T5 2.9” V2.2 Deep Sleep Issue
cvocvo opened this issue · 4 comments
I’m using ESPHome with a T5 2.9” v2.2 epaper, and when I enter deep sleep — shortly after entering deep sleep my screen becomes weird — half white / half black display with artifacts. I will try to post a picture.
The refresh will occur in deep sleep but the display itself won’t recover.
Any ideas? Is deep sleep supported on v2.2?
T5_V2.2 supports deep sleep. If the screen is refreshed after deep sleep is set, please check what is the reason for waking up. I don't use ESPHome. I will rule out the reason for the time being. you can refresh
Check if you can sleep normally
I think you're spot on -- I played with the refresh settings a little bit and found a post with a similar issue here: esphome/issues#2334
Once I get it dialed in, I'll post some code this week or this weekend.
I think I got it mostly sorted out; battery life still isn't great but that's a known limitation of v2.2 of the 2.9" board.
Here's what I've got for code -- I solved a bunch of problems (screen reloading issue, deep sleep, sleeping the flash, button to reload, etc.) and posted code up here: https://github.com/cvocvo/esphomeprojects/blob/main/epaper29.yaml
