Introduction
Google has announced it will end support for original Nest thermostats, marking the sunset of one of the first smart home devices that revolutionized home automation. This decision affects Nest Learning Thermostat (1st Gen) and Nest Thermostat E, leaving users questioning the future of their smart thermostats and broader Google Nest ecosystem.
In this in-depth guide, we’ll explore:
✔ Why Google is discontinuing support
✔ Which Nest thermostat models are affected?
✔ What happens to your device after support ends?
✔ Best alternatives & upgrade options
✔ Impact on the smart home industry
1. Why Is Google Ending Support for Nest Thermostats?
Google’s decision aligns with its broader product lifecycle strategy, where older devices eventually lose software updates and cloud services. Key reasons include:
A. Aging Hardware Limitations
- 1st-gen Nest thermostats (2011-2015) lack modern processing power for new AI features.
- Nest Thermostat E (2017) has a simpler design but can’t support newer Matter/Thread smart home standards.
B. Focus on Newer Models
Google wants users to transition to:
- Nest Learning Thermostat (3rd Gen & 2020 Edition)
- Nest Thermostat (2021, budget model)
- Future Google Home integrations
C. Cost-Cutting & Streamlining
Maintaining legacy software for older devices is expensive. Google is prioritizing Google Home app unification over Nest app support.
2. Which Nest Thermostat Models Are Losing Support?
| Model | Release Year | Support End Date | What Stops Working? |
|---|---|---|---|
| Nest Learning Thermostat (1st Gen) | 2011 | April 2024 | App control, remote adjustments, software updates |
| Nest Thermostat E | 2017 | April 2024 | Google Assistant, auto-schedule learning, cloud backups |
⚠️ Important Note:
- Physical controls (manual temperature adjustment) will still work.
- Nest Protect (smoke alarms) and Nest Cam are unaffected.
3. What Happens to Your Nest Thermostat After Support Ends?
A. Basic Functions Remain
✔ Manual temperature adjustment
✔ On-device scheduling (if already set)
B. Losing Smart Features
❌ No more remote control via Nest/Google Home app
❌ End of software updates & security patches
❌ Google Assistant/Alexa voice control disabled
❌ Auto-learning schedules stop improving
C. No More Cloud Backups
Your thermostat settings won’t sync if you reset or replace the device.
4. Best Replacement Options for Nest Thermostat Users
If you’re affected, consider upgrading to:
A. Google’s Newer Models
- Nest Learning Thermostat (3rd Gen, 2020) – Best for AI learning & sleek design.
- Nest Thermostat (2021, Budget Model) – Affordable, works with Google Home.
B. Competing Smart Thermostats
- Ecobee SmartThermostat – Best for Apple HomeKit & Alexa users.
- Honeywell Home T9 – Great for multi-room sensors.
- Emerson Sensi Touch – Works with Matter/Thread.
5. Impact on the Smart Home Industry
Google’s move signals:
- Faster obsolescence of older smart home devices
- Shift toward Matter/Thread compatibility
- More reliance on cloud-dependent ecosystems
💡 Key Takeaway:
If you own an older Nest thermostat, plan your upgrade now before losing smart features.
Conclusion: Should You Upgrade?
While 1st-gen Nest thermostats will still function as basic thermostats, losing app control and AI features reduces their value. If you rely on remote adjustments, voice commands, or smart scheduling, upgrading to a newer model is the best choice.
For Google Home users, sticking with Nest Thermostat (2020/2021) ensures long-term support. For those exploring alternatives, Ecobee and Honeywell offer strong cross-platform options.
