Code

Code for Controlling the relay over Cloud

Python
WARNING:- You may need to buy Bolt Cloud Pro Plan for the project as it hits Cloud number of times, or consider adding sleep function to delay cloud hits.

Also I'm using Active Low Relay, change your code according to the type of relay you have.
Set "HIGH" if result["cfl"] > "1" else "LOW"
and similarly other constraints.

Also here cfl and fan are the two constraints that I declared in my firebase database add or remove the parameters according to your requirements.
from boltiot import Bolt
from firebase import firebase

mybolt = Bolt("Your API KEY", "Your Device ID")
firebase = firebase.FirebaseApplication("https://yourdatabasename.firebaseio.com", None)

prevcfl = 0
prevfan = 0


while True:
    result = firebase.get("your bucket name", "")
    print(result["cfl"])
    if(type("") == type(prevcfl)):
        mybolt.digitalWrite(0, "HIGH" if result["cfl"] > "0" else "LOW")
        mybolt.digitalWrite(1, "HIGH" if result["fan"] > "0" else "LOW")
        prevcfl = result["cfl"]
        prevfan = result["fan"]
    if(result["cfl"] != prevcfl):
        mybolt.digitalWrite(0, "HIGH" if result["cfl"] > "0" else "LOW")
        prevcfl = result["cfl"]
    if(result["fan"] != prevfan):
        mybolt.digitalWrite(1, "HIGH" if result["fan"] > "0" else "LOW")
        prevfan = result["fan"]
