My Tado AC controller does not work locally in HomeKit-only mode. Is this a violation of Apple’s HomeKit policies?

Cupertino, July 28, 2023

Hey guys,

Lately I’ve become so paranoid about smart home companies eventually going out of business/switching to subscription models.

So yesterday I decided to prevent my Tado AC controllers from accessing the internet and use them locally via HomeKit only.

So on my router I turned off internet access for my Tado, and for a little while everything was fine. The Tado app wasn’t working of course but I could still see the temp and control them fine via HomeKit.

Until a few hours later, when all of a sudden the devices became unreachable in HomeKit! I checked the display on the Tado unit itself and it was displaying “E04” -meaning unable to reach Tado servers.

I rebooted, and once more my Tado appeared in HomeKit and worked fine for a few hours, before again the error E04 appeared and my devices turned into paperweights.

My understanding is that a *requirement* of Apples HomeKit certification is that the devices must remain working locally in HomeKit only mode.

Is anyone else seeing this?
