Other Matter-compatible ecosystems<\/li>\n<\/ul>\nThis makes the Gen4 a strong choice for customers who want flexibility rather than being locked into a single smart home platform.<\/p>\n
\nExcellent for Home Assistant<\/h2>\n
The Shelly 1PM Gen4 is particularly well suited to Home Assistant.<\/p>\n
Combine switching and energy measurements to create sophisticated local automations and energy dashboards.<\/p>\n
For example:<\/p>\n
Smart Geyser Automation<\/h3>\n
Monitor geyser power consumption and automatically control heating based on schedules, electricity tariffs or solar availability.<\/p>\n
Appliance Monitoring<\/h3>\n
Track the electricity usage of individual appliances without installing a full-house energy monitor.<\/p>\n
Solar Automation<\/h3>\n
Use power measurements as triggers for automations based on available solar generation.<\/p>\n
Smart Lighting<\/h3>\n
Automatically switch lights based on occupancy, time of day or other sensors.<\/p>\n
\nNo Hub Required for Wi-Fi<\/h2>\n
For Wi-Fi installations, the Shelly 1PM Gen4 connects directly to your local network.<\/p>\n
You can control it using the Shelly Smart Control app, local network interfaces, supported smart home platforms or cloud services.<\/p>\n
No dedicated hub is required for standard Wi-Fi operation.<\/p>\n
This makes it easy to add smart control and energy monitoring to an existing home.<\/p>\n
\nCompact Retrofit Design<\/h2>\n
The Shelly 1PM Gen4 measures only:<\/p>\n
37 \u00d7 42 \u00d7 16 mm<\/strong><\/p>\nIts compact enclosure allows it to fit into many existing electrical installations, including suitable wall boxes and spaces behind switches and sockets.<\/p>\n
This makes it particularly useful for smart home retrofits, where replacing existing switches or installing additional equipment may not be desirable.<\/p>\n
\nAdvanced Energy & Safety Features<\/h2>\n
The Shelly 1PM Gen4 provides more than simple remote switching.<\/p>\n
Built-in protection features include:<\/p>\n
\n- Overtemperature protection<\/li>\n
- Overvoltage protection<\/li>\n
- Overcurrent protection<\/li>\n
- Overpower protection<\/li>\n<\/ul>\n
You can also configure automation and protection thresholds based on measured electrical parameters.<\/p>\n
This provides greater control over both your devices and their energy consumption.<\/p>\n
\nAdvanced Smart Automation<\/h2>\n
For advanced users, the Shelly 1PM Gen4 provides extensive automation capabilities.<\/p>\n
Features include:<\/p>\n
\n- Schedules<\/li>\n
- Smart scenes<\/li>\n
- Local actions<\/li>\n
- Webhooks<\/li>\n
- MQTT<\/li>\n
- WebSockets<\/li>\n
- HTTPS<\/li>\n
- mJS scripting<\/li>\n
- KNXnet\/IP<\/li>\n
- Virtual components<\/li>\n<\/ul>\n
This makes it suitable for everything from simple scheduled lighting to sophisticated Home Assistant energy management systems.<\/p>\n
\nZigbee Router & Bluetooth Gateway<\/h2>\n
The Shelly 1PM Gen4 can also contribute to your wider smart home network.<\/p>\n
When used with the appropriate protocols, it can function as:<\/p>\n
\n- Zigbee router<\/strong> \u2013 helping extend your Zigbee mesh<\/li>\n
- Bluetooth gateway<\/strong> \u2013 connecting compatible Bluetooth devices<\/li>\n<\/ul>\n
This means a single installed relay can provide additional value beyond controlling its connected load.<\/p>\n
