FAQ

What are the differences between the different generations of Shelly products?

Each new generation adds more power, memory, and features:

Gen 1 offers basic control;

Gen 2 (Plus Series, Mini Series, Pro Series) adds Bluetooth, scripting, and better security;

Gen 3 improves performance, adds Matter (starting from firmware version 1.6.0 or newer) and advanced monitoring;

Gen 4 offers multi-protocol connectivity, featuring Wi-Fi 6, Bluetooth, Zigbee, and Matter.

Learn more: https://support.shelly.cloud/en/support/solutions/articles/103000316073-comparison-of-shelly-gen-1-gen-2-and-gen-3-devices?fbclid=IwY2xjawJHTR9leHRuA2FlbQIxMAABHaBfrCc1-eqoghqxTVUgn7QBaaqTBKa_dZyem_FbH6z6WrlrHbWo0p_OTg_aem_ltK1ZvtsjkrpzXAFx7uvhQ

Can I control the device via Bluetooth?

No, the protocol is used only for device inclusion, allowing for quick and easy setup through the Shelly Smart Control app.

For bluetooth control it is required to have another Bluetooth device such as Shelly BLU Button or Shelly BLU Motion to interact.

Additionally, Shelly devices can function as a BLE gateway, bridging Shelly BLU devices to your Wi-Fi network.

Does this device support Matter protocol?

Yes, it supports the Matter protocol starting from firmware version 1.6.0 or newer. This enables seamless integration with Matter-compatible smart home ecosystem.

What does "dry contact" mean?

Dry contacts (also called potential-free contacts) are relay contacts that are completely isolated from the device's own power supply. Here's what this means:

Regular relay contacts: The switch contacts are connected to the device's internal power circuits

Dry contacts: The switch contacts are completely separate - like a mechanical switch with no electrical connection to the device itself

Why this matters for you:

- You can switch any voltage through the contacts (within rating limits)

- The contacts can break both live AND neutral lines safely

- No risk of electrical interference between your load circuit and the device's control circuit

- Perfect for true 2-pole switching applications

What is the maximum load capacity of the device?

The device supports: Up to 16A for resistive loads (e.g., incandescent bulbs, heating devices). For inductive or capacitive loads (e.g., motors, LED drivers), it's recommended to use an RC snubber to prevent potential issues.

Can I use the device without an internet connection?

Yes, the device can operate solely on a local Wi-Fi network. You can control it via its embedded web interface or through local integrations like MQTT. Internet connectivity is only required for remote access or cloud-based features.

Does the device support MQTT for integration with home automation systems?

Yes, the device supports MQTT, enabling seamless integration with home automation platforms like Home Assistant. You can configure MQTT settings through the device's web interface.

Is it possible to use the device without a hub?

Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.

Great product! It was easy to connect it to the garage motor and the setup on Shelly app was smooth

Great product! It was easy to connect it to the garage motor and the setup on Shelly app was smooth. Everything worked as expected from the first trial. Easy to control the garage door remotely. Also connecting Shelly app with Google home automation was very easy.

The only downside is that Shelly widget on Android is broken. The button widget doesn't really work.

Very happy with switch

Very happy with switch - though had to order a second as couldn't get the first one to work. And the instructions were poor, scarcely mentioning the location and colour of the light.

Super!!

I purchased the Shelly Gen3 to replace the Gen1 series that I've had for over 6 years

I purchased the Shelly Gen3 to replace the Gen1 series that I've had for over 6 years. I can say I was one of the first to trust Shelly for my home automation. Regarding the Shelly 1, I've never had any problems in all these years. From initial impressions, the new ones seem much more responsive than the previous ones. I hope they're as reliable as the previous ones. TOP SHELLY!!

Great product, easy to instal and program.

very good and reliable

The wifi switches are very good and reliable. Before I had a different wifi switch and after an outage of the wifi they were on by default which has caused me a lot of problems. But the Shelly don't have this problem. They are very reliable and don't turn on after the wifi was off for a while.
I use this wifi switch to clean my life webcams on top of my hotels in Blackpool remotely with a cleaning nozzle and a water pump. See my webcam here: https://www.granadaapartments.uk/live-cameras

Shelly 1’s are super versatile in-home automation projects I like to keep on handy for my next idea

Shelly 1’s are super versatile in-home automation projects I like to keep on handy for my next idea. I have 12 Shelly 1's of all generation; they just keep getting better. In the three years I have been using them they have proven very reliable and tend to be my start point for most of my projects.
I only have one downer on them and that is they don’t work for me as Bluetooth Proxy, I have to use STACK ESPHome for that task.
