Ensure that your Eufy camera model is compatible with Google Assistant. Not all cameras are compatible, and compatibility Storiesdown may vary between different Eufy camera models. To stream your camera feed to a Google display, you usually need to connect the camera to your Google Assistant account. Follow the setup instructions provided by Eufy and Google to link the devices.
Not that this helps any… but if I cast my camera from the Eufy app on my phone and then ask my Google Hub to show me… it does cast over. It has to be open and streaming on my phone then Google can access it. I added everything through my Google Home app but Eufy says to add it through G Assistant, I unlinked from G Home and relinked Through G Assistant but it made no difference. It would really be nice to see my Eufy doorbell on my Google hub…
