I installed 8 HS200's and HS210' in August. Everything was good until last week all but two of them are "grayed out" in my Kasa Smart app. These are in my second home, but I have a VPN between homes, and I can see that they are connected to my Wi-Fi 2.4Ghz network, and I can ping them all too. I have knocked them all off the Wi-Fi and they all reconnected. I have restarted the AP and everything reconnects except for the same 6 Smart switches. I have cleared all the DHCP clients off of my firewall (my DHCP server), and I have even rebooted my firewall. I have reveiwed all my firewall logs and see no blocks/drops for those concerned IPs. Those 6 AP's appear in the same state on my Android phone and my iPad too. I have logged in/out on both too, with no change. I am thinking that my Kasa Smart app did get upgraded sometime since I left the second home in October. Any ideas or suggestions?
