Yes, there is an easy, but undocumented way to do this.
Factory reset the remotes (press pair 4x within 5 sec).
Pair one remote to a bulb (this may not be necessary, but I did this)
Hold the remotes next to each other, press both pair buttons for 10 sec. LEDs on the front come on, then flicker off.
Observe both remotes control the 1st bulb.
Pair one remote ...
The first issue with your proposed setup is that your Mac can't communicate with any HomeKit devices. It's unclear why this is the case, and you would have thought that one Apple platform should be able to talk to the other. But, unfortunately, they can't.
Luckily, the Trådfri hub does support remote control from your Mac (or any device, really). You can ...
It's unclear from your post which link key you are using. If it is the standard ZigBeeAlliance09 TC link key referenced in the post, then it will likely not work since Tradfri uses ZigBee Light Link. ZLL uses a different link key to the ZigBee Home Automation / ZigBee 3.0 well known shared key and The ZLL master key is not publicly available (although there ...
The IKEA TRÅDFRI gateway doesn't offer Wi-Fi connectivity on its own. To access your TRÅDFRI gateway through Wi-Fi, you must first plug it into your Wifi network with the LAN cable provided.
This information is not (yet) provided in the printed TRÅDFRI gateway manual, but it shows up when performing initial setup through the TRÅDFRI app.
(This is from observation, not documented fact)
I don't believe this is possible, even with a gateway.
In the gateway setup, groups are defined by the remote/dimmer/pir. You pair the controller with the gateway then use it to add lights, there is no way to add a second controller to a group.
Also when I did the work to reverse engineer CoAP protocol I ...
Assuming the driver behaves like any other bulb the trick is to pair the dimmer with the Tradfri Gateway then use the dimmer to add the driver to the gateway.
From the Gateway documentation
ADDING DEVICES TO YOUR GATEWAY
You cannot add light sources directly to your gateway. A TRÅDFRI steering device is needed to add
The phone app should guide you ...
The Tradfri gateway is not a WPS certified or a wi-fi certified product, it's a wired product to your router.
The app is only usable when connected to your router's wifi. If you want to control devices outside of the wifi network, you must enaled Google Assistant or Amazon Alexa. Tradfri bulbs and remotes are also compatible Philips Hue or Smartthings, you ...
You can create multi speaker groups with Google Assistant devices (Google Home, Google Nest mini, Google Nest Hub...) and you can "cast" the audio to these groups directly from your phone.
The app you use to play the audio needs to support casting, but nearly all do since the actual support is provided by the Google Play Services library and it's just a ...
The Mozilla IoT wiki made note of this exact problem.
If you have problems resetting the plain white (non-colour) IKEA bulb, try making the "ons" very brief (less than a second) and the "offs" longer
This solution worked well for me, and I was able to reset them without much trouble after trying it.
A "room" in Ikea speak is the combination of a control device* and one or more bulbs.
If you have 2 distinct set of bulbs+controllers those are separate "rooms"
*You can pair multiple controllers to the same set of bulbs
You could use the zigbee2mqtt project. It supports a ton of zigbee devices including your remote and socket, as far as I can tell.
However, you need an CC2531 USB Stick, which acts as zigbee gateway, plugged into a computer (a Raspberry Pi will do).
Control of the devices is via MQTT as the name implies.
Nice side-effect: now you can add any kind of ...
You can use the dimmer to added a driver to the app.
Follow the steps in the app with the dimmer already added before doing this:
Take the dimmer over to driver and hold the pairing button down for about 10seconds on the dimmer right next to the driver (driver must be powered on). The red led will like up, do not let go of the pairing button until the red ...
I performed a factory reset on the gateway. I noticed that one wireless dimmer seems to be defective (firmware update stalls and battery is depleted) so I tried joining the driver through the other non-defective wireless dimmer and that effectively did the job.
