I am using the tree plum pie, I want another NODE-RED. At the beginning, the GPIO is OUTPUT and then the sensing component senses something. In the other original OUTPUT becomes INPUT, the first part is set to OUTPUT at the beginning. ?

And just what is a 'tree plum pie'? and please describe your issue a little more as from my first read I have no idea what you are asking about. Give details! Providing your flow, providing a picture of your flow. Explain what type of sensor you are using.

應該是說,我想讓流程在一開始不會依靠inject來動作做一個觸動的動作,我想讓樹梅派的gpio腳位一開始就是保持vcc的狀態

It should be said that I hope this process does not rely on the injection action to initiate a touch action. I want the tree GPIO pin to maintain the VCC state at the beginning.

What platform are you using? example Rpi, macOS, Windows What release of node-red and node.js? (you can get these from the node-red startup) export your flow and attach it to a response - make sure to use the preformated text option </> Due to the language difference it is hard for me to understa…

I was able to import your flow. Let me restate what I think you want. When NR starts, you want GPIO pin 7 off. Later, you might have a sensor (or dashboard button) that should change the output state. Have an INJECT node set to run at startup to set the GPIO pin to off. Then have a switch or sens…

It should be said that the effect I want to perform is: after I press the button at the beginning, the tree plum can continue ON, and then follow the first node to do a match, generate a button at the beginning, but sense the fixed When the license plate is used, the tree plum will be OFF.

我想要將兩個結合再一起,並且去修改拍照的流程,把全部簡化成當你按下按鈕1後樹梅派會一直輸出vcc,並且按下按鈕2後將會進行拍照,如果拍照的數據結果符合你篩選的要求的時候,樹梅派將會off. I want to combine the two together, and modify the process of taking pictures, simplifying it all. When you press button 1, Shumei will always output vcc, and after pressing button 2, it will take picture…
