Shift register node

[ferpando]

Hi,
I'll start a new topic for this as I think it is a new device type.
How can I allow a node with a shift register to be controlled by the gateway node?
Is there some example sketch to deal with shift registers instead of relays?

Thanks in advance

What are you doing with the shift register?

I made an interface to control 3 somfi blinds using the remotes. I needed to control 9 buttons, so I used 9 optocouplers and 2 shift registers to get the outputs needed from an arduino pro mini.

@ferpando I guess you're using shift registers because you lack enough output pins?
You could present the 3 blinds as e.g. 3 different childId's on the node.
Each child then has 3 actuators: V_UP, V_DOWN, V_STOP
When your node receives an update for one of these values, then just update the corresponding actuator and shift out the state for all 9 optocouplers, and you're done!
No new 'shift register' type required, as I see it.

You might be right, but then again how would I learn about shift registers if I don't use them? :-)
