I'm looking for a way to identify the WiFi network to which my Raspberry Pi is connected in my program (Python) so that I can use the name of the WiFi.

From the command line


will give you the ssid of the active wlan. More config information can also be seen with


You can parse this data and use it in your program to display wlan info.

You can use the iproute2 command iw to get to which your rpi is connected:

iw dev <interface> link | grep SSID | awk '{print $2}'

iwconfig may help (man page: https://linux.die.net/man/8/iwconfig). When called with an interface name iwconfig wlan0 it should print the current information, which also includes the ESSID -- the network name.

You may need to "sanitize" the network name when you plan to use it as a hostname: hostnames should be conforming to DNS label rules, and only consist of letters, digits, and hyphens, with some additional constraints applied (so-called LDH rule). In particular, you need to remove blanks, dots, underscores, and many ASCII characters.
