@jzamero : sorry for not replying. 8 relays is fine with a pcf8574 board, but you get into trouble also to connect the 8 switches. This is no supported as fas I can see today. therefore I would not recommend to go with 4 shutter on ONE esp

Thank you I saw in the wiki that you can connect with pcf8584 up to 64 io If so why can’t I connect 8+8 relays and switches

stefanbode commented 5 years ago

The problem is that my extension of the PCF still not support switches. I want to do this but delayed ti all the time
