Non-household member controlling devices

[rov3rt]

A couple weeks ago our kitchen display began playing a particular cartoon every night around the same time. I wasn't able to figure out what was happening until a coworker mentioned the same cartoon during a conversation. Apparently, his son asks their 'kitchen display' to play this every night and it ends up playing at my house on our device with the same name. The coworker was a Google family member a couple years ago for the purposes of sharing YouTube music, and has been on our WiFi, but was removed. He does not show as a current member in my app but can still see our home devices and apparently play cartoons at our house remotely.

Is there a way to reset all access to our home?

Hi rov3rt,

Thanks for visiting the Google Nest Community. The Google Home app can see devices it can find on the same network. Kindly confirm that you are both using different Wi-Fi networks. You may also need to factory reset your Google Nest display. I suggest that you set it up in a new Home. Let me know how it goes.

Regards,
Alex

Thanks Alex. Since this original post I found their account linked under several of my Google devices, but they're no longer home members nor are they on my network. Yes, I can unlink their account by resetting the device but I thought there would be a way to unlink someone's account who's not a manager, and I have over 80 devices in my house. From his end, he only sees my devices when he goes to add a device to his home, then they all show as available to add. The problem we're having is that any devices on our two homes that have the same name get crossed up, and he ends up playing music in my house. I'll probably just slowly work my way through resetting the Google devices.
