Energy consumption<\/li>\n<\/ul>\nUse this information to identify energy-hungry appliances, track usage patterns and create smarter automation based on actual power consumption.<\/p>\n
For example, you can create automations that respond when a device starts or stops consuming power, making the Shelly 1PM Gen3 particularly useful for geyser monitoring, appliance monitoring and energy-management projects.<\/p>\n
\ud83d\udd0c Powerful 16A Smart Relay<\/h3>\n
The Shelly 1PM Gen3 can switch loads of up to 16A at 240V AC<\/strong>, making it suitable for many household and commercial applications.<\/p>\nIdeal for controlling:<\/p>\n
\n- Lights<\/li>\n
- Fans<\/li>\n
- Geysers<\/li>\n
- Heaters<\/li>\n
- Pumps<\/li>\n
- Floor heating<\/li>\n
- Appliances<\/li>\n
- Water heating systems<\/li>\n
- Other suitable electrical loads<\/li>\n<\/ul>\n
The device also supports DC applications within its specified ratings.<\/p>\n
\ud83d\udee1\ufe0f Built-In Power Protection<\/h3>\n
The Shelly 1PM Gen3 continuously monitors the electrical conditions of the connected circuit and provides configurable protection features.<\/p>\n
Protection includes:<\/p>\n
\n- Overpower protection<\/li>\n
- Overcurrent protection<\/li>\n
- Overvoltage protection<\/li>\n
- Overtemperature protection<\/li>\n<\/ul>\n
Set appropriate limits and allow the Shelly to automatically disconnect the load if configured thresholds are exceeded.<\/p>\n
This provides an additional layer of protection while also making the device useful for energy management and load monitoring.<\/p>\n
\ud83c\udf10 Wi-Fi \u2013 No Hub Required<\/h3>\n
Unlike Zigbee devices, the Shelly 1PM Gen3 connects directly to your existing 2.4GHz Wi-Fi network<\/strong>.<\/p>\nNo dedicated Shelly hub is required.<\/p>\n
Use the Shelly Smart Control app, web interface or your preferred smart-home platform to control and monitor the device.<\/p>\n
The relay can also provide local control, allowing automation to continue operating within your network without every command needing to rely on an external cloud service.<\/p>\n
\ud83c\udfe0 Matter Ready<\/h3>\n
The Shelly 1PM Gen3 can be upgraded with compatible firmware to support Matter<\/strong>, making it easier to integrate the device into modern multi-platform smart homes.<\/p>\nMatter integration allows compatible smart-home platforms to discover and control supported Shelly devices, helping reduce dependence on a single manufacturer’s ecosystem.<\/p>\n
Compatible platforms can include:<\/p>\n
\n- Apple Home<\/li>\n
- Google Home<\/li>\n
- Amazon Alexa<\/li>\n
- Samsung SmartThings<\/li>\n
- Home Assistant<\/li>\n
- Other Matter-compatible systems<\/li>\n<\/ul>\n
Matter functionality depends on the installed firmware and supported features of the Matter platform.<\/strong><\/p>\n\ud83e\udde0 Powerful Gen3 Hardware<\/h3>\n
The Shelly 1PM Gen3 is built around Shelly’s updated Gen3 hardware platform, featuring the ESP-Shelly-C38F processor and 8MB of flash memory.<\/p>\n
This provides improved processing capacity for advanced automations, scripting and future firmware functionality.<\/p>\n
\ud83d\udcf6 Wi-Fi + Bluetooth<\/h3>\n
The Shelly 1PM Gen3 includes both Wi-Fi and Bluetooth 4.2<\/strong>.<\/p>\nBluetooth allows convenient device setup and can also be used as a gateway for compatible Shelly BLU devices.<\/p>\n
The device also supports Wi-Fi range-extender functionality for supported applications.<\/p>\n
\ud83e\udd16 Advanced Automation<\/h3>\n
The Shelly 1PM Gen3 isn’t limited to simple on\/off control.<\/p>\n
Create sophisticated automations using:<\/p>\n
\n- Schedules<\/li>\n
- Timers<\/li>\n
- Scenes<\/li>\n
- Local actions<\/li>\n
- Webhooks<\/li>\n
- MQTT<\/li>\n
- HTTP\/HTTPS<\/li>\n
- WebSockets<\/li>\n
- UDP<\/li>\n
- TLS<\/li>\n
- mJS scripting<\/li>\n
- KNXnet\/IP<\/li>\n<\/ul>\n
This makes it suitable for everything from simple smart lighting to advanced Home Assistant and DIY automation projects.<\/p>\n
\ud83d\udcca Energy Monitoring for Smarter Homes<\/h3>\n
One of the biggest advantages of the Shelly 1PM Gen3 is the ability to combine switching with energy data.<\/p>\n
Instead of simply asking:<\/p>\n
\n“Is the device on?”<\/p>\n<\/blockquote>\n
you can also determine:<\/p>\n
\n“How much power is it using?”<\/p>\n<\/blockquote>\n
This opens up possibilities such as:<\/p>\n
\n- Monitoring geyser electricity consumption<\/li>\n
- Tracking appliance energy usage<\/li>\n
- Identifying standby consumption<\/li>\n
- Automatically switching loads based on consumption<\/li>\n
- Creating energy-saving schedules<\/li>\n
- Monitoring heating systems<\/li>\n
- Tracking individual circuits<\/li>\n
- Integrating consumption data into Home Assistant<\/li>\n<\/ul>\n
For customers building an energy-conscious smart home, this makes the Shelly 1PM Gen3 considerably more useful than a conventional smart switch.<\/p>\n
\nIdeal Applications<\/h2>\n\ud83d\udca1 Smart Lighting<\/h3>\n
Automate lights with schedules, scenes, timers and occupancy-based automation while monitoring their energy consumption.<\/p>\n
\ud83d\udebf Geyser & Water Heating Monitoring<\/h3>\n
Monitor the power consumption of a geyser or water-heating circuit and use the data to optimise heating schedules and reduce unnecessary electricity usage.<\/p>\n
\ud83d\udd25 Heaters & Floor Heating<\/h3>\n
Control electric heaters and suitable heating circuits while monitoring how much energy they consume.<\/p>\n
\ud83c\udfe0 Appliance Monitoring<\/h3>\n
Track the electricity consumption of appliances such as washing machines, dishwashers, fridges and other suitable loads.<\/p>\n
\ud83d\udca7 Pumps<\/h3>\n
Automate and monitor suitable water, irrigation and circulation pumps.<\/p>\n
\ud83c\udfe1 Home Assistant & DIY Automation<\/h3>\n
The Shelly 1PM Gen3 is an excellent choice for advanced users who want local APIs, MQTT, scripting and detailed energy data for custom automation.<\/p>\n
\nCompact Retrofit Design<\/h2>\n
Despite its advanced capabilities, the Shelly 1PM Gen3 measures just:<\/p>\n
37 \u00d7 42 \u00d7 16 mm<\/strong><\/p>\nIts compact design allows it to fit behind many existing wall switches, sockets and electrical equipment, making it an excellent choice for smart-home retrofits where installation space is limited.<\/strong><\/p>\n
