Since the app was renamed to Cast a text to Google… I’m having some issues with Google home devices disappearing from the list of selectable devices in the app. These devices will be back after the app is restarted, but this happens several times a day.
As a result, many flows do not work as they should because the selected Google device no longer appears in the list at that time.
What is the status of that Nest Audio when added as Chromecast device ? I don’t have so many devices like you yet I see unavailability of “smart speakers” quite often and it’s not related to the Cast a text app at all - anyway, best would be to create a diag. report to eventually create issue on GitHUB, as the original author is not visiting this forum anymore. Please note that the GitHub link is even not included on the Homey app store
Support
The developer of this app does not offer direct support.
The Nest audio is available, no red exclamation mark or something like that.
It just happened after the app had changed it’s name, before that I never had any issues and I had the same amount of Google devices.
There are more issues with Homey and Google. Every day at 12:00 Google syncs all devices and almost every day it can sync all added apps except for Homey. Even when the Google assistent is turned on in Homey. I know this will be automatically disabled from time to time.
Never got an answer from Athom or Google if the issue is on their side?
