Hi.

I have a question.

In my system i have a MCP23017 connected to nodeMCU for lights control.

i have set on it 8 input and 8 output.

The output depending from the inputs.
The system works well but in the reboot MCP bring to 0 all the outputs..

Is there a way to read the input on boot of nodeMCU and Then command the outputs? like a rule in ESPeasy
