Does your LAN have the bandwidth to simultaneously connect to 16 cameras? I really doubt it. That’s why it’s slow. Remove the cameras from the “Favorites” tab, and try again using the “Devices” tab.
Your internet speed doesn’t matter if you’re trying to connect from within your LAN. Your internet download speed doesn’t matter either during the connection phase; it’s your upload speed that’s important.
I’m now having to clear Storage and cache about every other day, it’s the only way the app doesnt report not having cameras (thermostats also report being offline unless I clear storage).
Really starting to think about another system, which will be painful since we’ve invested a ton in to this one.
