Can you add eeprom- so that the switch state in the memory of ESP incase of blackout

[sayemahmed]

Thanks for this nice work. It helps me a lot. I was using some RF based system in my home. Now I want to replace with ESP and Amazon Echo. In my earlier system I used EEPROM to keep switch state stored in the memory. I was trying to add same codes in your code to have same functionality. But it generates WDT RESET! ESP is continuously restarting. Please help with this.

Looks good. Adding the eeprom support brings the code up another notch.!!
Have not tried it yet but will give it a shot in a few days..

Thanks!

Does it work fine without your modifications ?

If Yes, try switching to FS.h

You can always use the EspExceptionDecoder to check where is the exception coming from

It is not working with my current Node mcu. It is may be broken. I will check with a fresh Node Mcu next Saturday.

just came across this

Many thanks for this document.

The code above does not working! Please help...

Hi, I have had great success your library, and just wondered how I can add a manual switch and update alexa with the change. I have done it successfully with your single switch but finding the more library based multy switch more dificault to get my head around. Any help would be much appreciated. Regards, Cliff

hello sir
this is a best for home Automaton project .
when i load the code in my nodmcu then the massage show
Error compiling for board NodeMCU 1.0 (ESP-12E Module).
i have selected proper board ,upload speed 115200, 80mhz
what is solution
