Complete the required items before setup. Items marked “Not required” are optional for this route.
Documented
Match HS220 and its hardware revision on the unit. This route uses TP-Link integration over Wi-Fi; Matter, HomeKit and vendor cloud linking are separate routes.
Documented
Complete installation using the exact manufacturer guide and load-specific ratings. Wall switches require appropriate wiring and qualified installation; plug-in devices must use a suitable outlet and load.
Derived from documentation
Connect the device to 2.4 GHz Wi-Fi. Home Assistant must reach its local address. Different subnets can prevent discovery; follow the official manual-address guidance.
Documented
Use a working Home Assistant installation.
