderjockey The phantom is a neighbour and they have a modern system with rolling codes, it changes every activation, you have old dip switch tech. I am not sure if the tech is WiFi or something in the ISM band. If it's not wifi, the GIGA will be useless.

@zander Don't really understand the rolling code thing, but does this have to do with the 433 mhz band? All in the area are 433 mhz door openers.
Any other suggestions that might replace the Sonoff?

@powderjockey Rolling code means the key changes each use, this prevents the ancient practice of thieves hanging about near some garages and 'listening' for the code that used to be fixed. Now they can't use the code they 'hear' since it has already been replaced. I didn't know those units were 433mhz. I know that as LORA, Bill did a video/article on LORA a little while ago and I have a few of those radios.
That means you can get a lot of help from Bill's video and article. I STRONGLY recommend you read the article as the common board is NOT breadboard or header pin friendly.

Arduino Giga has Wi-Fi capabilities. It can be used to control the doors remotely, similar to your Sonoff device. A Giga Display Shield can add a display to show the status of the garage doors (open/closed) and buttons to control them manually. You’ll need relays to interface the Arduino with the garage door opener. The relays will be used to simulate the button presses. Arduino and the relays should be powered correctly. The Arduino will need a stable 5V or 3.3V power supply, depending on your setup.
