Hello I wrote a scipt in python to detect distance between camera and object, i want to send the distance to an appli node red. Is it possible to convert this script into a .json file and import it into node red to get the readed data into the debug node or into the dashboard ? i've tried to exec…

You are on the right track, very good!! I thought the same idea would work and I needed to use some more nodes. I added a new path from the original 3 rules switch (just to keep the notification we already had). In there, the switch checks if the distance is < 0.5 or higher. Depending on, it sends t…

[image] wejdene.guedri: i've tried to exec the script automatically in node red but it didn"t work How exactly did you try this and what, if any, errors?

I'm pretty sure you mean convert python to JavaScript right? How much code is it? It may be a simple translation (then there would be no need to spawn python) Paste your python code in a reply - don't forget to use the code button (click it then paste python between the 3 backticks)

Forget converting to javascript. You have dependencies to external libraries specifically written in Python. Much better to run the script outside of Node-RED and communicate the result to Node-RED. As example via MQTT

No, not that way. Do it with an exec node set to spawn mode and see what you get

sorry i am a bit new to Node-red programming

Is your script working as expected if you run it in a terminal? You run it in Linux on a Raspberry pi? Anyway, I would run it in a terminal and send results (distance) to Node-RED via MQTT or http. You will have to add code in your python script for mqtt (or http) communication and if you go for mq…
