Finances management web app

Finances management web app thumbnail
Most banks nowadays provide e-banking interfaces that allow clients to monitor the state of their accounts. However, each bank has its own system and the provided interfaces sometimes lack functionalities. Consequently, I decided to create my own finance dashboard, that combines information regarding multiple accounts. Currently I use it to keep track of my bank accounts balance over time as well as provide a breakdown of my transactions.

Air conditioners consume a fair amount of electricity. As such, forgetting to turn one off before leaving one's home can result in an expensive electricity bill. This is a Wi-Fi enabled controller for air condtioners, which can turn the unit on or off according to MQTT messages. It is built around an Wemos D1 mini and interfaces with the AC using an IR LED.

IoT heater controller

IoT heater controller thumbnail
The thermal insulation of my apartment not being the best, I decided to buy an electric heater in order not to freeze during cold winter nights. However, the one I got was probably too powerful for my needs and letting it run for too long would heat up my place too much. Thus, I added a wifi enabled controller to it so its operations are controlled by my home automation system.
