NEWRACOM has just introduced the NRC7394 Wi-Fi HaLow Arm Cortex-M3 SoC with higher power efficiency and lower cost than the previous generation NRC7292 Cortex-M3/M0 HaLow SoC and available in a 6x6mm package. I first wrote about the 802.11ah standard in 2014. Also known as the WiFi HaLow (consumers name), it operates in the 900 MHz band, offers a longer range and lower power consumption for items like IP cameras, and the first products came to market in 2021. I was expecting a flood of new WiFi HaLow devices in 2022 in my year 2021 round-up and it was not exactly a prescient prediction as it never happened. But maybe the new NRC7394 SoC will help make WiFi HaLow devices more popular by lowering the costs and further improving battery life. NEWRACOM NRC7394 key features: CPU – Arm Cortex-M3 core @ 32 MHz for IEEE 802.11ah WLAN and application Connectivity Full […]
Zvidar Z-GW-V01 Smart Gateway runs Home Assistant on Allwinner A133 processor
Shenzhen Zvidar Technologies’ Z-GW-V01, also known as the Zvidar Smart Gateway is a single board computer powered by an Allwinner A133 quad-core Cortex-A53 processor and running Ubuntu with the Home Assistant open-source automation framework. The SBC provides Gigabit Ethernet, WiFi 5, and Bluetooth connectivity by default, but also supports plenty of optional wireless modules with Z-Wave, Zigbee, Thread/Matter, LoRa, or 4G LTE connectivity that are either soldered to the board connected by a mini PCIe socket. The board also includes a few USB ports, and it’s apparently possible to connect a 7-inch display and/or audio interfaces if needed. Zvidar Smart Gateway (Z-GW-V01) specifications: SoC – Allwinner A133 quad-core Cortex-A53 processor @ up to 1.6GHz with Imagination PowerVR GE8300 GPU with support for OpenGL ES3.2, Vulkan 1.1, OpenCL 1.2 System Memory – 1GB RAM (option for 512MB, 2GB, or 4GB) Storage – 8GB eMMC flash (option for 4GB, 16GB, or 32GB), […]
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. […]
