I used Blynk for this smart plant pot to save my drying plants. It comes with a 3D printed housing, capacitive soil moisture sensor, automatic watering, an integrated water tank, WiFi and data display plus push notifications in a smartphone app.
I have been working on this for almost 2 years now and have refined it many times. But I still find more things I would like to improve every day and this process is so much fun! 
A few days ago, I decided to start a youtube channel to share my learnings and create some step-by-step tutorials how to build this plant pot. Feel free to watch the first teaser
