My Beninca BULL 5M sliding gate is now on the IoT – ESP8266 + MQTT lets me open, close and check the gate state from my phone.

Self-made esp8266 gate controller
Installed a self-made esp8266 gate controller with magnetic switch status sensor, I can now open/close/read the statate of the gate from anywhere. #IoT #esp8266
RTS/CTS for ESP8266 ESP32 auto-reset
Interesting http://esptool.py wrapper that lets you use RTS/CTS for #ESP8266 / #ESP32 auto-reset on firmware flashing instead of the usual RTS/DTR method. Saves a few components thus reducing project cost. Description and code here https://github.com/jimparis/esptool-ftdi
BBoilRF
BBoilRF: my internet-connected relay actuator/gateway with battery powered wireless sensor support, designed primarily as a thermostat.
ESP32
First look at the ESP32: I got one of the 200 early beta boards of Espressif’s ESP8266 big brother, here are the specs and impressions.
RFM69 to MQTT gateway using ESP8266
An RFM69 to MQTT gateway on the ESP8266 – Andrey Balarev and I wrote the missing RFM69 driver to bridge sub-GHz nodes to Wi-Fi.
Local hostname for connected devices
Reaching a headless IoT device after DHCP: local hostnames with mDNS/NetBIOS instead of hunting IP addresses in the router UI.
The initial setup problem
The initial setup problem: how to get an IoT product onto the user’s Wi-Fi without killing their enthusiasm – options compared.
Tweeting silicon
A tweeting ESP8266, no proxy service involved – the chip talks to Twitter’s API directly, SSL and all.
Firmware Over The Air (FOTA) for ESP8266 SoC
Firmware Over The Air (FOTA) for the ESP8266 – why every embedded project needs remote updates and how I implemented mine.
DIY Internet connected smart humidifier
Turning my open source WiFi relay board into an Internet connected humidistat – fan coil heating kept our indoor humidity below 30%.
WiFi Thermostat with weekly scheduler
My WiFi thermostat with a weekly scheduler – why I swapped the SSRs for classical 8A relays and what changed on the board.
WiFi IoT 3 channel relay board with MQTT and HTTP API using ESP8266
My ESP8266 relay board: three solid state relays, MQTT + HTTP API, DHT22/DS18B20 sensor support – an open WiFi IoT switching platform.
ESP8266 powered web server + LED control + DHT22 temperature/humidity sensor reading
An early ESP8266 experiment: web server, LED control and DHT22 temperature/humidity readings on the $4.50 Wi-Fi chip that shook up DIY IoT.
