ESPDuino and YWrobot 4 channel relay
Dashboard through Web and Android
I can connect the ESPDuino to Cayenne with no issues. I’ve been partially successful with setting up the relay widget. I say partially as I can press the widget to turn on the relay, the relay board for relay 1 LED lights bright, I hear the click of the relay. However, when I turn off the relay through the dashbaord, the LED on the relay board doesn’t shut off, it goes dim or half brightness. The relay doesn’t click off.
The YWrobot relay board is a LOW on actuator, so when the 5v signal goes to ground, the relay actuates.
I’ve tested the relay with a normal Arduino and the relays work fine. However, when I rig it up to cayenne with the ESP, I get this odd result.
