Silicon Labs partners with Nabu Casa to support Home Assistant development

Silicon Labs has entered an official partnership with Nabu Casa, the company behind the popular Home Assistant home automation software, to support the development of Home Assistant open-source software and Silicon Labs-based hardware platforms. Most open-source embedded software projects start as a one-person (or a small team) effort as the vendor-provided firmware and related software may not have the features set needed by this user or group of users. So they hack existing hardware to build something that better fits their requirements often without input/help from the silicon vendor or product manufacturer. But sometimes the project becomes popular enough that large companies start to help it with support and funding. That’s apparently the case for Home Assistant project with Silicon Lans and Nabu Case entering an official partnership. The announcement does not provide details about the partnership but explains this should lead to better support and improvements for both Home […]

Review of RaZberry 7 Pro Z-Wave Raspberry Pi HAT and Z-Uno2 Z-Wave board

Z-Wave.Me has sent us a couple of Smart Home devices based on Z-Wave technology for review, namely the RaZberry 7 Pro Raspberry Pi HAT and the Z-Uno2 board. The Swiss company has primarily developed Z-Wave products for years and is a member of the Z-Wave Alliance. For those who are concerned about the issues of signal interference in the 2.4GHz range (WiFi, Zigbee, Bluetooth, and Thread), Z-Wave technology is an excellent choice because it operates on a less congested frequency range of 800-900MHz and the technology has been around for more than 20 years, resulting in a wide variety of Z-Wave devices available in the market, and they can work well together across different brands due to a proper certification process which is another advantage when compared to other protocols. The two devices we received are RaZberry 7 Pro, which is a shield that plugs into the 40-pin GPIO header […]

SONOFF SNZB-06P Zigbee human presence sensor is based on a 5.8GHz microwave radar

SONOFF SNZB-06B human presence detection sensor

ITEAD has launched a new Zigbee sensor with the SONOFF SNZB-06P designed to detect human presence using a 5.8GHz microwave radar whose main advantage over a traditional PIR motion sensor is the ability to detect stationary persons since this type of sensor can detect breathing. You’ll need a Zigbee Hub from SONOFF such as the NSPanel Pro or SONOFF iHost, or from other manufacturers, for instance, the Amazon Echo Plus 2nd generation, or simply use a Zigbee USB dongle such as the SONOFF ZBDongle-E connected to a host like a Raspberry Pi. Configuration and control is done through the usual eWelink app for Android or iOS. SONOFF SNZB-06P specifications: MCU – Silicon Labs EFR32MG22 wireless microcontroller Human presence sensor 5.8GHz microwave radar Sensitivity configurable from 2.5 meters to 4 meters Wireless – Zigbee 3.0 (router type) up to 30 meters Misc – Red LED, magnetic base, button Power Supply – […]

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 […]
