Welcome to OtaHub
We're excited to announce the launch of OtaHub — a modern, developer-focused platform for managing over-the-air (OTA) firmware updates for IoT devices.
Updating firmware on connected devices should be simple, secure, and reliable. OtaHub helps developers deploy firmware updates, monitor device status, and manage releases without building their own OTA infrastructure.
Why OtaHub?
Managing firmware updates across deployed IoT devices can quickly become complicated. Devices may be distributed across different locations, running different firmware versions, and operating under different network conditions.
OtaHub provides the tools needed to manage the complete firmware update lifecycle:
- Secure OTA updates — Devices authenticate securely before downloading firmware.
- Staged rollouts — Deploy updates gradually using controlled release stages.
- Real-time visibility — Track firmware versions and update activity across devices.
- Reliable firmware delivery — Stream firmware directly to the ESP32 flash partition.
- Developer-first integration — Simple APIs and an Arduino library designed for embedded developers.
Built for ESP32 Developers
OtaHub includes an official Arduino library that makes connecting your ESP32 devices straightforward.
The companion library handles:
- Secure communication with OtaHub servers
- Device provisioning
- Automatic update checks
- Firmware download and flash handling
- Background OTA monitoring without blocking your main application
Your device logic continues running while OtaHub manages updates in the background.
Open Source Arduino Library
The official OtaHub Arduino library is open source and available on GitHub.
You can view the source code, report issues, and contribute:
https://github.com/c-gayan/OtaHub
The library can also be installed directly through the Arduino IDE Library Manager by searching for OtaHub.
What's Next
We're continuing to improve OtaHub with more features for managing large-scale IoT deployments:
- Device grouping — Organize devices by hardware version, location, or custom tags.
- Advanced analytics — Monitor battery status, signal quality, and update performance.
- Webhook integrations — Connect firmware updates with your existing automation workflows.
Whether you're building a small IoT prototype or managing thousands of deployed devices, OtaHub is designed to make firmware updates easier.
