Web interfaces

Is your feature request related to a problem? Please describe
Is there any possibility to grant a www interface? It's about: I have a device in the garden and I want to control the switch off via the arduino according to the state of the batteries, i.e. when it has a 25V battery, the switch will turn on, as soon as it has a 27V battery, the switch will turn off. It would be enough if the device had a web interface where I could load the current values. Now I have it through HA and tuya, but what if the internet turns off, it wouldn't work.

Please Take a Look at the wiki for possible ways to Set or get data
Where exactly? I guess I'm still overlooking it :)
Yes, I know where the wiki is, but where and how to set it up so that I can read the data from the second device on the local network, when the mqtt server is elsewhere and when the internet goes down, I can't access it. I really need to read the values even when the internet is not working
When Internet Not working but Network avaible you can get data over esp-ip/livejson, it Delivery all Data as json String.
Unfortunaly is See its Not well documented in this project
And how can this data be obtained?
Send from another ESP or Something Network connected a http request to this Adress.
I don't understand this... could I ask for an explanation?? what will the address look like to which I will connect from the second device to get the raw data in json??
The Adresse ist http://esp-ip/livejson
For Test Just call this Adress in your Browser, you will get the livejson String.
So with any other connected device you need to build a http request.
