Thanks for the response! It’s using the ESP32C3, but your point is the same. I was hoping to not have to open the case and mod it, but it sounds like that’s the only way. Maybe they’ll do it with the next release of the product. Knowing the battery status is something I’d think most people would want.
I knew this was a pre-release product when I bought it, so no big deal. It’s not a deal breaker and it will do what I need it to do (display some Home Assistant information). I’ll just have to remember to plug it in every now and then.
