problem Rasperra 3B + Volumio 2.457 + hd44780 + I2c display

Hello ,

I’ve been playing for a couple of days with Rasperra 3B + Volumio 2.457 + hd44780 + I2c display

The problem is that Plugins do not work

I installed volumio-hd44780-plugin-master.zip and Raspdac0.0.3.zip

in http: //volumio.local/plugin-manager, I am not active, no settings in the settings

sudo i2cdetect -y 1 is port 27 visible

does anyone have the same problem? or any solution to this situation?

greetings
