Replacing a classic double wall switch, the SONOFF NSPanel EU combines two 230V relays, a 3.5-inch TFT touch screen (480 × 320 px), an integrated temperature sensor, and 2.4 GHz Wi-Fi connectivity in a compact 86 × 86 × 41.7 mm format. It requires phase + neutral wiring to operate and allows centralizing lighting control, home automation scenes, and temperature from a single wall screen, without multiplying devices.

Real-time display, dual physical and touch control

The NSPanel screen constantly displays the time, date, outdoor weather, and ambient temperature measured by its integrated sensor. The two physical buttons directly control the connected electrical circuits, while the touch screen provides quick access to devices, groups, and scenes configured in the eWeLink app. These two control modes work simultaneously and independently to ensure simple control for all household members.

Smart heating management and automations

Thanks to its integrated temperature sensor, the NSPanel can automate heating by directly controlling 230V-powered equipment, such as certain solenoid valves or electric radiators. To control a boiler with a dry contact (potential-free) input, a suitable relay module or automation via other compatible equipment is necessary. Smart scenes then allow automatically maintaining the desired temperature and triggering personalized routines based on schedules or measured conditions.

Home automation integration and advanced customization

The NSPanel operates directly on 2.4 GHz Wi-Fi without an additional gateway and integrates naturally into the eWeLink ecosystem. It is compatible with Amazon Alexa, Google Assistant, and Siri via eWeLink shortcuts. Thanks to its architecture based on an ESP32 chip, it is also very popular with Home Assistant users. It can be used with various community projects, particularly under ESPHome, to benefit from a fully customizable touch interface and advanced local operation.

Scheduled programming and voice control

Schedules, countdowns, and scenarios are configured from the eWeLink app to automate lighting and equipment according to household habits. Voice commands via Alexa or Google Assistant allow contactless control of devices, while smart scenes facilitate the synchronization of multiple pieces of equipment in a single action.

FAQ

Can the NSPanel EU directly control a boiler?

Not directly in most installations. The two integrated relays of the NSPanel deliver a 230 V AC voltage. If your boiler requires a dry contact (potential-free) input, it is essential to use a suitable relay or module between the NSPanel and the boiler. Always check the electrical characteristics of your installation before connection.

Does the NSPanel EU require a home automation gateway?

No. The NSPanel integrates its own 2.4 GHz Wi-Fi connectivity and connects directly to your network to work with the eWeLink app as well as with compatible voice assistants. No SONOFF hub is necessary.

Is the NSPanel compatible with Home Assistant?

Yes. Thanks to its ESP32 chip, the NSPanel is widely supported by the Home Assistant community. It can be used with various ESPHome-based projects to create a custom touch interface and fully local operation. However, these customizations rely on community projects and are not officially supported by SONOFF.

Can the NSPanel screen be customized?

Yes. With the original firmware, the screen displays devices, scenes, and information available in eWeLink. Advanced users can also fully customize the interface via ESPHome-based community projects.
