X-Sense SBS50 Base Station

The specifications enumerate the radios as IEEE 802.11b/g/n Wi-Fi plus the 915 MHz (US) and 868 MHz (EU) sub-GHz link to the alarms, with no Bluetooth

Sub-devices join over X-Sense's own Link+ Pro radio at 915 MHz (US) or 868 MHz (EU), not Zigbee

The CSA certified-products database lists only the separate SBS0A Matter base station for X-Sense; the SBS50 has no Matter certification and exposes its sub-devices through the X-Sense app instead

Links only X-Sense alarms and sensors (smoke, CO, combo, water leak, thermo-hygrometer) over its own 915/868 MHz radio, up to 50 devices; no other brands.

Official specifications list a 2.4 GHz Wi-Fi frequency and IEEE 802.11b/g/n as the wireless protocol

X-Sense states the base station is compatible with 2.4 GHz Wi-Fi only and is not compatible with a 5 GHz network

Wi-Fi is the only uplink; the specifications list no wired network port

X-Sense states one SBS50 manages up to 50 devices, with a cap of 10 STH51 thermo-hygrometers among them

The base station relays alarms to the X-Sense cloud and has no card slot or local storage of any kind

Powered by its bundled adapter (input 100-240 V AC 50/60 Hz, output 5.0 V 1.0 A) and has no Ethernet port at all

Built-in sounder rated at 100 dB, adjustable, that sounds together with every connected alarm

No microphone or voice feature is listed in the official specifications; the unit only signals with its LED and its sounder

X-Sense advertises Alexa as the only voice platform for its base station line and claims no Google support on the product page or the collection listings

X-Sense tags its base-station devices as Alexa Compatible, and the Amazon listings for the SBS50 accessories (the SKP0A keypad, the SDS0A door sensor and the SMS0A motion sensor) state Compatible with Alexa, Requires SBS50 Base Station, so the base station is the Alexa bridge for the system

X-Sense claims no HomeKit support for this model, and the SBS50 is not Matter certified so it has no Matter path into Apple Home either

X-Sense claims no SmartThings support for this model, and the SBS50 is not Matter certified so the automatic Works with SmartThings grant does not apply

X-Sense states that its Home Assistant compatibility runs through the SBS50 base station ecosystem, and the python-xsense library behind the community HACS integration maps SBS50 explicitly as a base station entity

The base station reads temperature only from the STH51 and STH0A thermo-hygrometers paired to it; the 4.4-37.8 C figure in its specifications is its own operating range, not a reading it takes

Humidity comes from the paired thermo-hygrometers; the 0-85% RH figure is the base station's operating range

The three-colour LED is an indicator, not an ambient light sensor

Motion is detected by the separate SMS0A sensor, which reports through the base station
