I’ve been enjoying OpenGarage for two weeks during which everything worked like a charm. All of the sudden it doesn’t work anymore. I’ve intergrated OpenGarage in Domoticz and I am also using the Blynk app.
Two quick suggestions:
1. try to manually trigger relay action by clicking the button (depending on when you bought OpenGarage, the button may be on the side exposed; or it may be the inside the circuit and you can click it by using a small screw driver or something long and skinny). If the relay triggers correctly manually, that means the relay and the microcontroller is working fine.
2. Perform a factory reset: press and hold the button for more than 10 seconds, then release the button.
Also, if your firmware is not the latest, I suggest that you upgrade your firmware to the latest 1.0.6.
