Hello When I push the button I get the following error message :

pi@raspberrypi:~/Smart-Doorbell $ python doorbell.py Starting Doorbell... Powering off HDMI Waiting for doorbell rings... Powering on HDMI with preferred settings xset: unable to open display "" [1088:1088:0611/013447.984641:ERROR:browser_main_loop.cc(584)] Failed to put Xlib into threaded mode.

(chromium-browser-v7:1088): Gtk-WARNING : 01:34:47.989: cannot open display:**

Do you know why display can't be opened?

Thanks for your help !

Regards

Ben

Do you have a physical display connected to it?

Otherwise you have to enable vnc through sudo raspi-config And uncomment the line hdmi_force_hotplug=1 in the file /boot/config.txt To force a display even if no physical display is connected to the hmdi
