Zigbee Firmware News – TI Z-Stack 3.0 Zigbee for CC2530 & ptvo Zigbee FW Configuration Tool

We’ve been writing about Zigbee more in recent months with either product announcements such as Sonoff ZBBridge WiFi to Zigbee gateway, and open-source software updates such as Tasmota support for Zigbee connectivity. We’ve recently been tipped about Zigbee-related news, namely TI Z-Stack 3.0 Zigbee router firmware port to Sonoff BASICZBR3, and ptvo Zigbee Configurable Firmware v2.4 GUI tool designed to create alternative Zigbee switch and router firmware for TI CC253x based modules and devices TI Z-Stack 3.0 Zigbee Router Firmware on Sonoff BASICZBR3 Kirovilya, a well-known open-source developer and founder of ioBroker open-source home automation software, has ported TI Z-Stack 3.0 Zigbee router firmware to CC2530 and tested it on Sonoff BASICZBR3 with DS18B20 waterproof temperature sensor. This is significant as Sonoff BASICZBR3 is only shipped with TI Z-Stack Home 1.2 Zigbee router firmware and I was told no one else had ported TI Z-Stack 3.0 Zigbee to CC2530 chip so far. You’ll find source code on Github, and a […]

MIOTY Silicon Vendor Agnostic, Scalable LPWAN Standard to Take on LoRaWAN, NB-IoT

[April 6th update: The article was updated to reflect Fraunhofer invented the technology] There are plenty of LPWAN (Low Power Wide Area Networks) standards designed for low power, low bitrate and long-range connectivity with the most popular currently being NB-IoT and LoRaWAN. But Texas Instruments has joined other smaller companies (Fraunhofer, Ragsol, STACKFORCE, WIKA…) to form the MIOTY alliance in order to develop and promote a new LPWAN standard operating in the sub-GHz range called MIOTY. Texas Instruments explains MIOTY was born due to a lack of scalability and robustness (interferences issues) of current LPWAN solutions. But just like other similar low power WAN standards, it aims to support long-range while achieving long battery life, but MIOTY is also supposed to help IoT developers mitigate performance degradation in high-node-count networks. MIOTY works in the same license-free bands (868 MHz, 915 MHz …) as LoRa radios with no costs involved to use the radio spectrum. The solution offers a star network […]

$4 ITEAD CC2531 Zigbee USB Dongle Works with Zigbee2MQTT Out of the Box

Some of ITEAD Studio’s Sonoff home automation devices include Zigbee connectivity with for instance Sonoff BASICZBR3 smart switch or a version of Sonoff S31 smart socket with integrated Zigbee. Those devices usually work via a Zigbee enabled gateway that could be a router, Raspberry Pi SBC, or mini PC, which ITEAD did not offer so far. But to help people making their own Zigbee gateway the company is now selling a low-cost ($3.99) CC2531 USB dongle preloaded with CC2531ZNP-Prod firmware (Zigbee coordinator firmware), and compatible with Zigbee2MQTT open-source Zigbee to MQTT bridge once plugged into a PC, Raspberry Pi, or another Linux SBC. ITEAD CC2531 Zigbee USB dongle specifications: MCU – Texas Instruments CC2531F256 Zigbee and IEEE 802.15.4 wireless MCU with 8kB RAM, 256kB Flash pre-loaded with CC2531ZNP-Prod firmware for zigbee2mqtt application Host Interface – USB 2.0 male port Expansion – 8-pin unpopulated header with 8 I/Os Debugging – Debug connector Misc – 2x user buttons, 2x user LED’s Dimensions […]

Electrolama to Launch 802.15.4/Zigbee USB Dongle and Raspberry Pi “HAT”

Electrolama (@omerk and friends) has been working on two open-source hardware 802.15.4/Zigbee projects with “zig-a-zig-ah” (aka “zzh”) USB stick based on Texas Instruments CC2652R SimpleLink multi-standard wireless MCU and Zoe (Zigbee + Poe) development board based on Raspberry Pi HAT form factor and powered by TI CC2530 SimpleLink 2.4 GHz SoC alongside CC2592 range extender. Both boards are released under an Apache-based Solderpad Hardware License 2.0, and target users of the Zigbee2MQTT project.  The boards could soon also get native support in Home Assistant via the “zigpy-cc” library which adds support in ZHA (Zigbee Home Automation) integration component. Zig-a-zig-ah USB Stick Preliminary specifications: WiSoC – Texas Instruments CC2652R SimpleLink multi-standard wireless MCU with support for Thread, Zigbee, Bluetooth 5 Low Energy, IEEE 802.15.4g, 6LoWPAN, and proprietary systems. (Note: CC2652RB is also considered as it does not require an external crystal oscillator) Host Interface – USB via CH340 USB-UART bridge Misc – Push-button on BSL (bootstrap loader) pin for programming Debugging […]

Reolink Argus PT Review – A Solar powered Pan-Tilt Security Camera

Last year, I reviewed Reolink Argus Eco solar powered security camera, and I’m still using it to date. It’s working fairly well, although sometimes motion detection will not be triggered, or triggered too slowly so it’s not impossible to miss important footage. The PIR function can be tweaked so maybe it’s just a question of finding the right settings for a given location. Nevertheless, the company has now launched a new model called Reolinkg Argus PT that is very similar to the Argus Ego but with PT (Pan, Tilt) function, and I received a sample for review. Since both models are so similar, I recommend reading Argus Eco review first, as I’ll focus on the differences. Reolink Argus PT Unboxing I received two packages like las time: the camera itself, and Reolink solar panel. The camera comes with a WiFi antenna, a wall-mounting set, a USB cable, and some documentation. The camera includes a microphone and a speaker… As indicated […]

mDash Cloud platform for IoT Devices Targets ESP8266/ESP32, STM32, and TI CC3220 Wireless MCUs

Cesanta (a company based in Dublin, Ireland) recently launched mDash – an IoT cloud platform for administration of various IoT modules. This platform supports Espressif’s modules ESP32 & ESP8266, STM32 (L4,M4) and TI CC3220, and offers a bunch of features which are known to be  challenging tasks in the IoT world. This includes OTA (Over-The-Air) firmware updates, remote configuration and administration, alerts and notifications, remote device control and file management. This can be achieved through 3 programming platforms – Arduino IDE, ESP-IDF and through Mongoose OS. For evaluation and testing purpose mDash offers a simulator that run as a docker container. Refer our previous post, to understand how to get started with Cesanta’s Moongoose OS for ESP8266. Basic WorkFlow mDash Library The company offers reference firmware/library for the defined hardware platforms. This been implements by using secure MQTT for communication, re-connection and initial provisioning with mDash cloud. You can find the library for ESP32 & ESP8266 with a few examples […]

Reolink Argus Eco Review – A Sub-$100 Solar Powered Security Camera

Reolink Argus Eco IP Camera Wall Mounted

I’ve been thinking about installing one or more IP camera in my home for a while, and for ease of installation and considering I’m renting, my preference was to go with one of those battery IP cameras similar to Amazon (Immedia) Blink IP camera or Eufy EverCam security camera that last six months to one year on a single charge. But earlier this year I came across Reolink Argus 2 battery powered security camera that looks like good value at $100, and also came with an optional solar panel so you don’t have to ever charge the camera.  The company latter contacted me to know whether I’d be willing to try out their latest Reolink Argus Eco camera with similar features but an even lower $89.99 price tag. I got my sample a few weeks ago, and I had time to install it, and play around with the camera during that time, so  I’m now ready to report my experience […]
