Its 15.6-inch Full HD screen, camera with a shutter and 5 and 6 GHz Wi-Fi make it a family command center and kitchen TV, where the Shelly Wall Display is a 4-inch panel in a switch box. The Shelly Wall Display earns its place with broader platform support (Alexa, SmartThings and full Home Assistant), temperature and humidity sensors that let it run the heating, and a 3-year warranty against 1 year. Both hang on a wall, but they do different jobs. Get the Amazon Echo Show 15 for an Alexa home that wants one big shared screen, and the Shelly Wall Display for a Home Assistant or Shelly setup that wants a compact panel and thermostat.

What the differences mean

Screen

A 15.6-inch Full HD screen against a 4-inch panel. The Amazon Echo Show 15 can hold a calendar, lists, camera feeds and a streaming show; the Shelly Wall Display shows a few control tiles and readings next to a light switch.

Voice and camera

The Amazon Echo Show 15 has Alexa built in and a camera with a physical shutter for video calls. The Shelly Wall Display has neither a voice assistant nor a camera.

Hub roles

The Amazon Echo Show 15 is a Zigbee coordinator, Thread border router and Matter bridge. The Shelly Wall Display has no hub role and talks over 2.4 GHz Wi-Fi and Bluetooth only.

Platforms

The Shelly Wall Display works with Alexa, SmartThings and fully with Home Assistant. The Amazon Echo Show 15 works with Alexa and only partially with Home Assistant.

Sensors and heating

Only the Shelly Wall Display reads temperature and humidity, which is why owners use it as a thermostat. The Amazon Echo Show 15 has a motion sensor instead.

Installation and warranty

The Shelly Wall Display replaces a switch or socket and needs a neutral wire, and it carries a 3-year warranty. The Amazon Echo Show 15 hangs on a bracket or sits on a stand and carries 1 year.

What owners say

Owners of both wall devices call them the control center of the room and find setup easy, but they praise and criticise very different things. Amazon Echo Show 15 owners talk about the bright 15.6-inch screen as a household noticeboard, built-in Fire TV that replaced a kitchen TV, customisable widgets and viewing Ring feeds on the big screen, while their complaints are on-screen ads (many can be turned off), an Alexa+ that feels unfinished and does not work in portrait orientation, and a device that is far less useful when Alexa has problems. Shelly Wall Display owners single out native Home Assistant dashboards, the premium build and a thermostat mode that pairs with a separate sensor, and they complain about network drops, a built-in thermometer skewed by the panel's own heat, the neutral wire it needs and a body that does not fit standard multi-gang frames.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
