Internet bandwidth is not really an issue with home control devices but video is a different thing. If you saturate your internet feed with video, TV and security cameras, nothing else will work. Also, if possible, stay local with home control devices. If you dig thru this group you will see that recommendation often and solutions. Same thing, local NVR for cameras if possible. You can still look at them remotely but they only use bandwidth when watching and your video is not stored in the cloud or in China for hackers or others to access.
