Tapo vs ELEGRP Switch Comparison
Smart Home Compatibility
The Tapo S505 supports Matter, allowing integration with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings. This multi-admin feature lets you control lights through different platforms without multiple apps. LAN control ensures smooth operation even if internet access is offline. In contrast, the ELEGRP DM19-BL is a standard digital dimmer with no mentioned smart home protocols or app connectivity. It functions as a traditional wall switch without automation capabilities or remote access features. You cannot schedule or monitor the ELEGRP switch remotely.
Wiring Requirement
Installation needs differ significantly between these two models. The Tapo S505 requires a neutral wire for proper operation, which may complicate upgrades in older homes lacking this infrastructure. The ELEGRP DM19-BL explicitly states that no neutral wire is required. This design makes it ideal for homes of all ages where neutral wiring might be absent. The ELEGRP unit also features an ultra-slim profile that fits easily into electrical boxes. If your existing switch setup lacks a neutral conductor, the ELEGRP option offers a more straightforward installation path without additional wiring modifications.
Switch Function
Functionality defines the core purpose of each device. The Tapo S505 is a single-pole on/off switch. It provides basic smart toggling but lacks dimming capabilities. You can only turn lights fully on or off via the app or voice commands. The ELEGRP DM19-BL is a digital dimmer switch. It utilizes MCU-integrated digital circuit control to provide smooth, gradual lighting adjustments. It supports fade-on functions to reduce inrush current and extend bulb life. If you want to adjust brightness levels rather than just toggle power, the ELEGRP dimmer provides that specific control feature.
Circuit Type
Both switches support single-pole configurations, allowing control from one location. However, the ELEGRP DM19-BL adds versatility by supporting 3-way applications. This allows lights to be controlled from two different locations using one dimmer and standard 3-way switches. The Tapo S505 is listed strictly as a single-pole device. While both handle single-pole circuits effectively, the ELEGRP option offers greater flexibility for rooms where you might want to control lighting from multiple entry points using existing wiring setups. This makes the ELEGRP suitable for hallways or larger rooms.
Certification and Warranty
The ELEGRP DM19-BL holds UL and CUL listings, indicating compliance with safety standards. It comes with a 2-year warranty replacement service and lifetime online technical support. The manufacturer also offers a 30-day money-back guarantee. Specific certification details and warranty terms for the Tapo S505 are not provided in the available data. Without explicit mention of safety listings or warranty coverage for the Tapo model, the ELEGRP offers documented assurance regarding product safety and long-term support. This transparency regarding certification and service terms gives the ELEGRP a clear advantage in this category.
Choose the right switch for your needs
Smart home users wanting app control
The Tapo S505 supports Matter, Apple Home, Alexa, and Google Home. You can control lights from anywhere using the Tapo app. LAN control works even if your internet is offline. Multi-admin lets you use different platforms for the same device. This switch offers full smart automation for your connected home.
Renters or homes without neutral wires
The ELEGRP DM19-BL requires no neutral wire. This makes it ideal for older homes or rentals where wiring is limited. It installs easily in as little as 15 minutes. The slim profile fits standard electrical boxes. You get reliable dimming without needing complex wiring upgrades or a neutral connection.
Users needing 3-way switch capability
The ELEGRP DM19-BL works in single-pole or 3-way applications. You can control lights from two locations. The other switch in a multi-location setup turns the light on at the brightness level selected at the dimmer. This flexibility suits hallways or stairs where multiple controls are needed.
