Compatibility notes

  • OpenTherm modulating version of the Starck-designed Netatmo thermostat; battery thermostat talks to a boiler-wired relay over radio, relay joins Wi-Fi 2.4 GHz and exposes HomeKit (Tech Advisor review confirms HomeKit).
  • 868 MHz figure for the thermostat-to-relay radio comes from retailer/distributor spec listings of the Netatmo Smart Thermostat family (termix.ro, hellopro.fr), not a Netatmo spec sheet.
  • Netatmo's Jan 2026 'ORIGINAL' range (Thermostat ORIGINAL, Smart Radiator Valve ORIGINAL, Thermo Hub NTG01 Matter 1.3 cert 2026-08-04) is a separate product line; Netatmo marks the ORIGINAL devices as not compatible with the Starck-era accessories, so matter:4129:8 is not linked.
  • No public firmware release notes found.
