Timer and Blynk Hardware provisioning

Issues and Errors
1

Timer isnt working in the blynk Provisioning.

I have tested the hardware and timer widget with a regular project, connecting the hardware directly to the project and it works. When I use the NodeMCU provisioning, everything is working, Led, Relay, relay + a button, but when I include the timer, doesnt work.

I have also read the virtual pin of the timer, and voila! I found what is happening, or at least I think I found it! :slight_smile:

When I check the API URL, the value is “1” or “0”, but if I change it from the app, nothing happens. Then I went back to some old projects and I realize that the API was reading the project timer and not the app timer, but Relay and NodeMCU is linked to the App timer and not the project timer as in original projects with Blynk.

So I guess, Timer is not working in Blynk Provisioning. The code is as simple as the one in the regular projects, but this one is not working at all.

Any ideas? Here down below the details:

  1. Search forum for similar topics: I searched a lot but nothing appeared.
  2. Add details :
    • Hardware model: NodeMCU v3 ESP8266 Lolin1 § communication type: WIFI ESP8266
    • Smartphone OS: Android + version 9 (Samsung Galaxy S8)
    • Blynk server
    • Blynk Library version: 0.6.1
