Ever the optimist I thought id just build a patch to drive the pump of my solar hot water, cant be that hard I have already built a patch to blink an led!
Took every second of two minutes to realize I cant see a suitable relay patch ,
I am back down to earth again looking for help please.
You should be able to just use “digital-output” node.
Thank you Gweimer…On reflection I should have worked that out.
