- Matter Yes, over Wi-Fi
- Apple Home Via Matter
- Google Home Via Matter
- Amazon Alexa Via Matter
- SmartThings Via Matter
- Home Assistant Yes
At 29 x 34 x 16 mm, the Shelly 1 Mini Gen4 is a single-relay module rated 8 A at 240 V AC, small enough for tight wall boxes. It needs a neutral wire and has no power metering or dimming. The default firmware is Matter over Wi-Fi, so Apple Home, Google Home, Alexa and SmartThings can add it without a hub; Alexa goes through Matter, not a Shelly skill.

|---|---|---|
| Matter | Yes, over Wi-Fi | CSA lists Shelly 1 Mini Gen4 (CSA250D6MAT45096-24, Matter 1.3, firmware 1.3.0-s2, Wi-Fi and Bluetooth). The listing's description text names the 1PM, a copy error. Shelly's page also says it is Matter-certified.[1],[3] Other Matter smart switches |
| Apple Home | Via Matter | Through Matter in the default firmware. Needs an Apple home hub for remote use and automations.[3] |
| Google Home | Via Matter | Through Matter. Shelly's pages name Google and mark Google Smart Home traits 'Yes' without saying how, so only Matter is claimed.[1],[3] |
| Amazon Alexa | Via Matter | Through Matter. Shelly's spec table marks Alexa 'Yes' without saying how, and Shelly's Alexa guide doesn't name this model, so only Matter is claimed.[2],[3] |
| SmartThings | Via Matter | Through Matter. Shelly's pages also name SmartThings; the route is not stated.[1],[3] |
| Home Assistant | Yes | Official Shelly integration with local push, covering all Shelly generations. It can also be added through Matter.[4] |
“Via Matter” means you add it with that platform's Matter controller instead of a brand skill or app. “Unconfirmed” means we couldn't find an official source either way. How we verify.
Specs that matter for setup
- Radio: Wi-Fi, Bluetooth and Zigbee. Matter over Wi-Fi is the default profile; five button presses switch it to the Zigbee profile.
- Hub: Wi-Fi device that pairs through Matter or the Shelly app. Zigbee mode needs a Zigbee coordinator, but the default does not.
- Local control: Shelly lists an embedded web interface and standalone Wi-Fi operation with schedules, scenes and local actions; Home Assistant's integration uses local push.
- Form: Compact 29 x 34 x 16 mm relay that fits behind sockets and switches.
- Dimmer: On/off relay, 8 A at 240 V AC; no dimming and no power metering listed.
- Needs neutral wire: Shelly's product page FAQ says it requires a neutral wire for proper operation; the supply uses N and L terminals.
- Gangs / channels: Single potential-free relay output with one switch input.
