Garage Opener with LoRa Transmitter possible?

Hardware

Hey there,

i will move in my new flat next week. And of course i want to integrate everything in Home Assistant. Including my Garage.
Its a komplex of buildings and the garage entrance is far away. So i would like to integrate it in my HA. But how?
Bluetooth and Wifi are not possible in that distance and walls the signal needs to go through. The distance is arround 200m and the signal needs to go through the whole building in the end.

So searched a lot and found solutions with a Sonoff SV connected to the original remote.
There is a way to work with a shelly one. But its a shared ownership in the garage.

So my idea is to copy the remote controll i get. Analyse the signal with “universal Radio hacker” and rebuild it with arduino and sent it via a USB to LoRa Data Transfer Module, Based On SX1262.

i just connect that to the intel nuc via USB where my homeassitant is running on. And than the idea is to send the signal that strong out of the flat that the door 200m far away through a building will open.
Is that possible ?

Thats the idea. But i don´t know if this could work.
The other idea would be to use a Arduino board uno for example and connect it with a LoRa Transceiver or transmitter to anylse and to send the signal strong enough and use the arduino integration in HA

Would that work? I am a beginner. Maybe some of the questions are naiv. And the ways are not really well thought out but i am curious and i would love to get some help.
im a nativ german speaker. If some german guy wants to reply it helps maybe with the language barrier.

Hope for help curious about the community and my first trial here.

For the garage door side you could look into the following:

Here is a project around the alarm in a garage but should be able to be adapted to include the remote"

Thank you. I found that video on my researches too. But it is to complex i guess. What i want is just to send to copy the the remote controll and send the signal THAT strong that i can open it from my flat.

And in this example he build a pretty complex solution with connection in the other direction. So a sensor from the garage sends to the HA system.

But what i need is something that just send strong enough. And that could work pretty easy if possible i guess. I just search for the right hardware and a way to integreate it.

I guess the LoRa Systems could handle that. But i don´t know how to integrate them.

Unfortunately there is not much out there overall that is more plug and play when it comes to LoRa as yet.

It’s why I linked that git with the MQTT option since all they have there is a remote being tapped into through a board to control it that way.

Thank you. I am a beginner. Maybe i can´t addap the steps correctly for my project cause there is not the full knowleadge on my side.

Who would you exactly just send the signal? How could that work?

Till now i just could communicate with chatgpd in that topic and it says it could work with that

Waveshare USB Lora stick.

Would it work with that one ? And how could it be integrated?
Cause i just need to send.
The receiver is already existing. I guess it is out of the 80´s and work with a normal remote controll.

and could i send the signal strong enough with that stick to open the garage door as i would use the remote controller ?
