Operate and execute commands on ESP8266 with Fauxmo library when internet connection is lost

[TATOTATOMAN]

Hello team.

I have been in this IoT for a short time and with Arduino for a few months. This project is incredible, and I have already installed it in several rooms in my house: living room, kitchen and bedrooms.
With a controller I have programmed up to 12 devices ... lights, plugs, coffee maker ..... and recently I had a problem .....
The internet connection was lost, but the Router worked .... so Alexa stopped working ¡¡¡¡

I proposed an idea that I was already using at work, which is to use the Modbus IP protocol in the ESP8266, and i'm working on it. I have crossed the Fauxmo ESP 8266 library with the ModbusIP ESP8266 library, and testing both libraries run fine.
The Beta mode idea is to cross the activation and status commands with the Modbus server variables.

I need to create the App on the mobile to be able to turn the devices on and off directly with status buttons.
As I always use fixed IP at home, the devices connect without problems, and without internet.
If someone wants to follow this path, I'm with it tb. the idea is that it always works, and without internet.
I have also made communications control to the Fauxmo program, so that it performs actions if it loses connection with the internet, as a precaution, turn on light bulbs ..... turn them off ...

I hope you like the idea.
