About this product
When you want to make a light or a gate smart but the wall box is already cramped, the Shelly 1 Mini Gen3 solves it: at 29x34x16 mm it hides behind the existing switch with no new frame and no wall chasing. The relay switches loads up to 8 A / 2000 W at 240 VAC (5 A / 150 W at 30 VDC) and uses a dry (potential-free) contact, so it can also drive equipment with its own power supply - a boiler, a gate motor, irrigation - not just bulbs. A separate SW input keeps the physical switch working in parallel with app control. The 8 MB Gen3 chip adds 2.4 GHz Wi-Fi 802.11 b/g/n, Bluetooth 4.2, scripting, schedules and MQTT for local control without the cloud. It integrates with the Shelly app, Home Assistant, Google Home, Amazon Alexa and SmartThings. Power draw is below 1.2 W with no power metering - for energy measurement choose the 1PM Mini version.

Where it works
Use cases
In a Chisinau apartment the hallway light turns on in the evening and off when you leave, while the physical switch keeps working.
Fitted behind the existing switch, it controls the light from the app and via schedules.
You open the yard gate from the app as you arrive home, with no separate remote.
The dry contact drives the gate motor without interfering with its power supply.
Garden irrigation starts at set hours in summer, controlled locally via Home Assistant without internet.
Controls equipment with its own power supply on a schedule or scene.

Frequently asked questions
Does it need a neutral at the box?
Yes. The module is powered by 110-240 VAC and needs both line and neutral at the box. In older wiring without a neutral at the switch you must run a neutral wire or mount the module in the panel.What maximum load can it switch?
Up to 8 A / 2000 W at 240 VAC and 5 A / 150 W at 30 VDC. The contact is a dry NO type with no overload protection, so do not exceed these ratings.Does it measure energy consumption?
No. The Shelly 1 Mini Gen3 has no power metering. If you need energy measurement, choose the Shelly 1PM Mini Gen3 version.Does it support Matter or Zigbee?
The Gen3 model runs on 2.4 GHz Wi-Fi and Bluetooth 4.2. It has no Zigbee, Thread or Z-Wave and is not a Matter device as shipped. For native Matter choose a Gen4 model.Can I keep using the physical switch?
Yes. The module has a dedicated SW input, so the existing switch controls the relay in parallel with the app, scenes and voice control.Does it work without internet?
Yes. It supports local control over the Wi-Fi network and MQTT, so it can integrate with a local Home Assistant and be controlled even when the internet is down.
