Smart plugs: either. We list 8 certified Tapo plugs (including an outdoor plug and a power strip, by their names) and 2 certified Meross plugs. All use Wi-Fi. (our catalog)
Wall switches and dimmers: Tapo. Meross has no certified switch in our US list. (our catalog)
A thermostat or a Thread sensor: Meross. Its MTS300MA thermostat and MS605 presence sensor are certified; the MS605 uses Thread, so it needs a Thread border router. (our catalog)
Setting up: TP-Link recommends adding its devices in the Tapo app first, then sharing them to your platform; after a Tapo-app setup you have 15 minutes from power-on to also add the device to another Matter app. (TP-Link, read Oct 21, 2026)
