Introduction
Create offline timelapse photographer power by solar power using Raspberry Pi. When the Raspi connects to the internet, it will start transferring the images to a net storage. The uploaded photos will be then shown on a separate web page. Also, by triggering GPIO pins, Raspberry Pi will send a separate photo directly to the net storage. These photos are used to adjust the position and alignment of the camera.
Connect to internet
My Raspberry Pi 4 uses WPA to store wifi and ethernet data at /etc/wpa_supplicant/XXXX.conf file. It includes
country=ee
update_config=1
network={
ssid="My Phone"
psk="very secret passphrase"
}
The internet connection can be shut down using sudo ip link set wlan0 down which mimics the procedure that my hotspot is not nearby. ip a or using ping you can verify that there is no internet connection. When connecting to back to internet [up] (or setting the hotspot on) everything should work. However, for some reason my Raspi did not connect to the internet, but by using sudo dhcpcd it works.
