This is my Eink display I made with HA and ESP home for my solar in my home. I have 2 inverters a Lux power and a Victron. Using Several all ready done projects from here I have simplified the data shown on my Eiink display.
It has a graphical Background plus overlay to display the information and is updated once every 30 min then goes into deep sleep for the rest of the time. It has a 4000 mah battery ripped from some old product so should last a very long time between charges.
It is still not completed as I what to add more features but I thought I would start a post to show you as Facebook has shown a lot of interest. I will post my full code once it is fully completed so any one can play with it.
