Easiest way to show values via web

Hi, I need to have a quick and easy solution to show GPIO values (digital and analog) on a simple web interface - remotely.

I have an ESP8266 which is connected to the internet using a smartphone as hotspot 24/7 (nothing else is possible). I also have an own server with Webserver and docker.

What’s the easiest way to get GPIO values accessible through the web?

I need some states of GPIO pins and one analog value (which is optional). It should read and post these values on change.

I was reading something about InfluxDB and Grafana but it’s a steep learning curve for me and a bit too much for my needs.

I was expecting to have a simple html with a table on it where the GPIO values are shown.

It would be cool if you guys have easy ideas for it. I’m not a completely beginner but far from being a professional. I’m able to understand most of the codes I read online.
