SMLIGHT SLZB-06M Zigbee 3.0 PoE adapter gets Silabs EFR32MG21 microcontroller

SMLIGHT SLZB-06M is a Zigbee 3.0 to Ethernet, PoE, USB, or WiFi adapter designed to work with multi-vendor software systems such as Zigbee2MQTT and Home Assistant ZHA. This will let you integrate any supported Zigbee devices into smart home automation systems like Home Assistant, OpenHub, or HomeSeer. The SLZB-06M is a variant of the SLZB-06 Zigbee PoE adapter introduced last year with the main difference being the Zigbee chip as the new model is equipped with Silicon Labs EFR32MG21 microcontroller instead of Texas Instruments СС2652Р. An ESP32 WiFi and BLE chip is still used to work with peripherals such as the LAN8720 Ethernet chip and a CP2102N USB/UART converter chip. SMLIGHT SLZB-06M specifications: Wireless SoCs Silicon Labs EFR32MG21 Arm Cortex-M33 microcontroller @ 80 MHz with 352KB flash, 1024KB ROM for protocols and library functions, 96KB SRAM, integrated power amplifier, Bluetooth 5.2 Low Energy and 802.15.4 radios (Zigbee and Thread) Espressif […]

zigpy-zboss library makes Nordic Semi nRF52840 Zigbee dongles compatible with Home Assistant

zigpy-zboss is a Python library that adds support for Nordic Semiconductor nRF52840 modules to zigpy open-source Python Zigbee stack project, as well as other Network Co-Processor radios that run firmware based on ZBOSS Open Initiative (ZOI). This enables integration with compatible Zigbee gateway implementations such as Home Assistant’s ZHA integration component and allows users to directly control Zigbee devices from a wide range of manufacturers such as IKEA, Philips Hue, SmartSung SmartThings, ITEAD SONOFF, Xiaomi Aqara, and others. Home Assistant’s ZHA integration already worked with Zigbee dongles based on Silicon Labs Mighty Gecko EFR32MG21 or Texas Instruments CC2652P microcontrollers, but now it’s possible to use nRF52840 dongles and development as Zigbee Coordinators thanks to the zigpy-zboss library. The zigpy-zboss ZBOSS radio library for zigpy source code and resources can be found on GitHub, but note that this is still an unofficial and experimental port, so testers need to manually […]
