Notificator devices
Give important alerts a place in the physical world.
Build a compact display for selected website events using compatible ESP32 hardware, open-source Notificator firmware, and MQTT delivery.
Notificator Base A dedicated signal
Some alerts deserve more than another browser tab.
A Notificator device can keep a selected event visible without requiring the WordPress dashboard or your phone to remain open.
Use a lightweight channel designed for connected clients.
Use your own HiveMQ Cloud cluster, isolate credentials for each client, and rotate or revoke them without storing the broker password in your Notificator account.
Build with accessible ESP32 hardware and adaptable firmware.
Choose a model
A compact Base and a touchscreen preview.
Each model has its own hardware target and release channel, while sharing the same Notificator account, MQTT topics, and signed update system.
Notificator Base
Stable firmware 1.2.2 for an ESP32-C3 SuperMini, SSD1306 OLED, and TTP223 capacitive control.
Notificator Touch
Preview firmware 0.9.3 for the Waveshare ESP32-S3 Touch LCD 3.49, with audio, clock, weather, and alert history.
More tested hardware over time.
Matter and other models remain future targets. Each supported board receives its own firmware identity and update channel, so packages cannot cross between incompatible devices.
Follow firmware updates →Build path
From WordPress event to physical display.
The device is one optional destination in the wider Notificator workflow.
- 01
Choose compatible hardware
Start with a supported ESP32 board, display, and the components described by the firmware project.
- 02
Install the firmware
Choose a compatible release and flash the complete firmware over USB with the browser installer.
- 03
Connect through MQTT
Link the device to your Notificator account and route selected WordPress notifications to its MQTT channel.
- 04
Make it your own
Experiment with screens, enclosures, alert layouts, and physical outputs while respecting third-party asset licenses.
Open-source foundation
Inspect it, build it, and adapt it.
The Notificator device firmware is published openly so makers and developers can understand how it works, build compatible hardware, and contribute improvements.
- Open-source firmware
- Compatible ESP32 hardware
- MQTT-based notification delivery
- Room for custom displays and outputs
Community batches
Cannot build one? You may still get one.
Notificator devices were introduced publicly at WordCamp Athens 2025, where the first devices were shared with attendees. We plan to keep making occasional small batches and send ready-to-use devices free of charge to randomly selected people in the community.
Each device is printed, assembled, flashed, and tested before it leaves us.
The devices are not sold. Selected recipients receive their device at no charge.
Quantities are limited, and recipients are selected randomly according to the details announced for each batch.
How will I know when a batch is available?
Follow project updates. Every opportunity will explain its timing, availability, selection process, and any location restrictions before entries open.
Enclosure attribution
Open firmware and separately licensed enclosure files.
The enclosure shown by Notificator is based on the TinyTosh Mini Retro PC by Uladzimir Hitsarau. The model is licensed separately under the MakerWorld Standard Digital File License and is not redistributed by this project.
