Shelly devices can be controlled by voice and used in routines through Amazon Alexa. This page is a short overview of how the integration works, what it supports today, and where its limits are.
What is Amazon Alexa
Amazon Alexa is Amazon's voice assistant and smart home platform. It runs on Echo speakers and displays and in the Amazon Alexa app, where users group devices into rooms, control them by voice and build routines.
How the integration works
There are two ways to bring Shelly devices into Alexa.
1. Cloud-to-cloud: the Shelly Cloud skill
-
The user links their Shelly account to Alexa by enabling the Shelly Cloud skill. Linking can start from either app: in Shelly Smart Control (Settings > Amazon Alexa > Enable skill > Link) or in the Alexa app (search for Shelly Cloud > Enable to use > sign in with the Shelly account).
-
After linking, Alexa discovers the devices in the Shelly account and shows them with the names given in the Shelly app.
-
A voice command goes from the Echo device to Amazon's cloud, then to Shelly Cloud, then to the Shelly device. State changes and sensor readings travel the other way, so Alexa always shows the current state.
2. Local: Matter
-
Shelly Gen4 devices support Matter out of the box. Gen3 devices support it from specific firmware versions, after Matter is enabled on the device.
-
A Matter-enabled Shelly device can be added directly to an Echo device that acts as a Matter controller. Commands then stay on the local network, without going through Shelly Cloud.
