As titled, I would like to be able to save a gauge (pictured below) as an image, which should then be updated/overwritten when an entity state updates, is this possible.
You should probably write a bit more about your use case.
Is it because you want to use the image outside HA or is it because you want to keep that gauge value in HA for other stuff?
Yes, the idea is to be able to use the image outside of HA, on the same network, either via the existing samba share or Esphome.
You could try this:
Thanks for the info, but I am running HA OS, so I am not able to create any containers.
I do not think you can do it within HA, so you need to get it externally.
Ok, I’ll give it a shot.
So this works ok for capturing the image, but I just realize, there really isn’t a built-in option for pulling images via a url in Esphome.
There I can not help you.
I do not really use ESPhome, but make a new post in the forum section for ESPHome.
