Nest 1/2 Gen Support Stopped — What Should You Do? (2025 Update)

In October 2025, Google ended app and cloud support for the 1st and 2nd generation Nest Learning Thermostats. If you have one of these older models in your UK home, you may have lost access to remote heating control through the Google Nest app or Google Home app.

The good news is that your thermostat may still work as a local heating controller. The bigger question is whether you want to keep using it manually or replace it with a newer smart heating system.

In this guide, we'll explain what happened, what it means for your heating, and what to consider when comparing alternatives such as Tado, Hive and Repenic.

What Happened to Nest 1st and 2nd Gen?

Google discontinued app and cloud support for the 1st and 2nd generation Nest Learning Thermostats on 25 October 2025.

According to Google's announcement, these thermostats would no longer connect to or work through the Google Nest app or Google Home app from that date.

This affects users who relied on the app for remote temperature adjustments and connected heating features.

The thermostat itself may still operate locally, depending on the installation and configuration. However, losing cloud support means that the connected experience these older models were designed to provide is no longer available in the same way.

Google's announcement confirmed the end of support, but it did not provide a detailed public explanation of every technical or commercial reason behind the decision. It is therefore better not to present ageing hardware, maintenance costs or a push towards newer products as Google's confirmed motives.

What Does This Mean for Your Home?

If your household depended on the Nest app, the main change is the loss of remote and connected control.

Depending on your previous setup, you may no longer be able to use the following features through the discontinued service:

• Adjusting your heating temperature while away from home.
• Managing heating schedules through the app.
• Using app-based geofencing and connected automations.
• Accessing certain smart-home integrations.
• Viewing connected heating information that relied on the discontinued service.

Your thermostat may still allow you to adjust the temperature directly on the wall. However, local operation is not the same as having a fully connected smart thermostat.

If you mainly use your thermostat manually, you may not need to replace it immediately. If you rely on remote control, schedules or connected heating features, a replacement is worth considering.

Do You Need to Replace Your Nest Thermostat?

Not necessarily.

Keep your existing Nest: If local temperature adjustment is sufficient for your household, you may be able to continue using the thermostat in its remaining local-control capacity. Check the behaviour of your specific model and heating system.

Replace it with a supported smart thermostat: If you want app-based heating control, remote temperature adjustment or connected scheduling again, look for a replacement system that supports your boiler and existing wiring.

Before buying, check whether your home uses a combi boiler, system boiler or conventional boiler, whether you have separate hot-water control, and whether your heating is divided into multiple zones.

A thermostat that looks similar to Nest may not be compatible with your existing receiver or wiring.

What Are the Alternatives to Nest?

Several brands offer smart heating controls for UK homes, including Tado, Hive and Repenic.

They differ in their supported heating systems, control methods, installation requirements, app features and pricing.

Rather than assuming one is a direct replacement for every Nest installation, compare the functions you actually need:

• Remote temperature control.
• Heating schedules.
• Hot-water control, if applicable.
• Multi-zone heating.
• Smart-home integration.
• Subscription requirements.
• Installation and receiver costs.

For homes with multiple heating zones, the cost of additional thermostats and receivers can make a significant difference to the total installation price.

Tado vs Hive vs Repenic: Which Thermostat Is Right for You?

The best Nest replacement depends on what you want from your heating system. Are you looking for a lower upfront cost, multi-zone control, fewer subscription fees, or a particular smart-home integration?

Which one should you shortlist?

• Consider Tado if geofencing and location-based heating are important to you. Check the subscription requirements and exact UK model compatibility before buying.
• Consider Hive if its supported heating controls and app features suit your household. For multi-zone heating, compare the total cost of additional equipment rather than just the starter kit.
• Consider Repenic if you want to compare a lower listed upfront price, no additional app subscription fees and a multi-zone heating option. Confirm boiler compatibility, supported smart-home integrations and the equipment needed for your installation.

Before making a final decision: Check your boiler type, whether you need separate hot-water control, the number of heating zones, and whether the thermostat can provide the local or cloud-based control you expect. A feature listed for one product generation may not be available in another.

Other Things to Check Before Buying

When replacing an older Nest thermostat, the advertised price and app features are only part of the decision. Boiler compatibility, local control, subscription terms and installation requirements can all affect the long-term experience.

Cloud Dependency and Local Control: What Do Real Users Say?

Subscription fees are not the only thing worth checking when choosing a smart thermostat. For some homeowners, the bigger concern is whether they can continue controlling their heating locally if a manufacturer's cloud service changes or becomes unavailable.

A verified UK Amazon customer review of a Tado X Starter Kit, published on 17 September 2025, raised concerns about subscription requirements, local control and long-term software support.

The reviewer said they had originally chosen Tado because of its Matter support and Home Assistant integration. They were particularly interested in controlling their heating locally through their existing Matter and Thread setup, rather than relying on cloud services.

The review also expressed frustration with the manufacturer's response to questions about firmware updates and future support.

This is one customer's experience, rather than evidence that every Tado user faces the same limitations. However, it highlights some useful questions to ask before buying a smart thermostat:

• Can you control your heating locally, or does it depend on the manufacturer's cloud?
• Which functions are available without a subscription?
• Does Matter support mean full local control, or only access to certain connected features?
• How does the manufacturer communicate firmware updates and long-term product support?

If local control is important to you, don't rely on a Matter or Home Assistant compatibility label alone. Check which functions are supported locally, including temperature adjustments, heating schedules and hot-water control.

Subscription Features

Some smart heating systems offer additional features through a paid subscription.

If you mainly want basic heating schedules, remote temperature control and convenient daily operation, compare which features are included without a subscription.

For features such as geofencing, automatic heating adjustments or open-window detection, check the current subscription terms and whether the feature requires extra sensors.

Repenic's thermostat app features do not require an additional subscription. If avoiding recurring app fees is important to you, check the included functions and current service terms before choosing a system.

Multi-Zone Heating

Multi-zone heating can be useful when different rooms or areas of your home need independent temperature control.

However, a multi-zone installation may require additional thermostats, receivers, wiring or zone valves. These requirements vary between systems.

When comparing Hive, Tado and Repenic, look at the total cost of controlling all the zones in your home rather than the price of a single thermostat.

Repenic supports 1–4 heating zones and that additional receivers are not required for its described configuration. Confirm the precise equipment and wiring requirements for your own installation before purchasing.

Installation and Wiring

Older UK properties may have different wiring arrangements, boiler controls and back-box configurations.

Before replacing Nest, check whether the new system uses a wired thermostat, wireless thermostat with receiver, or a different control arrangement. A replacement may require wiring changes or additional installation work.

For safety and compatibility, have a suitably qualified heating engineer or electrician assess the existing installation where necessary.

Is Repenic a Suitable Nest Alternative?

If you are looking for a smart thermostat without extra app subscription fees, Repenic is one option to consider.

Repenic's Wi-Fi wireless thermostat is designed for smart heating control and offers features such as heating schedules, remote control and multi-zone configurations, depending on the supported system and installation.

For households comparing replacement costs, the potential appeal is straightforward:

• No extra app subscription fees: Repenic does not charge an additional subscription for its app features, according to the product information supplied for this article.
• Multi-zone heating: The Repenic system is described as supporting 1–4 heating zones, with the required configuration and equipment depending on the installation.
• Heating control features: Check the specific thermostat model for supported schedules, Boost, hot-water control and boiler compatibility.
• 5-year warranty: Repenic offers a 5-year warranty, subject to its current warranty terms.

If you are replacing a Nest thermostat, first check the type of boiler you have, the wiring and whether you need separate hot-water or multi-zone control.
