I have a raspberry pi zero with a relay board controlling the valves of my irrigation system. I can manually set the relays on/off through the dashboard. I’ve created scheduled events for the 6 valves, 6 times on and 6 times off. Some of the scheduled events are working fine while others are not, I can’t guess what is the problem. E.g the relay switch on in time, but it doesn’t receive the scheduled off, other relays doesn’t receive any of the scheduled events. I tried to recreate the scheduling both via web and android app.
