You got your Tailwind system up and running. You can control your garage door(s) from the app. Cool. Now you're going to the next level and trying to add Tailwind to Google Home / The Google Assistant so you can set up automations and voice control. Then, just as you're wrapping up the account linking process in the Google Home app, you see the "Invalid Credentials" error. Ugh.
We can help you with that.
First and foremost, please make sure you've watched our help video on setting up Google Home with Tailwind.
If you're still getting the "Invalid Credentials" error, it could be caused by special characters in your email address. While Tailwind has no problem accepting special characters, Google does not allow them in your email address.
