can't retrieve location reports from 'third party Airtag'

[snomile]

I tested real_airtag.py with some 'Airtag compatible' AIYATO tag(link is here), and can't retrieve any location reports. The http response code is 200, but no content.

The tag is compatible with Findmy network, I can locate the tag via FindMy app, all functions go well and smooth, no difference compared to Airtag.

I also tested other devices such as AirPods Pro and MacBook Pro, they all work fine with real_airtag.py.

This is part of plist of AIYATO tag, please tell me what information should I provide more, thanks!

Interesting... it should just work, as 3rd party tags are functionally compatible with the official ones, and this library does not make a distinction between them.

One thing to note though, when you check the FindMy app, was the reported position near one of your Apple devices? Devices will record at which location they last connected to the tag, and will show that location instead if is more recent than whatever the network reports. They will also not be "findable" by other people's devices as long as they are in your proximity. This library only fetches locations reported by the actual FindMy network, so it will inherently generate fewer reports than what you will see on your devices.

thanks for you reply. I've tested two tags, one is near my iPad while another tag is several hundreds meters away, they all shown in FindMy app and both no luck on retrieving location reports. then I unpair one tag from my iCloud account, pair with another iCloud account, decode the plist from new account, suddenly I can retrieve location reports! I must say it's very strange, and hope these information is helpful.

That is very strange indeed, maybe the FindMy app on mac still had the wrong information cached?

As I understand it everything works now, correct? If so I will close this issue.

tried to decode plist from different Macs, the plists are all the same, so I don't think the plist is staled. another wired thing here, after changing the "hours" from 7 24 to 1, I suspect the server will give me reports of last 12 hours(according to the code, there're 24 hours margin), but instead there're only part of it. If I restore the hours from 1 to 724, I can get the missing reports which almost one report per minute. Does that suggest there's something wrong with the public key generation?

        """See `AsyncAppleAccount.fetch_last_reports`."""
        coro = self._asyncacc.fetch_last_reports(keys, hours)
        return self._evt_loop.run_until_complete(coro)

The hours attribute is known to be "broken"; Apple's server does not seem to honor it. I'd recommend to just filter out the reports you don't need yourself. Changing that attribute simply asks Apple to send more or less reports, but the key generation remains unchanged.

OK，thanks.
