About Kasa (TP-Link)
Kasa is TP-Link's consumer smart home brand and consistently dominates the "best budget smart switch" category for good reason: the switches are well-built, the app is polished, and the price is hard to argue with. A Kasa EP25 at $19 delivers a reliable Wi-Fi switch that works with Alexa and Google out of the box, with no hub required.
What separates Kasa from cheaper alternatives is build quality and software consistency. The TP-Link app is responsive, automations work reliably, and Kasa devices have been around long enough to have a deep track record. Their newer ES20M and similar models add Matter support, making Kasa a viable future-proof option at budget prices.
The limitation is cloud dependency. Standard Kasa switches route commands through TP-Link's servers, which means a cloud outage (rare but it has happened) can affect operation. Local control is available via the Home Assistant Kasa integration, which communicates directly over your LAN — making Kasa a surprisingly capable local-control option for HA users who want low cost.
