Product notes
On TP-Link Matter list. v0.12: Tapo product page + datasheet: Matter-certified Wi-Fi single-pole on/off load switch (no 3-way, no dimming); Apple/Alexa/Google/SmartThings. CSA certs per catalogs: CSA22475MAT40475-24 (FW 1.0.0), CSA2519CMAT45294-24 (FW 1.3.0). v0.90: re-typed switch_button -> on_off_light. CSA DCL model VID 0x1188 PID 0x0201 (partNumber S505) primary device type 0x0100 On/Off Light; both certs end product, Wi-Fi + Bluetooth. No Generic Switch secondary endpoint found, so not listed under switch_button. Dimmer sibling S505D is 0x0101 Dimmable Light (separate SKU, not in pack).
v0.90 re-type (High): CSA DCL primary 0x0100 On/Off Light (load switch) per the v0.89 switch_button rule; moved switch_button -> on_off_light like Kasa KS205 (v0.53). Confidence unchanged.
How it differs from the type answer
- In-wall single-pole on/off load switch (neutral required): no dimming and no wired 3-way; the separate S505D dimmer certifies as Dimmable Light 0x0101.
- Matter over Wi-Fi: no Thread border router needed, only the platform's Matter controller.
- 3-way kits (S515 / S515D) are separate SKUs.
