๐Ÿ“Œ Overview

ESPresense is an open-source project that uses ESP32-based BLE scanning technology to detect the presence and indoor location of people or devices. Multiple nodes are placed throughout an indoor space to collect signals transmitted from smartphones, smartwatches, and BLE tags, and these signals are integrated with a server or Home Assistant via MQTT, enabling room-level occupancy detection or precise indoor location estimation.

The core concept of this project is not simply collecting BLE signals, but designing the system so that the data can be connected to real automation and spatial awareness services. Users can identify which room a specific person is in, or automatically control lighting, HVAC, notifications, and security functions based on whether someone enters or leaves a space.

๐Ÿ“Œ Features

Room-Level Occupancy Detection

The system determines which room a user is in based on the nearest ESPresense node. It can be integrated with Home Assistantโ€™s mqtt_room to automate lighting, notifications, and HVAC systems.

Precise Indoor Position Estimation

Multiple nodes simultaneously collect distance information, and the Companion aggregates this data to calculate X,Y coordinates. This allows the system to extend beyond simple โ€œroom detectionโ€ to position estimation within a floor.

MQTT-Based System Integration

Node status, device detection results, and telemetry data are transmitted via MQTT, and Home Assistant MQTT Discovery is also supported. As a result, the integration process after installation is relatively simple.

BLE Fingerprint / Apple IRK Support

The official site emphasizes fingerprint-based IDs and Apple IRK registration instead of MAC addresses. This improves the reliability of actual user identification compared to simple BLE scanning.

Wired Ethernet Expansion Possibility

Public PR #2178 includes support for W5500 SPI Ethernet on the Waveshare ESP32-S3-ETH, dynamic Ethernet board selection in the UI, and expansion of the ESP32-S3 network layer. This provides a technical foundation for converting wireless-only nodes into wired industrial nodes.

๐Ÿ“Œ System Architecture

Overall Architecture

When BLE tags, smartphones, or smartwatches transmit advertising signals, they are received by ESPresense nodes (ESP32-based devices) installed in each room or zone.

Each node then sends RSSI or distance estimation data to an MQTT broker, and an upper-level system such as Home Assistant or the ESPresense Companion consumes this data to calculate room-level presence status or coordinate-based location information.

Data Flow

  • BLE device transmission
  • ESPresense node reception
  • Node publishes data to the network via MQTT
  • Home Assistant / Companion subscribes to the data
  • Applied to automation, dashboards, and location calculation

๐Ÿ“Œ Role and Application of the WIZnet's Chip

WIZnet Chip Used: W5500

In the public GitHub Issue #1955 and PR #2178, the request and implementation for Waveshare ESP32-S3-ETH with W5500 Ethernet support are clearly described.

Role in the network

  • In this project, the W5500 functions as the wired network interface for BLE scanning nodes.
  • Communication with upper systems is structurally centered on MQTT, which is used to transmit node status, device detection results, and telemetry data.
    The official Home Assistant integration documentation also explains a configuration based on MQTT topics.

๐Ÿ“Œ Market & Application Value

Applicable Markets

  • Smart Home / Home Automation
    • It can be directly connected to automation based on indoor movement, such as lighting, HVAC, entry notifications, and indoor activity patterns. The official documentation also presents room-based automation and precise positioning as key use cases.
  • Smart Offices / Meeting Rooms / Visitor Flow Analysis
    • It can be extended to a structure that identifies zone-level occupancy using BLE tags or internal devices, without excessively infringing on personal privacy. This is an interpretation of potential applications based on the publicly available system architecture.
  • Lightweight RTLS (Real-Time Location System)
    • Compared to expensive UWB-based systems, it enables room-level or semi-precise indoor positioning at a lower cost. Therefore, it is suitable for applications such as asset tracking, occupancy-based energy savings, and zone-triggered events.

External Response Based on Issues/PRs

https://github.com/ESPresense/ESPresense/issues/1955

https://github.com/ESPresense/ESPresense/pull/2178/commits

  • In Issue #1955, a user requested support for the Waveshare ESP32-S3-ETH W5500, stating that it does not work with the existing Ethernet type option. This indicates that there is publicly visible demand from users attempting to apply W5500-based boards to ESPresense.
  • Following this, PR #2178 proposed W5500 SPI Ethernet support, dynamic Ethernet option selection in the UI, and expansion of the ESP32-S3 network layer. In other words, the request progressed from user demand to an implementation attempt.

๐Ÿ“Œ Summary

This UCC is meaningful in that it demonstrates the Ethernet expansion potential using the WIZnet W5500 based on the publicly available ESPresense open-source project. The project itself aims at BLE-based indoor presence detection and location estimation, and it is structured to be integrated with platforms such as Home Assistant, enabling a variety of automation scenarios in real environments.

In particular, the fact that requests for W5500-based Ethernet support and implementation attempts can be observed in the public community shows that WIZnet chips can expand beyond typical embedded network connectivity into areas such as indoor positioning, spatial automation, and low-cost IoT infrastructure. From a Maker perspective, this can be interpreted as a case that goes beyond a simple demonstration and presents real application potential and external scalability.

From the viewpoint of introducing this case on the Maker website, it serves as a good reference demonstrating โ€œhow WIZnet chips can be used within new system architectures.โ€ Furthermore, the application scope could be expanded in the future to areas such as smart homes, smart offices, lightweight asset tracking, and occupancy-based automation devices, making this project meaningful in terms of expanding the WIZnet ecosystem as well.

๐Ÿ“Œ FAQ

Q1. What is the ESPresense project?

ESPresense is an open-source system that uses ESP32-based BLE scanning technology to detect the presence and location of people or devices indoors. By placing multiple ESPresense nodes in a space, signals from smartphones, smartwatches, and BLE tags can be collected and transmitted via MQTT. Home Assistant or a Companion system then analyzes the data to provide room-level occupancy detection and indoor position estimation.

Q2. How does ESPresense estimate indoor location?

ESPresense collects BLE advertisement signals transmitted by BLE devices, which are received simultaneously by multiple ESP32 nodes. Each node measures RSSI-based distance estimates, and this data is sent to a server via MQTT. The upper-level system then combines data from multiple nodes to calculate the userโ€™s location or room-level occupancy status.

Q3. How does ESPresense integrate with Home Assistant?

ESPresense uses an MQTT-based communication architecture, making it easy to integrate with Home Assistant. Device information and status data detected by nodes are transmitted through MQTT topics, and Home Assistant automatically registers them using MQTT Discovery. This enables various smart home automations such as lighting, HVAC, and notification control.

Q4. What role does the WIZnet W5500 chip play in ESPresense?

The WIZnet W5500 acts as a wired Ethernet network interface in ESPresense nodes. It provides a stable Ethernet connection so that device detection data and node status information collected by the BLE scanning node can be reliably transmitted to the MQTT broker.

Q5. Why is Ethernet support needed in ESPresense?

Although ESPresense nodes typically use Wi-Fi, Ethernet can provide better network stability and lower latency. In environments such as smart home hubs, server rooms, or industrial spaces, wired networks are often more reliable than Wi-Fi, making W5500-based Ethernet expansion beneficial.
