# Eve Eve Thermostat (Europe)

Eve Thermostat is a focused Matter-over-Thread upgrade for a compatible European underfloor-heating zone. Its local controls are appealing, but the actuator voltage and electrical load must be confirmed before the ecosystem choice matters.

## Ecosystem Support

- Apple Home: Supported
- Google Home: Supported
- Alexa: Supported
- SmartThings: Supported
- Home Assistant: Supported

## Best For

- European homes with compatible 230 V water-based underfloor heating
- Buyers who want direct Matter over Thread without a brand bridge
- Apple Home or Google Home users who want Eve app scheduling

## Skip If

- The heating system uses forced air, radiator valves, or unsupported actuators
- You need one thermostat to control a boiler or heat pump directly
- The existing wiring and electrical load have not been identified

## Setup Notes

- Confirm the existing system uses supported 230 V electrothermal actuators before buying.
- Use a compatible Matter controller and Thread border router from the chosen ecosystem.
- Follow Eve's European wiring guide and use a qualified installer when mains wiring is outside your experience.

## Known Limitations

- Eve does not position this model as a general boiler or heat-pump thermostat.
- The silent Triac output supports a maximum of 65 mA or 15 W.
- Potential-free relay contacts support up to 5 A resistive or 2 A motor loads.
- Eve app schedules currently require Apple Home on iPhone or iPad, or Google Home on Android.

## Pros

- Direct Matter over Thread connection without an Eve hub
- On-device controls and locally stored schedules
- Supports silent Triac control or potential-free relay contacts
- Mains-powered Full Thread Device can relay Thread traffic

## Cons

- Only suitable for compatible water-based underfloor-heating systems
- Requires careful 230 V wiring and load checks before purchase
- Eve app scheduling is limited to Apple Home and Google Home paths

## Start with the actuator, not the app

Eve Thermostat is a European wall controller for water-based underfloor heating. It is built for compatible 230 V electrothermal actuators, not for forced-air HVAC, radiator valves, or every boiler and heat-pump installation.

Before buying, identify the actuator voltage, electrical load, and existing control method. Eve's silent Triac output supports up to 65 mA or 15 W. The potential-free relay contacts support up to 5 A for resistive loads or 2 A for motor loads. Those limits decide whether the thermostat belongs on the wall.

## The Matter path is direct

The thermostat uses Matter over Thread and does not require an Eve hub. It still needs a compatible Matter controller and Thread border router from Apple Home, Google Home, Alexa, SmartThings, or Home Assistant.

Because it is a mains-powered Full Thread Device, it can relay traffic for nearby Thread devices after it joins the network. That is useful infrastructure, but it does not compensate for weak coverage between the thermostat and the rest of the Thread mesh.

## Local schedules depend on the phone platform

Eve stores schedules on the thermostat, so they continue without a phone or internet connection. The path used to create them is narrower than basic Matter control. Eve currently supports schedule creation in its app on iPhone or iPad through Apple Home, and on Android through Google Home.

Alexa and SmartThings can control the thermostat through Matter, but Eve says its app does not currently create schedules through those platforms. Their routines are the practical fallback. Home Assistant is listed as supported for Matter control, but buyers should verify the exact controls exposed by their maintained Matter setup.

## Should you buy it?

Buy Eve Thermostat when a compatible 230 V underfloor-heating zone is already confirmed and a direct Matter-over-Thread controller is the goal. Skip it when the heating circuit is unknown or when one device must manage a boiler, heat pump, radiator, or low-voltage HVAC system.
