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 […]
