Features going backwards on Gen 4 therm

[Kdilo]

Ordered a Nest gen 4 thermostat since my gen 1 will be bricked in October by Google. FYI, you must use Google Home application to install the thermostat and it will NOT show up in the Nest application. Also, Nest Protect devices will NOT show up in the Google Home application so you have to use two applications to manage your Nest devices.

Also, my gen 1 Nest thermostat would let me run my furnace fan 24/7. The gen 4 thermostat will not allow that functionality and you must manually restart the fan running on a weekly basis. All confirmed by tech support on 5/2/25. No known timeline on getting all devices to show up in Google Home application. 

Thanks Google for forcing migration to new devices and applications to retain features and then not providing integration in your ecosystem.

Honestly, at this point after they announced they'll stop supporting the first generations or thermostats there is zero reason to buy anything from Google anymore. Especially not the thermostats.

Who's to say they won't stop supporting those in a few years either?

Remember when thermostats were a lifetime thing you just had hanging on your wall until the end of time?

Not if Google has any say in it!

Hi @Kdilo,

Thank you very much for reaching out to this community! Regarding what happened with your Nest Learning Thermostat 1st gen, which will no longer be supported from October onwards, and that you could use the fan 24/7, but on the new Nest Learning Thermostat 4th gen, there are several factors that could be affecting it:

• The compatibility of the thermostat with your system.
• The configuration of your thermostat.
• The capacity of your HVAC system.
• The fan schedule might not be working properly.

For these potential reasons, please contact us by phone to ensure we handle your case correctly. The phone number is no longer in use. To get in touch with us, visit our Contact Us page and follow the prompts until you reach Contact Options. Then select “Get a Call” or “Chat.” Our team has the necessary information and resources to provide you with the available options to resolve this inconvenience.

Regarding your Nest Protects only being viewable in the Nest app, they are currently available to be used in the Google Home app, but there are certain criteria that need to be met to obtain this. You can visit this help center about Nest Protect now available in the Google Home app.

I'll look forward to your response.

Best regards,

Eduardo

Thanks for the response. I believe that I have figured out and resolved my issues. I found the fan settings in the Google Home application and also successfully merged the Nest Protect devices into the application. Now seeing if everything operates properly. It would have been easier if the tech support agent i spoke with who informed me that neither of the options were available was informed about the features.
