Devices keep going offline in homekit

I have the Hass Bridge integration installed, and devices keep going offline or are very slow to respond. If I do a reboot, everything comes back and works great for a while. They also sometimes work fine in the actual app on my iphone but are unresponsive on my watch or pull down shortcut screen on the same phone. Do I need another apple device in the house to act as a hub? Any ideas or suggestions?

You have to have a Homepod or AppleTV to act as a Homekit hub.
