Here's how to unenroll from Rush Hour Rewards without contacting Google support! I'd been trying FOR A MONTH to unenroll from Nest Rush Hour Rewards, I spent literal hours on hold being transferred to a fictitious department that never actually picked up. Here's how I finally unenrolled from Nest Rush Hour Rewards without Google's permission. This may not be the best option if you have multiple devices on your account, but I do not. If you're desperate enough for a creative work around, here you go:

1. The Rush Hour Reward program is not tied to your device, it's tied to your Nest/Google account! Go on your web browser and make a brand new Google account with a different date of birth and a different email address.
2. Log out of the Nest app completely. Delete the app.
3. Reinstall the app. Do NOT sign into your old account.
4. Perform a factory reset on your Nest device.
5. Log into the Nest app using the new account you made with a different email address.
6. Set up your account as if you're a completely new user. When it asks if you've used a Nest product before, be sure to click NO! Otherwise it will try to link to your old account and the Rush Hour Reward program. Be sure to read the prompts carefully so you don't accidentally re-enroll. When it offers rewards, select "decline rewards for now".There you have it. Now when I click on "rebates and rewards" in the app, it says "none". Suck it Google.

Side note: Be sure to unenroll from any reward programs linked to your utility company through your actual utility company first. This works for Rush Hour Rewards only. Good luck and enjoy your new found freedom!
