I looked more into my project and decided to do something a little different. I'm still going to use the esp8266 But Going to change displays I know it will cost a little more but going to use a Eink display. Also looked into the Esp8266 to sleep mode instead of powering it down which will bring the over all power consumption of the Display and esp8266 way down. So instead of 2 to 3 hours now. I can get almost a whole day out of it. The reason why I was thinking of the Eink display is because you can turn off the power of it and it will keep it's last display data in there and powering it back up for new data is fast. Still need some guidance on the Esp8266 to put it in a sleep deep sleep or Powering it down. Also i was looking into the Esp32 which has bluetooth maybe just maybe pairing it with a phone instead of a wifi But then again i will need a custom app for it. So not sure yet. What do you think?
