That wouldn’t help, in fact when some devices have different signal range it would cause unexpected and undesired effects.
Let’s say we have
- device A with increased transmission power
and - device B with default TP on 30m distance
Device A can reach device B easily: for device B to send a confirmation signal, or to send an event, or to relay an other device’s message as hop, it never can reach the device A.
The system won’t work as expected.
