This script allows us to access our Home Assistant server (HASS) through Python scripts. I posted this on GitHub and will keep it more updated there, so please check it out there.


Updated Python API Client

Go here. It is more updated.


Use the GitHub Version instead of this

from requests import get, post
import json 
class HassRestAPIClient:
    def __init__(self):
        #Change to your Home Assistant API URL (ex. http://192.168.1.100:8123/api )

        self.headers = {
            "Authorization": "Bearer BEARERTOKENGOESHERE",
            "content-type": "application/json",
        } 
    #Get information from home assistant states
    def getHassStates(self, entitysearch="", key="all", exactmatch=0):
        url = self.hassurl + "/states"
        response = get(url, headers=self.headers)

        result = []
        for entity in entities:
