I’ve attempted to scan the QR code on the Open Garage device with my iPhone and iPad without success. Are there instructions on how to setup Blynk manually?
I found an existing post which provided me with the details… the QR code on the device will not be read by Blynk but the QR code in the manual (PDF) does work.
The QR code on OpenSprinkler is the product QR code (it shows the product URL opengarage.io). You are right that the one in the manual is the Blynk QR code.
