Stable wired Ethernet (LAN8720) — ensures low-latency MQTT publishing and 24/7 uptime.

ESP32 WROVER-IE module — dual-core performance with built-in Wi-Fi, BLE, and 8 MB PSRAM.

Plug-and-play integration — pre-tested with OpenMQTTGateway and ESPHome Bluetooth Proxy.

Rich expandability — 16 GPIO pins, Grove connector, and perf-board area for add-ons.

Visual feedback — four WS2812B LEDs show status and connectivity at a glance.

Built for Makers Reliable, Expandable, and Ready for Home Assistant

Every detail of the ESPGateway Ethernet is designed for stable performance, easy customization, and effortless integration with OpenMQTTGateway or ESPHome.

Built on ESP32 WROVER-IE

The powerful dual-core ESP32 WROVER-IE module combines Wi-Fi, BLE, and 8 MB PSRAM. Perfect for running complex automation scripts, scanning BLE beacons, or acting as a Bluetooth Proxy for Home Assistant.

Open Hardware — Ready to Customize

Full schematics are publicly available, and ThingPulse can help you tailor the ESPGateway hardware to your own requirements or product design.

Maker-Friendly Design

Prototype, extend, and integrate easily. With 16 GPIO pins, a perf-board area, and a Grove connector, you can add sensors, relays, or LoRa E5 modules in minutes — no extra breakout boards required.

Easy Firmware Flashing via USB-C

The onboard CH9102F USB-C interface lets you flash ESPHome, OpenMQTTGateway, or your own firmware without extra adapters. Plug in, program, and you’re ready to bridge BLE to MQTT.

That’s Not All — ESPGateway Ethernet Has Even More to Offer

Every design choice is meant to make integration and experimentation smoother, from expansion options to visual feedback and easy setup.

Grove Connector for Plug-and-Play Expansion

The onboard Grove connector lets you attach Seeed Studio’s LoRa-E5 module or other Grove sensors without soldering. Quickly extend your gateway’s reach — from LoRaWAN coverage to air-quality sensing or motion detection — all plug-and-play.

Customizable User Button

A dedicated push-button on the back of the unit can be freely mapped to your own function — from pairing mode or reset to triggering an automation event in Home Assistant. You decide what it does.

External Antenna for Extended Range

The included 6 dBi external antenna, connected via IPEX, significantly boosts Bluetooth and Wi-Fi coverage — ideal for large homes or sensor networks spread over multiple rooms.

Visual Status LEDs

Four independent WS2812B LEDs show network status, BLE activity, and custom states — making diagnostics simple even without a serial console.

Pick the ESPGateway Setup That Fits Your Project

Whether you’re running a smart home, a BLE sensor network,
or experimenting with LoRa modules — ESPGateway Ethernet adapts to your needs.

Frequently Asked Questions

Everything you need to know about the ESPGateway Ethernet — setup, compatibility, and customization.

Q

Does the ESPGateway support Power over Ethernet (PoE)?

A

No. The ESPGateway uses a standard RJ45 Ethernet interface for networking but requires power via the USB-C port. You can, however, power it from any USB-C adapter or hub supplying 5V.

Q

Can I use it with Home Assistant or OpenMQTTGateway?

A

Absolutely. The ESPGateway is fully compatible with OpenMQTTGateway out of the box and can also run ESPHome as a Bluetooth Proxy. You can publish BLE sensor data directly to Home Assistant without extra configuration.

Q

What’s the Grove connector for?

A

The Grove connector allows you to easily plug in external modules, such as Seeed Studio’s LoRa-E5 for LoRaWAN communication or various Grove sensors (temperature, air-quality, etc.), without soldering.

Q

What does the button on the back do?

A

It’s a user-assignable button. You can map it to your own functions — for example, trigger pairing, toggle a relay, send a custom MQTT message, or start an automation in Home Assistant.

Q

Does the external antenna really make a difference?

A

Yes — the included 6 dBi antenna significantly improves Bluetooth and Wi-Fi range compared to onboard antennas, ensuring more reliable connections even in larger rooms or dense environments.

Q

How do I flash firmware or update it?

A

Connect via USB-C (CH9102F interface) and flash with esptool, ESPHome, or PlatformIO.

Q

What’s included in the box?

A

You’ll receive the ESPGateway Ethernet unit, the external antenna, and the protective enclosure. Bundles optionally include the ePulse Feather low-power board and/or the portable soldering station.

Q

Can I run custom code or my own firmware?

A

Yes! It’s an open development platform based on the ESP32 WROVER-IE, so you can upload your own Arduino or ESP-IDF firmware at any time.
