I have a raspberry pi 3 B+ and the blynk app works great with it, 1 problem, it dosnt see all the gpio pins on the app, how do i fix that?

Some additional information would be useful…

  1. Add details :
    • Hardware model + communication type. For example: Arduino UNO with Ethernet Shield
    • Smartphone OS (iOS or Android) + version
    • Blynk server or local server
    • Blynk Library version
    • Add your sketch code. :point_up:Code should be formatted as example below.

Simply paste your code between ``` If you don’t format your code, your topic can be deleted by moderators.

```cpp

void loop()

```

Raspberry pi 3 B+ with enthernet
samsung s9 with the blynk app (not blynk lot)
android v10
im not shure if its a local or blynk server, when booting on the pi its “[1] Connecting to blynk-cloud.com:80” but on my phone, to connect to its account i use my IP address and username and password.
I dont have a code, i just use the normal sudo ./blynk --token=…

it there a way to have blynk virtual pins trigger gpio pins on raspberry pi? if I can do that, thats also fine, kinda annoying the app cant see all my gpios but what can you do lol

You can try Node-RED with blynk plugin

and any plugin like this for example

For Blynk to work on your Pi you need to have installed a library. The options for the Pi are Python, NodeJS or C++ with WiringPi. However, WiringPi was deprecated in 2019 so that’s not really an option.

You also need some code (a sketch, or script) which tells the device what to do when it receives a command from the Blynk server/app, and what data to send back to the server/app.

Alternatively, you can install Node-Red and the blynk-ws contrib as described above.
