Pyatv: Push Updates

[lorenzoCuevas]

Is there any way to have real time push updates from the Apple TV in python code?

[postlund]

Yes, the push updates API provides that:

Okay thanks , but do you have a complete python code on the real time push API?

[postlund]

Here's a simple one that hacked together now:

import sys
import asyncio
import pyatv
from pyatv.interface import PushListener


class MyPushListener(PushListener):
    def playstatus_update(self, updater, playstatus):
        print("Currently playing:\n", playstatus)

    def playstatus_error(self, updater, exception):
        print("Got an exception:", exception)


async def main():
    loop = asyncio.get_event_loop()

    atvs = await pyatv.scan(loop, identifier="device_id")
    if not atvs:
        print("No device found", file=sys.stderr)
        return

    atv = await pyatv.connect(atvs[0], loop)
    listener = MyPushListener()
    try:
        atv.push_updater.listener = listener
        atv.push_updater.start()

        print("Press ENTER to quit")
        await loop.run_in_executor(None, sys.stdin.readline)
    except:
        atv.close()


if __name__ == "__main__":
    asyncio.get_event_loop().run_until_complete(main())

It doesn't do credentials handling (or pairing) so you might have to do that separately. Should work directly for tvOS and older devices if home sharing is enabled however. Just replace device_id with an identifier from atvremote scan.

Okay Thanks!! 😀

If you are not interested in writing any code you can get the same output from atvremote ...push_updates as well. Or in json format from atvscript ... push_updates.

Hi again , for the push listener in Python code how could I do a if statement on the play-status of the apple TV?

[postlund]

Something like this:

class MyPushListener(PushListener):
    def playstatus_update(self, updater, playstatus):
        if playstatus.artist == "Weird Al Yankovic":
            # do something

All available fields are here. This is an async callback, so remember to not do any blocking code here.

Alright thanks
