Sleeping Face for Pwnagotchi When Off

[nikhiljha]

Describe the solution you'd like
When shut down properly, draw some Zs and a face with closed eyes to indicate that the pwnagotchi is sleeping.

that's already the case https://github.com/evilsocket/pwnagotchi/blob/master/pwnagotchi/ui/view.py#L266

That is not working. Just turned off the Pwnagotchi in MANU mode via WebUI and the summary screen (Kicked/Friends/Got...) is on the display.

it appears to be a timing problem: there's a 5 seconds sleep before turning the unit off, which is enough on faster displays (waveshare v2) to display the Zzz message, but not on waveshare v1 and others.
