A modified version of Flaura by Martin McMaker (https://www.thingiverse.com/thing:4921885)\ It uses Home Assistant instead of Blynk

I started this project at the end of May 2022 and have worked on it a bit on and off. Then I saw the following thread and decided to publish my progress in case someone could use what I have made:
https://community.home-assistant.io/t/invitation-project-suggestion-an-automated-potted-plant/
Martin Vinter made the thread and put his design files here: https://github.com/MartinVinter/Flaura2
The software seems to be working, but I haven't tested it long term.
I am working on a complete redesign of the pot itself, which will require less silicone to make watertight

I bought everything on AliExpress because they have the option to combine all items in one big package when shipped to the EU. (Tired of asking for sellers to resend small items that got lost in shipping)

I did not want to order custom-made PCBs. I use a prototype board instead. I use the ESP32 called "TTGO T-Energy" because it has low power usage in deep sleep mode and a 18650 battery holder
