Jesús has attached various sensors for collecting data as we as a Raspberry Pi camera to take pictures of the room. He has developed energy efficiency algorithms running in the cloud which make decisions based on the data from the sensor and after that ANAVI Infrared pHAT takes care for transmitting commands as a stream of infrared signals to his air conditioner.
Michel runs a local Apache2 web server on the Raspberry Pi Zero W and the Infrared pHAT can record and play back the infrared signals from any brand of remote control using the popular open source software Linux Infrared Remote Control (LIRC). He shared details in Crowd Supply and GitHub.
Furthermore Michel crafted a fantastic wooden box and shared with us a couple of photos!
ANAVI Infrared pHAT is an open source hardware add-on board that converts your Raspberry Pi into a smart remote control that can bring your old consumer electronic devices, like air conditioning, TV, set top boxes and Hi-Fi systems to the Internet of Things (IoT) era.
