Hello, I would like to ask what is the recording range of sub-ghz in meters? Why do I always have to be very close to get a signal?

That’s going to depend on the device sending the signal to a large extent. It will also depend on frequency, other nearby signals, and many other factors. I just tested mine and I was able to receive a 433mhz signal over 12 meters away consistently. I didn’t test any farther then that but I’m sure it can go farther.
Receiving the car’s remote control signal must also be particularly close
The antenna of the Flipper Zero is small.
When the Vet is reading the chip of my second dog, he takes his reader, place it somewhere near the left neck and got a beep.
When I try this with the Flipper, I need to press it a few cm below the left ear, vertical and got a beep 3 if 5 times.
So I take my first dog, I know exactly where it is, better to reach above the left shoulder and beeps 9of 10 times, every scan is a success at the second try.
This is RFID, not SubGHz, but the point is the same. Two exact same tasks (read chip from dog), one time good, one time a pain in the ***.
But who to blame? The Flipper? The Implant manufactory? And what is the expected outcome? It still will be hard at some devices.
Maybe the oscillator in your car keyfob is not very clear. The tolerance is foot enough to be compensated by the receiver in your car, but the Flipper receiver has issues with the timing in some distance.
If you tell now ‘this is for every car key’, I’ll answer: Maybe the protocol is faulty implemented.
Than you can reply: this happens with every key: There are more signals than car keys. You should experiment only with your own.
I’ve enjoyed our conversation much, but I don’t see any results.
