I’m doing a simple project with a arduino uno +Ethernet shield+relay board+dht22 sensor for a greenhouse control.
Everything looks fine. the values of dht22 on cayenne dashboard are displayed almost real time (3 seconds delay) but the buttons I use to control relays of board have a delay of minutes or even don’t change the status.
Apologies for the late reply to your post. Can you share a bit more information about your project so we can try to reproduce on our end? The sketch file you’re using, screenshots of your dashboard and the details of the button widgets would all be helpful to see if anything obvious is going on here.
