Hey folks!
I was wondering what’s the best way to open my garage door, when I come home (on my bicycle). Ideally The door is pretty slow so ideally I want to be able to trigger opening it about 100m/300ft away.
Bluetooth buttons have a very limited range, even if I would place a proxy (like esp32) outside I guess that wouldn’t be enough. Is there any cheap rf-based solution (similar to traditional garage openers) that is easy to integrate and not too bulky?
Low cost trial might with something like this… I have a similar 433Mhz button for a USB power switch, however I’ve not done any distance testing…

From description:
‘Transmission distance: 120-150M (open area, the sensitivity of the receiving device is minus 100dbm)’
Spendy route would be some type of LoRa or LoRaWan button:
