PyAnova-Nano

Control the Anova Nano via BLE.

This is a rough translation of dengelke/node-sous-vide.

Notes:

• The code should be considered experimental at this point.
• Presumably this library is not compatible with any other Anova model!
• The PyAnova class is not compatible with c3V6a2Vy/pyanova.

Examples

Automatic discovery

The device should be found automatically based on the service uuid it provides.

Context manager: auto connect and disconnect

import asyncio
from pyanova_nano import PyAnova

async def print_device_sensors():
    async with PyAnova() as client:
        print(await client.get_sensor_values())

asyncio.run(print_device_sensors())

No context manager

import asyncio

from pyanova_nano import PyAnova


async def get_unit():
    client = PyAnova()
    await client.connect()

    print(await client.get_timer())

    await client.disconnect()


asyncio.run(get_unit())

Manual connection

To use a custom address, first discover all relevant devices, then use PyAnova.connect(device=my_anova) with my_anova being the bleak.BLEDevice you want to connect to.

import asyncio

from bleak import BLEDevice

from pyanova_nano import PyAnova


async def print_target_temp():
    client = PyAnova()
    devices: list[BLEDevice] = await client.discover(connect=False, list_all=True)
    # Select the device to use.
    my_anova = next(iter(devices))

    print(f"Found: {my_anova.address}")

    await client.connect(device=my_anova)

    temperature = await client.get_target_temperature()
    print(temperature)
    
    await client.disconnect()


asyncio.run(print_target_temp())
