Did you buy your waveshare 2.1 hat recently ?

If so your likely hitting the issue I came across which is its actually a v3 rather than a v2 hat.

There is already a code fix just not yet in a release.

https://github.com/evilsocket/pwnagotchi/pull/1069

I manually made the changes to the 6 files relative to the copy in: /usr/local/lib/python3.7/dist-packages/pwnagotchi on the pi.

Updated my config to waveshare_3 and it now works.

File "/usr/local/lib/python3.7/dist-packages/pwnagotchi/plugins/default/ups_lite.py", line 83, in on_ui_update if capacity <= self.options['shutdown']: You have not mentioned that UPS (Pi Sugar or something) is connected. If none present and ups is switched on in config file (main.plugins.ups_lite.enabled = true) than pwnagotchi won't start.
