IKEA Trådfri & HomeKit, other HomeKit comparable systems.
Does a person need to buy the Ikea Trådfri gateway to use Ikea bulbs or outlets with the Apple HomeKit system?
Or, can you just buy Ikea bulbs & outlets or switches, and connect them with HomeKit?
I find it confusing, when, for example, I bought at GE air conditioner, and needed to download a GE app, then I opened it with HomeKit, and HomeKit informed me I had to download some other GE app on my phone to update the software on my air conditioner. That worked, but do I still need to keep two GE apps on my phone? Getting help is not so clear on this. As soon as you move from one company to the other, you usually are told, 'check with the other company.'
