I have 3 TRÅDFRI 30W drivers in my kitchen, and succeeded in pairing all of them to the same remote. However, if I pair a lamp to a 2nd remote, it stops responding to the first one. I was hoping to use 2 remotes, to get 2-way control.

From the documentation, one remote can control 10 lamp drivers, but it isn't clear to me if only one remote can drive a lamp at once. If it's possible, is there a reliable way to set it up?

I don't have a gateway. If I have a gateway, can I use IFTTT to cross connect two driver/remote pairs or subsets to keep the drivers in sync in the way that I could do with SonOff?

Yes, there is an easy, but undocumented way to do this.

  1. Factory reset the remotes (press pair 4x within 5 sec).
  2. Pair one remote to a bulb (this may not be necessary, but I did this)
  3. Hold the remotes next to each other, press both pair buttons for 10 sec. LEDs on the front come on, then flicker off.
  4. Observe both remotes control the 1st bulb.
  5. Pair one remote to a 2nd bulb.
  6. Observe both remotes control both bulbs.

From Ikea on Reddit

You can actually clone two of the same input device if you like. It's not documented but if you keep two input devices close to eachother and hold the pairing button on first one, keep holding it and at the same time hold the pairing button on the other one they will both end up in the same group. (You should get feedback from the LEDs) I'd recommend doing a factory reset on the input device you are trying to add into the group before starting the process.

(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 never found a way to get the remote inputs, only notifications about the changes in state of the lights.

I do need to go back and have another low level play with gateway, but it does seem to be a limitation.

Really simple. Just hold down both Remote pair button at the exact same time next to each bulb you want to pair with for 10s. Boom!
