Hi! I have a problem with i2C-scan with node-red.
My Flow just uses i2c Scan and node debug.
A SHT31 (temperature and humidity) is connected on Raspberry pi 4. It is detected with the console and the command i2cdetect -y 1. Adress 0x44.
But in node-red, i have a message: "Error: Invalid I2C bus number false"
I have tested with another card i2c but it is the same problem.
I2c is activate too.
I have tested with a program wrote in Python. (import smbus) that work very good.
In node-red (node exec ), it is the same, very good.
I don't know what is the problem. Thank you for your help please!
