Script to change the wifi settings of a Daikin airco (tested on FTXA)

change_wifi.py

import requests

    else:
        raise Exception("Could not perform %s action: %s" % url, resp)

Inspired by daikin-update-wifi.js but in Python to avoid cross domain referencing issues in the browser.

@gjdv thanks for posting this. I couldn't get any of their terrible apps to let me set the wifi, and I only plan to use the api directly anyway.

for future people finding this, if you're using nix, the following shebang works to just grab python and the package this uses:

#! /usr/bin/env nix-shell
#! nix-shell -i python3 -p python3Packages.requests
