Hello all. * I'm fairly new to HomeKit, and while I may have a general understanding of the "Internet of Things" and "smart devices," the topic is so vast and wild that you might consider me a newcomer. Please excuse me if I ask for very obvious things or use the wrong terminology. * I'd like to check some bulbs (LEDs) with the Home app on my iPhone and Mac; this should only be possible locally, absolutely without "smart devices" being able to access the internet. I wouldn't mind adding a Raspberry Pi to the setup, * but the setup shouldn't be super complex, like switching from ZigBee components, through DCONZ, through HomeBridge, to HomeKit ... * There are two scenarios that I have them in mind, which may or may not work: 1. "Smart devices" could talk directly to my iPhone and Mac computers, for example, via Bluetooth; no Wi-Fi, no internet access, only remote control directly from the control device to the "smart device" ... 2. "Smart devices" could talk directly to a Raspberry Pi via a HomeKit receiver, and Raspberry Pi would block any internet connection and only direct HomeKit traffic locally. What I wrote above may be weird or even wrong, so I'm here to ask for advice. I also read that I could use an iPad - which I don't have, but maybe I could buy - it could serve as a HomeKit hub; I'm not sure, though, that I would need a HomeKit hub because I don't want to control my "smart devices" through internet access. Basically, I would like to use the Home app as a literal remote control, without any "smart features", simply by directly controlling my lighting via the Home app; and I certainly don't want those devices to be able to access the internet or be accessed over the internet. Thank you very much in advance.
