Hello,
I programmed an irrigation system myself 4 years ago. With a very simple button in the WebUI. That worked too.
Not as stylish and extensive as OpenSprinkler but it worked. Now I wanted to switch and immediately after the installation, when I confirmed that I wanted to have open sprinklers in autostart, 2 of 6 relays started switching every half a second.
Where do I start looking? I put my old SD card back in. that doesn't happen.
What other information is needed? Which GPIOs do I use?
Sorry, I'm a little at a loss right now
I hope someone dares to tackle the problem
Thanks
