Tempature info on home assistant

i have a few esp01s setup as web servers around the house that show room temp from an attached sensor. how can i add them to HA without having to reflash and all that? this is what they show at their respective IPs


If you don’t want to make any changes to them, you could try a scrape sensor to read and parse the web page they provide.

i tried a few things but gave up and just used esphome and reflashed them lol, so glad i did.
