HomeKit how do I stop multiple apple devices acting on button presses in homekit?

[dilbert99]

I have a bunch of Ikea Tradfri Shortcut buttons and assigning a scene to them in either HomeKit or Ikea app works fine.
But if I try an program a toggle shortcut to the single press feature, it seems that my iPhone and AppleTV are both responding to the event so the lights don't change state (On->Off->On or Off->One->Off)
If I turn off homekit icloud on phone the toggle works but I can't use the homekit app - it says to turn that setting back on.
If I restart the apple tv, the toggle works while it is restarting, then goes back to duplicate events.

Am I missing something easy to fix this or has Apple really not thought about multiple apple devices responding to events?

try rebooting everything, including all home hub devices (appleTVs or homepods) as well as your router and and any network gear.

Apple devices should talk amongst themselves to prevent this from happening. Same thing should happen with "hey siri" you might notice your phone and a HomePod both light up, but all one should quickly go out as they'll agree amongst themselves which one should handle it

Have you made any weird comfiguration changes on your router? This process uses mDNS (apple calls it bonjour) and uses broadcast packets. Sometimes routers have issues with those.
Do things like airplay and the remote app work between your phone and the aTV? if not it's part of the same issue, since those also require mDNS to work.

I do have a two band router 5gHz and 2.4Ghz, just a standard setup
but Apple TV and iPhone should prevent both triggering - I can use my iPhone to control Apple TV
