Please Help needed I have a Node with Sonar sensor and an digitalRead(A0) value from Node to Gateway. The value shows on Domoticz Hardware TAB, but wont show on Switches. I have stayed up all night looking for solutions without much luck. I sketch is as follows.
// Example sketch showing how to control physical relays.
// This example will remember relay state even after power failure.
