Many Smart Switches and Plugs constantly resetting when blocked
I have several of these switches, as well as some smart plugs too and all exhibit the behavior I am about to describe.
I am using all these devices through Home Assistant, which I do have direct remote access to. I do not need the Kasa Remote Access at all. In order to keep Internet traffic to a minimum I have blocked *tplinkra.com and *.tplinkcloud.com in my router. However when I do this, the devices are either resetting or requesting a new DHCP address when attempting to call home and can not, thus causing them to reset something. If I disable this block, they do not exhibit this behavior at all. The Kasa app once had a switch to disable remote access, but that is apparently gone now.
So how can I either turn off their Remote Access (since the app no longer has this switch) or successfully block them in my router without them resetting every 30 minutes or so?
Thank you.
EDIT: I should mention that all these devices are on static IPs assigned from my router and all have good to great connection quality (2.4ghz only).
