Hi everyone,
I have created project to contrl several relays and to read several sensor signals.
The already available datastreams work fine but I needed several other switch buttons, gauges etc.
For this I have paid to the Plus plan and added additional datastreams in the used template. Basically I have copied and pasted the settings from the existing integer virtual pins, but changed the names accordingly.
Nevertheless I cannot use these additional datastreams meaning, when I press a button on the mobile phone app it is not recognized by the arduino and when I want to send data from the arduino to the phone app it does not arrive there.
• Hardware: Arduino UNO WiFi Rev2 + Arduino Relay Shield
• Smartphone OS: iOS XS
• Blynk app version 1.28
• Blynk Library version: 1.2.0
• Blynk WiFiNINA_WM version: 1.1.2
IMPORTANT: I believe that the problem can be related to the template which I use. The quicktemplate and the one created by myself.
Here is my code:
