Eve Thermo (Matter)

Eve Thermo with Matter certification is an intelligent radiator valve that replaces your existing manual or thermostatic radiator valve to bring precise temperature control to hot water heating systems. Now compatible with Apple HomeKit, Amazon Alexa, Google Home, and Samsung SmartThings through Matter over Thread, this fifth-generation valve offers sophisticated scheduling and automation for efficient, comfortable heating.

The compact design features an intuitive interface with capacitive touch controls and clear LED display showing target temperature. Installation is straightforward—the valve screws onto standard M30 x 1.5 radiator threads with included adapters for popular Danfoss valve types. Open-window detection automatically pauses heating when rapid temperature drops indicate an open window, preventing energy waste.

Thread mesh networking provides responsive, reliable communication through any compatible Thread border router. The battery-operated valve functions as a Minimal Thread Device (MTD), conserving power while benefiting from Thread's mesh routing capabilities. Two AA batteries provide months of operation with low-battery alerts before replacement is needed.

Matter certification enables cross-platform scheduling and automation. Create heating schedules in any compatible app, build automations that adjust temperature based on occupancy, or integrate with other Matter devices for whole-home climate control. The valve learns your heating system characteristics for efficient operation. No cloud account required—Matter devices operate locally for privacy and reliability.
