I need some assistance on how to buffer a message if there's no network or get a pulled state of a Raspberry GPI.
I have a state on a GPI, sending it via udp to another system. But as soon as the network connection is disconnected, of course this message will be lost. So I'm looking for a way of buffering it, until I know, the other device can receive that message.
The alternative would be a way to get the RPI GPI state by pulling the state rather then pushing through the RPI GPI node, if there's any way to do that.
Thanks for you help, have a good day!
