Binary_sensor on/off indicator on offline node

ESPHome
1

Hello.

First, sorry for my bad english :slight_smile:

I'm using ESPHome with web_server v3 on an offline ESP32 (AP mode only) and i can't see the on/off indicator for the binary sensor when connecting with a no internet device (like my smartphone). Working good with a internet connected computer.

Someone can help me, please ?

Thank you.

After some further research, it would appear that the problem is known: 'local' option does not work with http server v3, graphics still loaded from external site · Issue #6642 · esphome/issues · GitHub
