Just thought id leave this here as i had some trouble with it: If you are trying to use node-red-node-pi-gpiod and you are getting an error that the connection on localhost was refused although the daemon is running try changing localhost to ::1. This is the way to loopback to localhost via ipv6 w…

That is odd, I would have thought both would work. Does 127.0.0.1 work?

OK. I am not going to say I fully understand, as I don't.

The pigpiod node tries to connect to the pigpio daemon that can be installed and run on raspberries. For some things like pmw it’s a lot more efficient to use this daemon instead of the normal gpio nodes to control them directly. This daemon has as one of its start arguments the option to bind it t…
