Control the Anova Nano via BLE.
This is a rough translation of dengelke/node-sous-vide.
- 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.
pip install pyanova-nano
The device should be found automatically based on the service uuid it provides.
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())
import asyncio
from pyanova_nano import PyAnova
async def get_timer():
client = PyAnova()
await client.connect()
print(await client.get_timer())
await client.disconnect()
asyncio.run(get_timer())
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())
The Anova Nano deos not update the client on it's own. We have to ask it for updates. This library allows you to poll the device for updates and subscribe to be notified.
import asyncio
from pyanova_nano import PyAnova
async def main():
async with PyAnova() as client:
def handle_update():
print(client.last_status)
client.set_poll_interval(4)
client.subscribe(handle_update)
client.start_poll()
# We should get 3 updates in 10 seconds before stopping the polling.
await asyncio.sleep(10)
await client.stop_poll()
asyncio.run(main())
- The Anova Nano can only maintain a connection to a single client. Ensure that nothing else is connected to your Anova Nano.
- Try turning the device off and on by holding the start/stop button.
