Specifications to check side by side

Zigbee (connectivity): Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — Zigbee Hub required (Built on Zigbee 3.0 with an EFR32MG21 MCU. It also acts as a Zigbee router, repeating the mesh for other devices, but it still needs a coordinator to join.); TP-Link Kasa HS220 — No.
Switches (features): Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — 2; TP-Link Kasa HS220 — 1.
Apple Home (integrations): Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch — SONOFF Hub required (The switch has no native HomeKit profile. Its product page documents reaching Apple Home over Matter through a SONOFF Matter bridge (ZBBridge-U or eWeLink CUBE).); 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-ZBW2 Zigbee Double Smart Wall Switch — SONOFF Hub required (The switch is Zigbee 3.0, not Matter. Its product page documents reaching Matter platforms through a SONOFF Matter bridge, ZBBridge-U, iHost or eWeLink CUBE.); TP-Link Kasa HS220 — No (TP-Link's Matter compatibility list covers the KS205, KS225, TS15 and TS25 switches, not the HS220).
