Ah I see what you have done there... Yeah makes sense.

I guess it's time for me to introduce some automated unit testing in aioesphomeapi 😅

I appreciate everything you guys do, I'm genuinely impressed by your talent and skills so I hope this doesn't sound rude or impatient.... but when can we expect this update/fix to become available? Or is there any work-around until then? Again I am honestly very grateful for what you code gods create and maintain. I'm just keen to get the esp32 cameras working again! Thanks peeps :)

When 2021.7.2 is released - depends on when the HA maintainers have time.
