Hello readers
Last two years my team spent to develop IoT platform to manage energy distribution across the grid to eliminate under-loads and spikes, at the same time providing smart capabilities for customers.
Smart Energy Distribution System
Sun Heater for Swimming Pool
This spring before launching swimming pool I decided to build an automated sun water heater which should heat the water during the sunny days.
Enigma: Air conditioner protocol reverse engineering
In my previous post I created new version of IR transmitter for air conditioner but didn’t explain the process of reverse engineering chinese IR remote for air conditioner.

Infared Remote Control rev 2.0
Couple of days ago I decided to create new one IR controller for my air-conditioner and make it more professional, smaller and reliable.
I used schematics from my previous project but simplified it by removing DH22 temperature sensor and decided to improve schematics by using my base circuit with additional pull-up and pull-down resistors and capacitors for ESP chip stability.
Weather station
Just completed soldering stable version of weather station based on ESP8266, it measures temperature and humidity using DHT22 sensor and also luminosity.
Own tracks on Google Map
Current post describes implementation of OwnTracks geo data and then draw they on Google Maps.
ESP12 Main Circuit
Below you can see my main circuit which I use in my projects. Based on my experience I’d suggest that this is most of the stablest version.

Pulse counter (rev 2)
Recently I built the second revision of my pulse counter to measure power consumption in my house.
The version is using plastic box and installed to DIN rail, it also has interface to re-programm ESP chip and reset button.
Home Media Center
Some time ago I decided to buy a 4K camcorder to capture some amazing videos across the world and then enjoining the same picture on my TV sitting at home. The idea was to have a window into places which I love.
Smart light switch
After some playing with different types of the switches which controlled lights through my Home Automation System I figured out best implementation of smart switch and in this post I will show you what I made.
