Don't know how to use pcf8574 cluster node

General
1

In a python script i would write this:
bus.write_byte(0x20, 0x02)
to send a command to a pin of the expansion board(PCF8574).

How do you have to fill out the cluster node and the cluster configure to do the same?

2

did you read the description on the nodes page?

3

of course but I don't understand them

So what have you defined in the node?

EDIT: you may want to look at the issues on the node's GitHub page, there seems to be some problems with it.
