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 […]

SONOFF TX Ultimate Review – A smart touch wall switch with innovative features

SONOFF has been producing a wide range of new products over the years, and since the beginning of the year, the company introduced various new products and features including the iHost Smart Home Hub local hub which no longer requires cloud connectivity. The one we are going to review is the Ultimate Smart Touch Wall Switch (also known as the SONOFF TX Ultimate). SONOFF stated that they wanted to provide a new experience with their smart switch. Initially, we couldn’t imagine what new experiences a smart switch could offer. When we think of SONOFF, we usually associate it with affordable smart switches that are durable and perform as expected, not stylish or feature-rich devices. However, the SONOFF TX Ultimate comes as a complete package with light, color, sound, and touch. SONOFF has also expanded the touch area, so there’s no need to worry about missing the button while pressing it. […]
