Karl’s Home Automation Project – Part 2: 433 MHz / WiFi MQTT Bridge, Door & PIR Motion Sensors

Karl here again for part 2 of my home automation project. We will be looking at how to automate your lights based on time of day and motion. In the first part we setup Home Assistant and uploaded firmware to basic Sonoff Wifi switches. Today we will setup a 433 MHz to MQTT bridge and some sensors. 433 MHz Depending on your country 433 MHz is an open frequency to use to communicate with. There are hundreds of different types of devices that use 433 MHz to communicate information. We will be focusing on 2 today from Gearbest: WMS07 motion sensor (left) and WDS07 door/window sensor (2 parts, right). I am not taking the door/window sensor apart, since it is super basic, but I’ve included some photos of the PIR motion detector. 433 MHz Bridge While contemplating how to get presence on a per room basis I ran across this […]

Karl’s Home Automation Project – Part 1: Home Assistant & YAML, MQTT, Sonoff, and Xmas Lights

Karl here. I am here to write about my home automation project. First thing I want to say is that I am very cost conscious and I don’t mind putting in extra effort into the setup of things to keep costs down. I did invest a lot of time and had to do a lot of reading to get my project going. It took while and I received a lot of groans from my wife while testing. I am still in the process of tweaking things. I started watching a series of videos on YouTube from Bruh Automation. He introduced me to Home Assistant. It got me really excited. He uses a Raspberry Pi as a server but I already had a Wintel Pro CX-W8 Smart TV Box which I use as a server. I run 3 Minecraft Servers, Emby Server, iSpyConnect DVR (2 IP Cameras), Unifi wifi controller, and […]

22€ Olimex ESP32-EVB ESP32 Development Board Features an Ethernet Port and Relays

We already have a good choice of ESP32 development boards, but none of the ones I’ve seen make use of the Ethernet MAC interface found in Espressif ESP32 SoC. Olimex has changed that with their ESP32-EVB featuring ESP32-WROOM32 module as well as one Fast Ethernet port and two relays. Olimex ESP32-EVB specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet RJ45 port External Storage – micro SD slot Relays – 2x 10A/250VAC relays Expansion 40-pin GPIO female header (2.54mm pitch) UEXT connector for sensors and modules Misc – 2x user buttons Power Supply 5V power jack LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery The company still have to write software samples, and do some testing to make sure the board work before going into mass production. Once everything is cleared, the board will be sold […]

How to use Sonoff POW with ESPurna Firmware and Domoticz Home Automation System

Sonoff POW is an ESP8266 based wireless switch with a power meter that comes pre-loaded with a closed-source firmware that works with eWelink app for Android or iOS by default. But we’ve also seen Sonoff POW, and other Sonoff wireless switches from the same family, can be flash with open source firmware supporting MQTT (Message Queuing Telemetry Transport) lightweight messaging protocol such as ESPurna, and I initially sent data from Sonoff POW to ThingSpeak via an MQTT broker (mosquitto) to draw some pretty charts. I did that with the switch connected to a lightbulb, but I’ve since installed Sonoff POW in my office to measure the room’s power consumption minus the ceiling light and aircon as shown below. Sonoff cable mechanism is really a pain for hard copper wires, as they are hard to push inside the mechanism, and something come out. I finally managed by it took longer than […]

How to Install Domoticz Home Automation System in NanoPi NEO and Other ARM Linux Boards

I’ve recently started experimenting with IoT projects, and the first hurdle is to select the hardware and software for your projects are there are simply so many options. For the hardware your first have to choose the communication protocols for your sensors and actuators, and if you are going to go with WiFi, ESP8266 is the obvious solution, used together with your favorite low cost Linux development board such as Raspberry Pi or Orange Pi to run some IoT server software locally or leveraging the cloud. But the most difficult & confusing part for me was to select the server software / cloud services as there are just so many options. I prefer having a local server than something running only in the cloud, as my Internet goes a few hours a month, so I started with a solution combining ThingSpeak with MQTT gathering data from Sonoff power switches running […]
