20x4 LCD i2c

[Mkorneli]

I want to use an LCD to see data without connecting to web.
I have connected sda and scl along with vcc and ground.
I have tested both 3.3v and 5v, I have tested power from pi and external.
when i do "i2cdetect -y 1" there is no address showing just the table.

so what is the secret? i have tested 2 different LCD's.

As far I know there is no trick. I2C should be enabled. You could check with raspi-config

But as i2cdetect does not show it.... than it will be a search to find out why.

I've been running this one for months now: https://www.amazon.es/-/pt/dp/B07XT7LN61

I'm using a script to query the API and output a customized layout for the display (the T.PI notification system was not flexible enough for me).
