I am also getting this same error, attempting to use MeshWatch
https://meshtastic.discourse.group/t/meshwatch-testing-and-monitoring-tool/3923
~/meshtalk$ python3 meshwatch.py -s "test"
Traceback (most recent call last):
File "meshwatch.py", line 47, in <module>
import meshtastic
File "/usr/local/lib/python3.5/dist-packages/meshtastic/__init__.py", line 168
logging.error(f"Subclass must provide toradio: {toRadio}")

SyntaxError: invalid syntax
Thank you in advance
