Specifications to check side by side

Zigbee (connectivity): Sonoff Orb-ZBDIM Zigbee Dimmer Wall Switch — Zigbee Hub required (Zigbee over IEEE 802.15.4 on an EFR32MG21 MCU. It also acts as a Zigbee router and repeats the mesh for nearby devices, but it still needs a coordinator such as a SONOFF bridge, an iHost, an NSPanel Pro or a USB dongle to join.); TP-Link Kasa HS220 — No.
Apple Home (integrations): Sonoff Orb-ZBDIM Zigbee Dimmer Wall Switch — SONOFF Hub required (The Orb-ZBDIM has no native HomeKit profile. Its product page carries a "Works with Apple Home Via Matter Bridge" section: a SONOFF ZBBridge-U or eWeLink CUBE republishes the switch into Apple Home over Matter.); TP-Link Kasa HS220 — No (TP-Link's own model comparison lists the HS220 as compatible with Alexa and Google Home only, while its HomeKit dimmer (KS220) is listed as HomeKit/Alexa/Google Home).
Matter (integrations): Sonoff Orb-ZBDIM Zigbee Dimmer Wall Switch — SONOFF Hub required (The switch itself is Zigbee, not Matter. Its product page documents reaching Matter platforms through a SONOFF Matter bridge, the ZBBridge-U or eWeLink CUBE, and SONOFF sells the Orb-DIM as the native Matter version.); TP-Link Kasa HS220 — No (TP-Link's Matter compatibility list covers the KS205, KS225, TS15 and TS25 switches, not the HS220).
Ac Load Voltage (power): Sonoff Orb-ZBDIM Zigbee Dimmer Wall Switch — 220-240V (The specification table rates the switch at 220-240V~ 50Hz, and the product description warns that it is a 220-240V only device, so it is not intended for 110-120V wiring.); TP-Link Kasa HS220 — 120V (Input voltage 100-120VAC 60Hz).
