5. Using the Blynk App
OSBee firmware supports remote access through the Blynk app. This allows you to remotely access the
controller, check its current status, and run a program. To use this feature, first install the Blynk app on
your smartphone. Then scan the OpenSprinkler Bee Blynk project QR code, available at:
https://github.com/OpenSprinkler/OSBeeWiFi-App/tree/master/Blynk
this will import the project to your Blynk app. The
full
version of the project requires paying a couple of
dollars to buy additional Blynk energy points, while the simple version of the project does not require any
additional payment to import the QR code.
Once the Blynk project is created, you can go to the project settings to obtain the cloud token. Then
paste this token at OSBee's Settings page, submit, and reboot OSBee controller. This way the firmware
will communicate with the Blynk cloud using the token, and allow the Blynk app to access the controller
remotely, even if you are not at home.
