Python home assistant examples

I'll provide you with some Python examples for Home Assistant (HA).

1. Basic Example: A Simple Light Switch

Create a new YAML file, e.g., light.yaml, and add the following:

switch:

platform: python

module: my_light_switch

Then, create a new Python file, e.g., my_light_switch.py, with this code:

import asyncio
async def turn_on():
return True
async def turn_off():
return False
def setup(hass, config):
hass.services.register('light', 'turn_on', turn_on)
hass.services.register('light', 'turn_off', turn_off)
class MyLightSwitch:
def init(self):
pass
def turn_on(self):
asyncio.run(turn_on())
def turn_off(self):
asyncio.run(turn_off())

2. Example: A Smart Lock with a Fingerprint Reader

Create a new YAML file, e.g., lock.yaml, and add the following:

lock:

platform: python

module: my_lock

Then, create a new Python file, e.g., my_lock.py, with this code:

import asyncio
class MyLock:
def init(self):
pass
async def lock(self):
Simulate the locking action
await asyncio.sleep(1)
return True
async def unlock(self):
Simulate the unlocking action
await asyncio.sleep(1)
return True
def setup(hass, config):
hass.services.register('lock', 'lock', MyLock().lock)
hass.services.register('lock', 'unlock', MyLock().unlock)

3. Example: A Thermostat with a Temperature Sensor

Create a new YAML file, e.g., thermostat.yaml, and add the following:

thermostat:

platform: python

module: my_thermostat

Then, create a new Python file, e.g., my_thermostat.py, with this code:

import asyncio
class MyThermostat:
def init(self):
pass
async def set_temperature(self, temperature):
Simulate the setting of the thermostat temperature
await asyncio.sleep(1)
return True
def setup(hass, config):
hass.services.register('thermostat', 'set_temperature', MyThermostat().set_temperature)

4. Example: A Security Camera with Motion Detection

Create a new YAML file, e.g., camera.yaml, and add the following:

camera:

platform: python

module: my_camera

Then, create a new Python file, e.g., my_camera.py, with this code:

import asyncio
class MyCamera:
def init(self):
pass
async def capture_photo(self):
Simulate the taking of a photo
await asyncio.sleep(1)
return True
def setup(hass, config):
hass.services.register('camera', 'capture_photo', MyCamera().capture_photo)

In these examples, you would replace the simulated actions with real code for interacting with your home automation devices.

How to install Python library in Home Assistant?

I'm happy to help you with that! Installing a Python library in Home Assistant can be done through several methods, and I'll outline them below.

Method 1: Using the Home Assistant Store

Home Assistant has a built-in store where you can find and install popular Python libraries for automation. Here's how:

The library will be installed and added to your Home Assistant configuration.

Method 2: Using pip

You can also install Python libraries using the pip package manager directly from Home Assistant's configuration directory. Here's how:

For example:

pip install pyscript

Method 3: Using a requirements file

If you're using a Python script or integration in Home Assistant, you can specify dependencies in a requirements.txt file. This file is used by Home Assistant to install required libraries when setting up your instance. Here's how:

pyscript

Remember to always check the library's documentation for specific installation instructions and any potential dependencies or requirements.

I hope this helps! Let me know if you have any further questions.
