I put away my Nest Hub a few years ago because I could not get it to work as a Roon Display consistently. I decided to take it out and play around to see if it would work now. While I was playing around with it, I stumbled on a hack to get my Google Nest Hub working as a Roon Display without timing out after 60 secs. I am not sure if this hack will work for you. Please try it and post your result.
My Google Nest Hub System Firmware: 4.20210608.1.1146075
Cast Firmware: 1.56.291758
My Roon Core version: 1.8 Build 923
Step 1: Open Google Home App on your iPhone or Android and open your Nest Hub
Step 2: Select Settings (Gear icon on top)
Step 3: Select Accessibility
Step 4: Turn on Screen Reader
Once Screen Reader is turned ON, my Nest Hub as a Roon Display stops timing out. It will still “blink” every 60s, but the Roon display stays ON.
The drawback is that now you will see a red box around the display in the accessibility mode. You will also need to figure out how to use your Nest Hub in the accessibility mode (Google Nest display accessibility settings - Android - Google Nest Help). Since I only use my Nest Hub as a Roon Display I don’t interact with my Google Hub. Or you can interact with your Nest Hub using “Hey Google”.
I only have one Google Nest Hub at home, so I am unsure if it will work for you. Post your results here. So far, my Nest Hub as a Roon Display is working well for me.
Edit: Confirmed by a few other users the hack works!
I have Google photo as my screen saver. Try to turn on and off Screen Reader a few times on your Google Home app. Do you see the red box around your Google Nest Hub?
Yes it’s the smaller 7” one. What happens when you click on your screen with screen reader on? On my Nest Hub it will show a red box. That is how I know I am in the accessibility mode.
I just rebooted my Core and Nest Hub. I am able to get it to work consistently again (Roon Display without timing out). If you turn on Screen Reader, try to interact with your Nest Hub. You will find one finger touch does not register with your screen. Try to use 3 fingers to slide left or right. Do you see a red box around menu selections?
No one finger continues to work even with screen reader selected on in the all, looks like its just not letting me turn on screen reader even tho the app says its turned on. odd as all the other options register and turn on immediately.
will keep trying
have tried talking to it asking it to read my screen and it says it cant
interesting you have it working tho thanks, will come back if I manage to get it going and if its a setting that also needs changing
