I have a problem that started recently with my setup, as follows and I am trying to find a cause / solution. I have IKEA Tradfri lights and sockets that worked pretty well. I've always controlled them with the Home or Siri app on my phone. Recently, the accessories look like "Update" in the app and finally show a status after about 5 minutes. When you control them as above, it may take 5 minutes to respond to the command. However, I use an Apple TV as my home hub, and if I use my Siri ATV, the accessories respond instantly. So, I think the problem is the communication between the Home app and the Home Hub. In trying to fix it, we tried the following: - Restart all devices, hubs and accessories, router, etc. - Hubbing the ATV and using an iPad as a Home Hub. - Factory reset of the ikea gateway. - Remove everything from HomeKit and read. In removing everything from HomeKit and adding it again, the responsiveness returned for a few hours, but eventually returned to the above state. For information, the following is setup: -Google Wi-Fi (wired to network switch) -ATV 4K as Home Hub (wired to network switch) - Tradfri Gateway (wired to network switch) - iPhone (connected to Wi-Fi ) NOTE: To eliminate mesh network issues, I disconnected the satellite network to use only the main Wi-Fi hub. Has anyone experienced this before, or do you have any ideas on how to fix or troubleshoot further problems?
