I have a Shelly Plus 1 connected and working, if an input is detected the Relay o/p operates after a set time (eg 30 seconds).
But if the input signal is removed, I do not want the Relay to operate. At present the Relay operates no matter how short the input signal.
Is it possible to arrange for the Relay NOT TO OPERATE if the I/P signal is removed.
Thanks in advance, this is my first experience with Shelly Plus 1
