2026 verdict
Two Matter valves, one built around Apple: the Eve Thermo takes this smart radiator valve comparison thanks to geofencing and fully local control.
With an Apple home hub it lowers the heat when everyone leaves and raises it before someone returns, and its owners value that it works without a cloud account. The Bosch Smart radiator thermostat II [+M] is the better reviewed valve, adds Zigbee next to Thread, is rated for about 2 years on its AA cells and has a housing its owners call sturdy, but it offers no geofencing. Both support Matter, Apple HomeKit, Google Home, Alexa, SmartThings and Home Assistant, and both have a display, child lock, frost protection and manual schedules, with no external sensor input. Pick the Eve Thermo for an Apple home that wants presence-based heating, and the Bosch Smart radiator thermostat II [+M] for Zigbee or Bosch Smart Home setups.

What the differences mean
Geofencing
The Eve Thermo supports geofencing with an Apple home hub (HomePod, HomePod mini or Apple TV), so heating follows who is home. The Bosch Smart radiator thermostat II [+M] has no geofencing and relies on manual schedules.
Radios
Both run on Thread through a border router. The Bosch adds Zigbee for Bosch's own controller and Zigbee hubs; the Eve adds Bluetooth for direct control nearby.
Battery life
The Bosch is rated for about 2 years on 2 AA cells. The Eve also takes 2 AA cells, but its battery life is not documented.
Build consistency
Bosch owners describe a sturdy housing, while Eve owners report that build quality and motor noise vary from one unit to the next.

What owners say
Owners of both valves value the wide platform support, the child lock and frost protection, and both groups report connections that turned unreliable for some after a while. Eve Thermo owners single out near-instant pairing with Apple Home, several valves that stay in sync, control without an internet connection or cloud account, and geofencing they credit with lower heating bills, while their main complaint is uneven build quality, with motors loud on some units and quiet on others. Bosch Smart radiator thermostat II [+M] owners praise a housing sturdier than the first generation and remote app control, and they warn that pairing with third-party Matter bridges can be inconsistent and that the Zigbee code hides in the battery compartment.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
