I recently came across some exciting developments regarding the use of Nordic Semiconductor’s nRF52840 dongle as a Zigbee Coordinator for Home Assistant’s ZHA integration. This opens up new possibilities for those looking to expand their smart home setups without breaking the bank. The nRF52840 dongle, priced around $10, is a cost-effective solution that leverages the ZBOSS Zigbee stack, which is both open-source and hardware-independent. This compatibility makes it a versatile option for integrating various Zigbee devices into a Home Assistant ecosystem.
The potential to use ESP32-C6 and ESP32-H2 SoCs with ESPHome as Zigbee adapters is equally intriguing. These chips support 802.15.4, Zigbee, and Thread, making them ideal for a wide range of applications. The ESP32-C6, in particular, is a promising candidate for future integrations, offering WiFi 6 and Bluetooth 5.0 support alongside its Zigbee capabilities. This could pave the way for more efficient and versatile smart home solutions.
For those interested in experimenting with these technologies, the zigpy-zboss library provides a framework for utilizing the nRF52840 dongle as a Zigbee Coordinator. Although still in its experimental stages, this library allows users to manually add the radio library to ZHA, enabling a bleeding-edge integration. The ESP32-C6 and ESP32-H2 support is currently under development, with the hope that it will soon offer a seamless experience for both new and existing users of ESPHome.
This development is particularly exciting for those who value open-source solutions and are looking to push the boundaries of their smart home setups. It not only enhances the flexibility of existing integrations but also opens doors for future innovations in home automation. If you’re eager to explore these possibilities, I encourage you to check out the zigpy-zboss library and stay updated on the latest developments in ESP32 support for Zigbee. Happy experimenting!
