Homekit accessories constantly going offline?

I have had these homekit accessories for about a year with little to no issues, stable, occasional drops but nothing that couldn’t be explained away. Recently, my entire home, each non-apple accessory cannot and will not stay “online”. Nothing has changed in the network, all devices have power and are connected to the wireless network and are fully reachable through a ping. Accessories that have a companion app, such as myQ, work perfectly fine in their app, but homekit refuses to believe the accessory is connected. I have recycled power, to each accessory and the primary (Apple TV 4K), and secondary hub (Apple TV 4K). Firmware is up to date from what I can tell. HSV devices I am completely clueless about because there’s no companion app, so troubleshooting is nearly impossible. I assume my only option is to completely reset every accessory in my house? I’m not sure what’s going on, I really feel like i’ve tried everything. And apparently there is no actual support forum for Homekit? so i’m posting this in the wrong place… Is homekit end of life? i feel like there is no support forums and how little development is being put into homekit it seems very end of life, should i be looking for a new home solution? probably.
