Shelly is the smart home brand of Allterco, a Bulgarian company that now trades as Shelly Group. Its small Wi-Fi relays, dimmers, plugs, energy meters and sensors are meant to sit behind existing switches and sockets, and the range has grown to include Bluetooth, Zigbee, Z-Wave and Matter models.
Most Shelly devices join your Wi-Fi network directly, with no hub. They can run through Shelly's cloud for remote access, but they also keep a local interface, and they publish a documented local API (HTTP, WebSocket, MQTT and, on first-generation devices, CoIoT). Newer Gen3 and Gen4 devices add Bluetooth, Matter over Wi-Fi and, on Gen4, a Zigbee mode, and the Wave line uses Z-Wave.
That suits people who want to retrofit existing wiring and keep control local, especially with Home Assistant, openHAB or Node-RED. It is less simple if you want Thread, because Shelly says it does not plan Matter over Thread, or if you want one radio across the whole range, because the protocol depends on the generation and product line.

The current app, published by Shelly Europe. Set-up, dashboards, schedules, rooms, scenes, energy tracking and alerts. A Shelly account is required. Devices can be controlled through the cloud or, with local control on, over the home network, though battery-powered devices such as the H&T Gen3 need the cloud to work fully. Google Play says it succeeds Shelly Cloud. We did not confirm store links for Shelly Cloud itself.

Connection
Wi-Fi
Yes
Wi-Fi is the main connection. openHAB's binding notes say Shelly devices use 2.4 GHz and IPv4 only. Gen3 and Gen4 can run as an access point and a Wi-Fi client at the same time, and Gen4 adds Wi-Fi 6. The Pro line can use LAN and Wi-Fi together.
Gen3 and Gen4 use Bluetooth to ease set-up and can act as gateways for the Shelly BLU line, except the BLU TRV. Home Assistant says its Shelly integration is not meant for BLU sensors, which go through its BTHome integration, and that the BLU TRV needs a BLU Gateway Gen3 or similar.
Only Gen4 includes Zigbee. On the Shelly 2PM Gen4, Zigbee is a firmware mode rather than a gateway role: the device can extend a Zigbee network and joins an existing hub, and the page does not describe it as a hub. Shelly's API also has a Zigbee-through-RPC feature for sending Zigbee commands to devices on the network.
The Shelly Wave line (sold with the Qubino name) is Z-Wave. The Wave 1 page lists S2 security and says it works with certified Z-Wave gateways. Shelly's SmartThings announcement names the Wave Plug US as a certified Z-Wave plug. We could not confirm whether Wave 1 supports Z-Wave Long Range.
All Gen4 devices and selected Gen3 models support Matter over Wi-Fi, with no hub or Thread network. Gen3 devices usually need firmware 1.6 or later and Matter turned on in settings. Shelly names Apple Home, Google Home and Alexa as example platforms. The pages we read describe Shelly devices as Matter devices only, and we found no bridge or controller role. Shelly says Matter in Apple Home exposes only basic power data, with deeper features in the Shelly app.
Documented. In the Google Home app, add a device through Works with Google, find Shelly Smart Control and sign in with a Shelly Cloud account. The article does not mention a local path. Matter is a second route on supported devices.
Shelly describes its devices as compatible with Alexa, including routines and voice control. The pages we read give no model list and do not say whether the link runs locally or through the cloud.
Through Matter, not native HomeKit. Shelly lists Gen4 devices and several Gen3 devices as working this way and says HomeKit via Matter is still limited for complex setups. Remote access and automations need a HomePod, Apple TV or iPad as home hub.
Shelly's compatibility page says SmartThings is covered, and Shelly's announcement names the Wave Plug US as a SmartThings-certified Z-Wave plug, with a goal of certifying most of the range. We could not confirm how Wi-Fi devices connect to SmartThings from these pages.
A built-in integration (since version 0.115) covering Gen1 through Gen4. It talks to the device directly with no cloud, and its IoT class is Local Push. Gen1 uses CoIoT and Gen2 and later use RPC. Mains-powered Gen2 and later devices can act as Bluetooth proxies for advertisement data. Shelly also publishes its own Home Assistant guide.
Homey lists a Shelly Control app as the official Shelly app. A forum thread names Drenso as its developer and says it is mostly local, with Gen2 and later devices as the stated goal. Zigbee devices need Homey Pro, Pro mini or Homey Bridge, and Matter devices are not available on Homey Cloud. An older Shelly (Legacy) app by Allterco remains the official app for first-generation devices and lists Homey Bridge as required for its LAN drivers.
The Shelly binding is in openHAB's add-on list. It controls Gen1 through Gen4 and BLU devices locally and independently of Shelly's cloud, using CoAP for Gen1 and WebSockets for Gen2 and later. BLU devices need a Plus or Pro gateway running a script that the binding installs.
A community package, node-red-contrib-shelly by a single maintainer, covers Gen1 to Gen4, BLU devices and the Shelly Cloud API over local HTTP, webhooks and scripts. It is not an official Shelly product.
Hubitat's documentation lists a Shelly Wi-Fi Integration app for compatible Shelly Wi-Fi devices. We could not read the page body, so supported devices and whether it runs locally are unconfirmed. Shelly's compatibility page also names Hubitat.
Shelly's compatibility page names Domoticz. A community plugin on Codeberg, a fork of another third-party plugin, targets Gen2 and later devices and lists only a few Gen3 plugs and minis as tested.
Shelly's compatibility page names Control4. The driver we found is a paid Chowmain package that uses local IP control for Gen1 and Gen2 devices, and its page does not say Shelly endorses it.
Shelly's compatibility page also names KNX (KNXnet/IP), REST, MQTT, HomeSeer, Crestron, ioBroker, Nymea, Symcon, Tasmota and others, with little detail.
No Philips Hue integration found when we searched Shelly's guide and compatibility pages.

Unconfirmed
No Shelly service found on Shelly's own pages. A user forum post describes triggering a relay through IFTTT webhooks and Shelly's cloud, which is a workaround and not an official integration.

Shelly local API
Official
Gen2 and later devices use JSON-RPC 2.0 over HTTP, WebSocket and MQTT, with UDP available but off by default, and can open an outbound WebSocket to a server. Gen1 devices have an HTTP REST API, MQTT and CoIoT. Shelly's own notes say Gen1 devices do not support secure MQTT, and Gen2 and later allows only six simultaneous non-persistent RPC channels.
An OAuth-based HTTP and WebSocket API for controlling devices and receiving status events on your account. It is documented as work in progress and as the bare minimum. DIY users use a shared client ID, and third-party integrators must ask Shelly for their own. No numeric rate limits are published, though the page says DIY tokens may be rate restricted.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
