i heard that the picamera library isn’t supported anymore and now it is used libcamera (that i am using for testing). also funny fact if i do sudo raspi-config and enable the camera, the libcamera doesn’t work anymore ahahha
I added arm_64bit=0 so it could be at 32 bit

Merci, je vais regarder tout ça ! merci encore pour l’aide

Thanks for the reply, I’ve installed MMM-GoogleAssistant and Gateway, sometimes it works, sometimes doesn’t, I modified the config file by
commented out the EXT-Selfies then added it back, everything is working fine again, weird…
