Apple TV home hub can't connect

Everything was working with a number of meross devices connected via home in my iPhone app. Then I got the message on my phone that the home hub can't connect. I removed the homekit hub on the appleTV and created a new one. Still nothing worked. I removed one device and reset it and it said it was already in use in another home. I then deleted the home in the iPhone and created a new home. I still can't get the device to add to the new home. any suggestions?
