Extension board

Thanks for this great working gateway!
Is there any way to integrate an extension board like MCP23017, PCF8574 or PCA95555?
I want to connect 14 Inputs (switches) and 14 relays to my NodeMCU.
Best Regards


yes you can integrate it, you will have to develop a new ZactuatorMCP23017 component, called 2 times:

  • one for the setup
  • one at each loop
