Matter 1.4 specification improves multi-admin and energy management, adds new devices like solar panels, batteries, and water heaters

Matter 1.4

We covered the Matter 1.3 specification in May 2024, but the Connectivity Standards Alliance is wasting no time and the Matter 1.4 specification is already out with features and improvements such as “Enhanced Multi-Admin”, Matter certifiable Home Routers and Access Points, energy management enhancements, and several new device types such as solar power equipment and batteries. Matter has been deployed in millions of Smart Home products in just a few years and aims to enable interoperability between devices from multiple vendors. Paisit reviewed a few Matter products from SONOFF including the MINIR4M Smart Switch, SONOFF Zigbee Bridge Ultra, and SwitchMan M5 Matter wall switch, and while Matter interoperability is working since devices can be controlled from Matter-compatible apps (e.g. Apple Home), users do lose some features found in the “native” app such as eWelink in the case of SONOFF devices. Matter 1.4 key improvements and new features: Home Routers and […]

EBL MP1000 Review – A 1000W portable AC/DC power station with solar panels

EBL MP1000 solar panels

Hey, Karl here and I am getting old. I guess middle age is more accurate. Two wonderful kids and I want to stick around for a while. I have not been feeling well and as a result, I picked up strength training as a form of exercise. I started with an adjustable bench and a set of adjustable dumbbells. I trained with them for about 3 months in my office. I had just enough space. I was hooked. I dove in and learned as much as I could on current best practices, and developed a spreadsheet for tracking progress. I started to outgrow the 55lb/25kg adjustable dumbbells with several exercises and the next step was a squat rack, bar, and Olympic weights. My problem was the lack of space. I had a building that was poorly organized. After a bit of organizing, I was able to carve enough space for […]

DFM8001 indoor energy harvesting kit harnesses solar energy (and mechanical, thermal, RF energy with extra hardware)

DFM8001 Indoor Ambient Energy Harvesting Kit

DFRobot DFM8001 indoor ambient energy harvesting kit can power IoT devices by harnessing solar energy, and the company claims it can also capture mechanical, thermal, and RF energy from the local environment but there’s no way to do that with that kit without additional hardware. The DFRobot kit is comprised of an evaluation board with the company DFM8001 energy harvesting module, two pluggable supercapacitors, and a solar panel used as power input. You could also use other sources emitting at least 150 mV gathering energy from RF, thermal, or mechanical sources. The board features two outputs one low-voltage (1.2-1.8V) terminal up to 20mA, and a high-voltage (1.8V-4.1V) terminal up to 80mA, and two battery connectors plus a few jumpers for configuration. DFM8001 energy harvesting kit specifications: Operating voltage – 3.3V to 5.5V DC Cold start condition – Input > 400mV 15uW Sustaining voltage after cold start – 150mV. Input voltage […]

Solar power manager module supports 6V-24V input range, battery charging, MPTT function, and outputs 5V/3A

Raspberry Pi 4 solar panel

Waveshare Solar Power Manager Module (D) is a compact power module for solar panels with support for 6V to 24V input, MPTT (Maximum Power Point Tracking), and battery charging. It outputs 5V up to 3A via a USB-C port or terminal block and should be suitable for a range of projects. A few weeks ago, we wrote about the FireBeetle 2 ESP32-C6 IoT development board with DFRobot highlighting support for solar charging of lithium batteries thanks the the CN3165 chip. But with a range of just 4.5 to 6V for solar panel input and a lack of support for MPTT, several readers were unimpressed by the solution. The Waveshare Solar Power Manager Module (D) recently popped up in my news feed, and I thought it might be worth a look. Waveshare Solar Power Manager Module (D) specifications: Solar panel input 6V to 24V via DC jack or 2-pole screw terminal […]
