How to Use Sonoff POW ESP8266 WiFi Power Switch with MQTT and ThingSpeak

ITEAD Studio’s Sonoff is a family of cheap home automation products based on ESP8266 WiSoC, and I’ve already tested Sonoff TH16 wireless switch with a humidity and temperature sensor using the stock firmware and eWelink app for Android or iOS. It works, but up to recently it required a registration to a cloud service (the company will now allow use from the local network), and the source code is closed. So for the second device under review, namely Sonoff POW wireless switch with a power consumption monitor, I decided to install ESPurna firmware working on ESP8266 Sonoff devices and NodeMCU, as it’s open source, supports Sonoff POW natively, includes a web interface to control the device from the LAN, and includes an MQTT client. MQTT (Message Queuing Telemetry Transport) is a lightweight publish/subscribe messaging protocol used to control IoT sensors and devices, and it’s a popular method to gather data […]

How to Install ThingSpeak in Ubuntu 16.04

Last week-end I installed ESPurna open source firmware with MQTT server on Sonoff POW WiFi switch, and the next step is find a way to draw power consumption charts in some web based interface. We could do this in the IoT cloud with services like Xively or ThingSpeak, but since one of the goals of replacing the default firmware was not to rely on a proprietary cloud based solution, I decided to find a way to draw those chart in a local server, and it so happens that ThingSpeak is also open source with the code available on Github. Hardware platforms like NanoPi NEO / NEO Air, or Orange Pi Zero boards appear to be particularly well suited for the task of running an MQTT broker and Thingspeak, but at first I wanted to install ThingSpeak in my own Ubuntu 16.04 computer to have a try. As you can see […]

Getting Started with Pine64 PADI IoT Stamp – Part 2: Serial Console, GCC SDK, Flashing & Debugging Code

PADI IoT Stamp module powered by Realtek RTL8710AF ARM Cortex M3 WiFi SoC is a potential competitor to Espressif ESP8266 modules. Pine64, the manufacturer of the module, sent me their kit with a $2 IoT stamp, a breakout board, a USB to TTL debug board and a J-Link debug board. In the first part of the review I’ve shown the hardware and how to assemble PADI IoT stamp kit. In the second part I’m going to write a tutorial / getting start guide showing how to control the board with AT commands, build the firmware with GCC SDK, and finally demonstrate how to flash and debug the firmware with the J-Link debugger. The Quick Start Guide indicates you need to connect the USB to TTL debug board to UART2 instead of UART1 as I did on the very similar B&T RTL-00 RTL8710AF module, and set connection settings to 38400 8N1.
