  The M5Camera is a camera unit based on ESP32 chip has an OV2640 and also includes a PSRAM. As you may already know, M5Stack is an open-source modular toolkit for IoT developments based on ESP32. There are four versions of this camera (see Fig. 1). I got the M5-Camera B and this is a tutorial to use the camera to generate timelapse videos. However, this module doesn't have a microSD slot. Therefore, the application will publish the photos on an MQTT Broker, so that an MQTT subscrib...

  This article extends the tutorial about Hass.io and the Xiaomi Aqara Sensors that I've published months ago. That tutorial is part of the series of articles about Zigbee and the Rasbperry Pi using the CC2531 USB dongle. Here are the links:

  • Zigbee: Xiaomi Sensors using Raspberry Pi (without Gateway!)
  • Zigbee: Flashing a CC2531 dongle using a Raspberry Pi

  Last April, I published a tutorial about connecting the Aqara sensors to a Raspberry Pi without using the Xiaomi Gateway. To make that possible, I needed a CC Debugger to flash the TI CC2531 Zigbee Dongle. This debugger was used only one time, and then the Zigbee-USB dongle worked without any problem.

  In this article, I will cover a way to flash the CC2531 without the CC Debugger. This reduces project costs (about $10 for debugger + cable adapters) and waitin...

  This tutorial allows you to connect Xiaomi (or Aqara) sensors (e.g. door, pir, temperature, water, switch) to a Raspberry Pi or similar system without using any Xiaomi Gateway.

  This is what I will try to accomplish in this tutorial:

  1. Flash the USB-Zigbee Dongle with the correct FW
  2. Install a broker to connect to the sensors
  3. Configure the sensors using the...

  This time a quick tutorial to control your WiPy 3.0 / 2.0 or an ESP32 using Blynk.

  Blynk is the most popular mobile app for the IOT. Works with anything: ESP8266, Arduino, Raspberry Pi, SparkFun and others.

  I found a library to connect MicroPython to Blynk but it is only compatible with the WiPy 1.0. Thus, I modified it and made it compatible with the WiPy 3.0 / 2.0 and with the ESP32 running MicroPython. If you do not have any idea about MicroPython, I rec...
