SONOFF SNZB-05P review – A Zigbee water leak sensor tested with eWelink and Home Assistant

SONOFF SNZB-05P Zigbee Water Leak Sensor review

Today, we will review another new sensor from SONOFF, the SNZN-05P Zigbee water leak sensor. This is SONOFF’s first-ever water leak detection sensor. In the past, we have reviewed other Zigbee sensors that were upgraded from previous models. SONOFF enthusiasts will likely be pleased because a water leak detection sensor is something that should have been part of the SONOFF ecosystem for a long time. That is a bit late in the game, but it has a unique feature: an Extended Detection Cable that can detect water leaks. Let’s take a look! SONOFF SNZB-05P Water Leak Sensor Unboxing Inside the box, you’ll find the sensor, an Extended Detection Cable (2m), cable clips, and a small manual. The SNZB-05P is water-resistant with an IP67 rating (submersible up to 1 meter for 30 minutes). It uses a CR2477 battery, similar to other SONOFF Zigbee sensors, which should last several years. Both terminals […]

RAUC open-source OTA update solution for embedded Linux ported to Rock Pi 4 SBC

RAUC open-source OTA update solution enabling A/B updates for embedded Linux images has recently been ported to the Radxa Rock Pi 4 Model B SBC powered by a Rockchip OP1 SoC by the project’s maintainer, Leon Anavi working for Konsulto Group. If you run a Linux distribution like Ubuntu, Debian, or Fedora, packages and OS images are taken care of automatically or by running a few commands. However, software engineers who build custom embedded Linux images with the Yocto Project or Buildroot must handle this themselves. Luckily, there are already open-source OTA firmware update solutions such as Mender, Balena, Torizon, OSTree, Snap, or RAUC, and we’ll look at the latter today. RAUC (Robust Auto-Update Controller) was started by Pengutronix in 2015 and eventually adopted by the community. It’s a lightweight update client that runs on an Embedded Linux device and controls the A/B update procedure when a new firmware revision […]

Sipeed Tang Mega 138K Dock is a lower-cost GOWIN GW5AST FPGA + RISC-V development board

The Sipeed Tang Mega 138K Dock is a low-cost version of the Tang Mega 138K Pro development board launched last year with the GOWIN GW5AST FPGA + RISC-V SoC, two SPF+ cages, a PCIe 3.0 x4 interface, and DVI Rx and Tx ports. The new Tang Mega 138K Dock keeps a GW5AST FPGA SoC but with a 484-ball package that fits on a smaller system-on-module, and does without the SPF+ cages, replaces the PCIe 3.0 x4 interface with a PCIe 2.0 x4 interface, and only uses a single HDMI port for DVI Rx or Tx. Sipeed Tang Mega 138K system-on-module Let’s first have a look at the specifications of the SoM itself: SoC FPGA – GOWIN GW5AST-LV138FPG484A with 138,240 LUT4 1,080 Kb Shadow SRAM (SSRAM) 6,120 Kb Block SRAM (BSRAM) Number of BSRAM – 340 298x DSP slices 12x PLLs 16x global clocks 24x HCLK 8x transceivers at 270Mbps to […]

Zigbee Coordinator CC2652P7 1.0 runs open-source firmware, works with Zigbee2MQTT, Home Assistant, and ioBroker

The cod.m Zigbee Coordinator 1.0 (CZC 1.0) is a hybrid ZigBee coordinator that can be used to connect devices over a network (Ethernet/Wi-Fi) and USB. The ZigBee Coordinator version 1.0 is an upgrade of version 0.2 released in 2022. The CZC 1.0 replaces the Texas Instruments CC2652P2 chip with the much more powerful CC2652P7 chip, uses an ESP32-WROOM-32E module instead of the USR-K6 chip, and adds compatibility with Home Assistant (ZHA integration). It can create a Zigbee network and pair Zigbee devices over Ethernet, WiFi, or Serial (USB). It features the same Texas Instruments CC2652P7 chip as the SMLIGHT line of Zigbee Ethernet/WiFi/USB coordinators and USB dongles. There are two models of the CZC 1.0: a Power over Ethernet model and a model that can only be powered via USB-C. cod.m Zigbee Coordinator specifications: Zigbee SoC – Texas Instruments CC2652P7 Arm Cortex-M4F microcontroller @ 48 MHz with 704 KB flash, […]
