I2C io interface
#28
How did you check the output? All pins of the 8574 should be high when SIP is at rest.
Usually relay boards should be pulled down to activate. not sure which board you have.

I haven't tried an "active high" board but will do that one of these days although the plugin is not in control of that, SIP itself does.

Sorry to see the 8575 isn't working. Do you see the boards with the i2c scanner?
