Python Asyncio IoT

Please note: read the guideline before starting.

You're given a skeleton of the IoT service taken from the internet. As you have noticed — it's fully synchronous and has blocking operations (for example, sleep). This task aims to make the program work faster (using asyncio) without breaking its logic.

For easier asynchronous setup, please follow these steps:

1. Make your code use asyncio - connect/disconnect/send_message must be async functions (just the async/await interface). Is the code working faster? If the answer is no - then proceed.

2. Try to gather registering devices — that should be easy. Devices may be registered simultaneously. And when you run the code — wow, it works faster (at least should). That's because each device doesn't need to wait for the previous to register.

3. After that, gather running programs (in service.py) - here the code also may be easy. And if you run it — wow, it works so fast, asyncio is powerful! But look at the logic — we've broken it: we may start playing music on Speaker before it was turned on, same with flushing and cleaning Smart Toilet. So, despite it working fast, it works incorrectly.

4. And finally, your task is to fix these logical problems. As you already have understood, some of these operations may be performed in "parallel", and some of them must still run in a sequence (flush -> clean). So, you may use these helper functions:

   from typing import Any, Awaitable
   
   
   async def run_sequence(*functions: Awaitable[Any]) -> None:
       for function in functions:
           await function
   
   
   async def run_parallel(*functions: Awaitable[Any]) -> None:
       await asyncio.gather(*functions)

   You have to change the wake_up_program and sleep_program blocks and their run — to the combination of the run_sequence and run_parallel sending messages to the service to make it more logical. Please do that separately, firstly for wake_up, then for sleep.

   Hint: Remove variables wake_up_program and sleep_program and run the programs block. Instead, you should combine run_sequence and run_parallel with the same commands from wake_up_program and sleep_program. The parallel running is always preferred, because it is faster, but logical order should be taken into account (for ex: switch on -> play; flush -> clean). After that, your code will work a bit longer (still faster than at the beginning), but at least it works correctly now.
