Compatibility notes

Starck-designed on/off smart thermostat: battery thermostat (3x AAA) communicates with the boiler relay over long-range radio (868 MHz, up to 100 m per retailer specs); relay connects over Wi-Fi 802.11 b/g/n 2.4 GHz.
HomeKit support added by Netatmo in 2018 (HomeKit News, 2018-04-01).
Netatmo UK page (retrieved 2026-10-14) still sells the product and states it is not compatible with the newer Radiator Valve ORIGINAL; the ORIGINAL line's Matter Thermo Hub (matter:4129:8) is therefore not linked.
Model code NTH01 comes from retailer/manual listings, not a Netatmo spec sheet; NAPlug relay naming is common usage but not confirmed by a fetched source.
