HomeKit devices stopped responding

I have multiple HomeKit devices setup at home, myQ Garage opener, ecobee thermostat, Kwikset Premis deadbolt, Insteon Light Switches, hunter fan, philips hue light strips, etc. Recently about half of those devices all stopped responding through HomeKit, but only some of them. They all still respond in their corresponding apps, but they show Not Responding in HomeKit. I’ve tried resetting all the individual devices, deleting my home and restarting from scratch and I’m out of options.

If it was one device or manufacturer I’d think it was the device, but myQ, ecobee and hunter are all different manufacturers and they all stopped responding at the same time.
