The TP-Link Tapo S515 is a Wi-Fi smart light switch for single-pole, 3-way or 4-way lighting circuits. In a 3-way or 4-way circuit, TP-Link says only one S515 can be used: it must go where the line (live) wire is, and the other switches stay as standard switches. The Tapo app adds remote on/off, schedules, an away mode that switches lights at random, and Smart Actions triggered by Tapo sensors.

Quick answers
- Is this switch Matter certified?
- Yes. MatterCatalog matches it to CSA Matter certificate CSA24753MAT44550-24, certified Dec 10, 2024.
- Does this switch work with Apple Home or HomeKit?
- Likely. It is Matter certified (certificate CSA24753MAT44550-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Apple Home on a page we hold. Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. Apple’s Matter page lists lights among the accessory types the Home app supports.
- Does this switch work with Google Home?
- Likely. It is Matter certified (certificate CSA24753MAT44550-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. Google’s supported-device-types page lists the On/Off Light type.
- Does this switch work with Alexa?
- Likely. It is Matter certified (certificate CSA24753MAT44550-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold. Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does.
- Does this switch work with Samsung SmartThings?
- Likely. It is Matter certified (certificate CSA24753MAT44550-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named SmartThings on a page we hold. SmartThings adds Matter devices through the SmartThings app and a Matter controller.
- Does this switch work with Home Assistant?
- Likely. It is Matter certified (certificate CSA24753MAT44550-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Home Assistant on a page we hold. Home Assistant says: “Adding a new Matter device only works in the Home Assistant Companion app.”
- Does this switch use Thread or Wi-Fi?
- Wi-Fi. Its catalog record lists Wi-Fi, so it joins your Wi-Fi network and does not need a Thread border router. You still need your platform’s Matter controller.
- Does this switch need a hub or a Thread border router?
- No hub of its own and no Thread border router: it joins your Wi-Fi network. You still need your platform’s Matter controller (a smart speaker, display, streaming box or hub), though Apple says an iPhone using iOS 18 or later can add Matter accessories without a home hub.
- When was this switch Matter certified?
- The CSA certified it on Dec 10, 2024 (certificate CSA24753MAT44550-24). That is its certification date, not a retail release date, which MatterCatalog does not state.
- Where can I buy this switch?
- MatterCatalog has verified store links for it at Amazon and TP-Link Tapo. Check the current price, model and pack size at the store.
