Online Water Tracker (Reduce Shower Time)

The goal of this project was to lower my shower time since I am spending way too much water/money there. And what better way than to see how expensive each shower is? That is why I built an online water tracker that not only tells me how much waster I am using, but also what it costs. Let's get started!

Step 1: The Arduino Circuit?

In the video you saw that I firstly created an Arduino prototype. If you are interested in doing that first then you can find all the information here like code, schematic and some pictures.

Step 2: ESP8266 Circuit

Here it is time for the final ESP8266 that I used in the video. It is basically the final online water tracker. Here you can find the schematic of the circuit as well as some pictures. Use them and the supplies listed before to create the circuit. You will find the code for the circuit in the next steps.

Step 3: 3D Print the Enclosure

Here you can find the .stl files for the enclosure. Use them print your enclosure and follow the steps I mentioned in the video. You can also download the enclosure files here: https://www.printables.com/model/257140-water-flow-online-tracker-enclosure

Step 4: Home Assistant Code/Configuration

This is probably the most difficult part. Like I said in the video Home Assistant required quite a lot of code/configuration. To make it easier for you I included all my created code/configuration here. And here is what you need to do:

Install ESPHome and write the ESPHome firmware onto the ESP8266
Upload my given flow.yaml code to the ESP8266
Install the file editor and edit your configuration file. You can find my configuration file attached.
Create an Automation that looks like my attached automation
Install the Home Assistant Community Store (Here is how to do that: https://hacs.xyz/docs/setup/download )
Install Lovelace Mini Graph Card through the Community Store ( https://github.com/kalkih/mini-graph-card )
Add the graphs and entities to your dashboard just like the pictures that are attached

DONE! I know this process can be tedious but in the end it should work.
