TP-Link expands Matter portfolio with new Tapo smart relay modules

TP-Link, a major maker of smart home and network devices, has expanded its Tapo product line with two smart relay modules designed to convert traditional lighting and appliances into smart devices.

The Tapo Smart Relay Module and Tapo Smart Switch Module received Matter 1.3 certification earlier this month. The former is intended for curtain motors with Matter Bridge capabilities, while the latter is for general purposes, such as garage doors and light switches.

Tapo Smart Relay Module

The Tapo Smart Relay Module, model S112, is primarily designed for shutters and includes native energy monitoring via Matter, according to certification filings. The product is listed on the CSA website with a primary device type of Window Covering, but it can simply function as a power meter or on/off switch.

Protocol Implementation Conformance Statement files indicate that the Tapo Smart Relay Module can also act as a Matter Bridge, connecting other devices to Matter.

Tapo Smart Switch Module 

The Tapo Smart Switch Module, model S110e, is a general-purpose relay with both wet and dry contact modes. It can control alternating current devices, such as lights and fans, without level control and trigger direct current-powered devices such as motorized shutters and garage doors.

PICS files show it is a less powerful device compared with the Tapo Smart Relay Module S112, functioning as an on/off light with a power monitoring feature.

The power monitoring can be bidirectional like its sister S112, allowing it to be used as a power generation meter on devices like solar panels.

Shake-ups in the niche market

Smart relays are typically favored by tinkerers who have the technical expertise for installation rather than users seeking plug-and-play solutions. Brands like Sonoff and Shelly have built their reputation on offering highly customizable devices with advanced features, often at the expense of ease of use.

TP-Link’s entry into this space signals a shift, while SwitchBot’s launch of Matter-compatible relays last year aimed to absorb technical users.

Sonoff has introduced two Matter-certified relays, while Shelly’s models have only recently received certification. However, both lack Matter 1.3 support and power monitoring – potential drawbacks in a competitive market.
