This comparison evaluates the main product Shelly LoRa Add-on alongside several alternative devices from the Shelly brand, including Shelly EM Gen3, Shelly Pro 1, Shelly RC Snubber, and the wireless button modules Shelly Button Add-on (BaoB) and Shelly Button Add-on (BaoW). All selected items belong to the Shelly ecosystem but serve entirely different functions: the main product is designed for adding long-range LoRa wireless connectivity to sensors and remote nodes, whereas the alternatives focus on energy measurement, load switching, voltage spike protection, or physical button control.
⚙️ Below is a comparison of technical features and functional purposes, highlighting key connectivity options and practical use cases.
| Comparison parameter | Shelly LoRa Add-on | Shelly EM Gen3 | Shelly Pro 1 | Shelly RC Snubber | Shelly Button Add-on (BaoB) | Shelly Button Add-on (BaoW) | Practical significance |
|---|
| Device type | LoRa wireless communication module | Energy measurement controller | Solid-state relay | RC snubber filter module | Wireless button interface (black) | Wireless button interface (white) | The products have entirely different purposes and do not compete directly, instead addressing different smart home requirements. |
| Core technology | LoRa protocol for long-range communication | Wi-Fi connectivity for energy monitoring | Wi-Fi connectivity for load switching | AC voltage spike and surge protection | Physical button integration (black) | Physical button integration (white) | The main product provides long-range coverage for remote sensors, while other models address local control, power switching, and protection. |
| Application area | Sensor networks and remote monitoring | Electrical energy tracking and diagnostics | Switching of electrical loads up to 16A | Stabilization of 230V AC circuits | Manual scene control (black enclosure) | Manual scene control (white enclosure) | Selection depends entirely on the engineering task: from long-range communication to power control or local physical input. |
◎ The table below evaluates how well each product matches specific user needs and usage scenarios to help identify the best choice.
| Use case | Recommended product | Why |
|---|
| Establishing long-range wireless communication for sensors | Shelly LoRa Add-on | Specifically built to extend coverage and enable low-power, long-range communication using the LoRa protocol in distributed networks. |
| Monitoring electrical consumption and energy tracking | Shelly EM Gen3 | Equipped for real-time electrical measurement and reporting to help optimize residential or commercial energy usage. |
| Automating and switching heavy electrical loads safely | Shelly Pro 1 | Rated for loads up to 16A at 110-240V, designed for professional installation and automated appliance control. |
| Protecting equipment from voltage spikes and ensuring stable operation | Shelly RC Snubber | Designed for 230V AC circuits to protect sensitive devices from voltage spikes and maintain stable electrical operation. |
| Local manual control of lighting or scenes (black version) | Shelly Button Add-on (BaoB) | Provides a compact physical control point for triggering automations quickly without relying on the app. |
| Local manual control of lighting or scenes (white version) | Shelly Button Add-on (BaoW) | Offers the same wireless button control functionality in a white enclosure for seamless interior placement. |
Recommendation: Shelly LoRa Add-on is best suited for projects requiring extended range and low-power IoT communication via LoRa in sensor networks or remote monitoring setups where standard Wi-Fi is impractical. If your project involves energy monitoring, heavy load switching, circuit protection, or physical button controls, select the specialized alternative Shelly device that matches your specific operational requirement.
