Hi,

I have trouble using the GPIO in Node-Red.

As soon I select e.g. GPIO 13 as output, and deploys, the output turns on, despite that initilal lavel of pin is set to low.

The only thing attached to the GPIO in Node-Red are two injects, with the value 1 and 0.

If I press them, I can see the value under the GPIO output change value, but nothing happens on the actual output. The Output always stay on…

Hello Jesper, thank you for writing on the forums!

Could you please give me more details about the device that you are using and the Nore-Red application that you are using? Is this Node-Red from [balenaHub](https://hub.balena.io) ?

Thanks
