Hi! I am a 3 bedroom apartment, of normal size. I have an Apple TV 4K and 2 HomePod mini as a homekit hub in my house. For homekit activators, I have a lot of Aqara devices and I use a hub to connect everything to the homekit (sensor, plug, ..) and I have some external light activators, such as LED strips and lights normal. You also have a nanoleaf-driven light. For homekit devices that are not activated, I have 5 air conditioners (LG thinq), 5 Shelly 2.5 and a Xiaomi vacuum cleaner. To connect these devices to the homekit, I use a homebridge. So, if I add up every device in my house, I'm about 40. For that reason, I have a lot of unanswered issues. For devices that are not enabled (homebridge) because I connect raspberries to Ethernet, I usually have no problems. But the other devices always show the unresponsive error. For the internet connection, I have a single fibergateway router and 1 Xiaomi AC2100 that acts exactly like a bridge. Can you give me some tips to fix my unanswered issues? Should I buy a new router? And if so, can you give me some good examples? not very expensive please :) maybe 200/300 euro is my top top top. I do not have 100% confidence that, with a new router, I will solve my situation. Thank you !
