I want to share my experience with the reTerminal E1001 ePaper display and Home Assistant. My first impressions were not good. In fact, based on the limited functionality of the vendor software I was ready to return it. Then I saw a post by a Home Assistant user that encouraged me to move to ESPHome since my goal was to integrate with HA anyway. After a few bumps getting the E1001 synced with ESPHome (you need to use Chrome for the initial serial setup), I was was off and running. It has been a fun learning experience since I am not a YAML expert. My goal was to monitor my propane level, basic forecast data and have a quick at-a-glance look at things like my garage doors, pool pumps and hot water circulation. I have been able to achieve all that with a little work. I can't speak to battery life, but the build quality of this reTerminal E1001 is great. It has a metal housing, easily mounts on the wall and has buttons that can be programmed. I am very happy so far. I have my refresh set to 5 minutes, so I may end up changing that. I have it mounted beside my thermostat which is great for us. I feel that this unit is a solid value and has all the functionality you need for a home display. It has a great display for the size and connects easily to your network. I am very happy so far. Read more
