Shelly Wall Display X1i Review: A Compact 4 Inch Wall Panel With a Relay Behind It
The Shelly Wall Display X1i is a 4 inch touch panel that drops into a standard flush-mount wall box and replaces a light switch instead of sitting on a shelf. Its interchangeable power base carries a relay rated 5 A at 240 V, so the panel still switches the circuit it is wired to, and Wi-Fi 6 dual band plus Bluetooth 5.0 mean it needs no gateway of its own. It gathers Shelly devices, scenes, schedules and room power consumption on screen, and it answers to Home Assistant, Alexa, Google Home and SmartThings. The trade-off is that it measures almost nothing itself: there is no humidity and temperature sensor on board, so thermostat duty depends on a paired Shelly BLU H&T.
- Shelly households
- In-wall light control
- Home Assistant dashboards
- Flush-mount installs
Pros
- Installs in a standard flush-mount wall box and keeps switching the circuit through its 5 A power base
- Interchangeable power base, upgradeable to a two output version
- Wi-Fi 6 on 2.4 and 5 GHz plus Bluetooth 5.0, with no separate gateway to buy
- Works with Home Assistant, Alexa, Google Home and SmartThings, plus local MQTT and webhooks
- Proximity, gesture and light sensors wake the screen and adapt its brightness automatically
- 4 inch 5-point capacitive colour touchscreen at 720 x 720, with a 1 W speaker for alerts
Cons
- No humidity and temperature sensor on board, so room readings need a paired Shelly BLU H&T
- No Zigbee or Thread radio, so it cannot host or bridge devices on those protocols
- Touchscreen only, with no physical volume, playback or microphone controls
- Apple Home arrives with the announced Matter firmware, which has not shipped yet
- Needs a neutral wire and a flush-mount box, so fitting it is wiring work
Who is the Shelly Wall Display X1i for?
This is a wall control panel for a home already running Shelly hardware, or about to. It installs in a standard flush-mount wall box in place of a switch, wired to line and neutral on screw terminals, and its interchangeable power base keeps the local circuit working: one output rated 5 A at 240 V, upgradeable to the two output power base Shelly sells for the same panel. On screen it collects Shelly devices, scenes, schedules and the power consumption of the Shelly PM devices in the room, on a 4 inch colour touchscreen at 720 x 720 driven by a quad core Rockchip processor with 1 GB of RAM and 8 GB of flash. It suits a household that wants the smart home reachable from the wall rather than from a phone, and the square flush-mount format means it belongs where a switch already is, not on a countertop.
What the Shelly Wall Display X1i offers
Connectivity is where this generation moves on: Wi-Fi 6 on both the 2.4 and the 5 GHz band, plus Bluetooth 5.0 to reach Shelly BLU accessories and to send audio out to a Bluetooth or Sonos speaker. Local control is taken seriously, with MQTT and webhooks alongside the Shelly Smart Control app, and Home Assistant, Alexa, Google Home and SmartThings all documented as supported. The panel wakes on its own: a proximity sensor and gesture sensing bring the screen up as somebody approaches, while a light sensor adapts the brightness and can drive automations on the measured lux. A 1 W speaker handles notifications and alarms, power comes either from the mains base or from USB-C, and the whole assembly is 86.5 mm square, 35.7 mm deep and 163 g, in black or silver.
What to know before you buy
The panel carries no humidity and temperature sensor of its own, so a paired Shelly BLU H&T is what turns it into a room thermostat, and that is a separate purchase. Its radios are Wi-Fi and Bluetooth only, with no Zigbee or Thread on board, so it cannot host devices on those protocols or carry them into another ecosystem. Everything happens on the glass: there are no physical buttons at all, which also means no hardware volume, playback or microphone controls even though a microphone is fitted. Apple Home is the one platform still pending, and Shelly has announced firmware 2.8.0 to close it, turning the Wall Display family into a Matter controller and a Matter device so that any Matter system can add the panel relay, dimmer and thermostat; that firmware had not shipped when this was written. Installation needs a neutral wire and a flush-mount box, which is wiring work rather than a plug-in job, and the warranty runs two years.
Is the Shelly Wall Display X1i worth it?
As a smart display it is doing something most of the category does not: it replaces a switch and keeps switching it, so the wall still works for everyone in the house whether or not the automation does. For a Shelly home that, plus local scenes, MQTT and Home Assistant support, makes it the natural control surface, and the compact square format fits where a switch already sits. Against a larger panel it gives up screen area and physical media buttons, and against a hub style display it gives up Zigbee, Thread and any bridging role. If the home runs on Shelly and the box in the wall has a neutral, it earns its place; if the point is to unify many brands on one screen today, it is worth waiting for the announced Matter firmware first.
Frequently asked questions
Does the Shelly Wall Display X1i need a hub?
No. It joins Wi-Fi 6 on either the 2.4 or the 5 GHz band and carries Bluetooth 5.0 of its own, so it reaches Shelly BLU accessories directly and talks to the Shelly Smart Control app, to MQTT and to webhooks with nothing in between.
Can it switch the light it replaces?
Yes. The interchangeable power base holds a relay rated 5 A at 240 V and one switch input, so the panel controls the circuit it is wired into for resistive, capacitive and inductive loads. Shelly sells a two output power base for the same panel when one load is not enough.
Does it work with Home Assistant?
Yes. Shelly documents Home Assistant support alongside MQTT and webhooks, so the panel and its relay can be driven from an existing Home Assistant install over the local network.
Does it measure room temperature and humidity?
Not on its own. Shelly states the panel has no humidity and temperature sensor, and a Shelly BLU H&T has to be paired to it to read the room and run its thermostat. It does carry a light sensor and a proximity sensor of its own.
Will it show up in Apple Home?
Shelly has announced firmware 2.8.0, which makes the Wall Display family both a Matter controller and a Matter device, so any Matter system can add the panel relay, dimmer and thermostat. Until that update arrives the panel is driven from the Shelly app and through Alexa, Google Home, SmartThings and Home Assistant.
What size wall box does it fit?
A standard flush-mount electrical box. With its power base the panel measures 86.5 x 86.5 x 35.7 mm and weighs 163 g, and it wires to line and neutral on screw terminals, with USB-C available as an alternative supply.
