Hi everyone, I’ve been diving into the world of smart home automation lately, and I’m thrilled to share my latest project with you all! 
I’ve always been passionate about sustainability, so when I decided to upgrade my home, integrating a rainwater collection system was at the top of my list. The system I’ve designed includes two large rainwater tanks, a backup well connection for dry seasons, and multiple stages of filtration to ensure the water is safe for household use. I’ve also incorporated a roof-mounted concrete tank to store the treated water. While the setup itself is pretty standard, the smart monitoring aspect is where things get exciting! 
To keep track of my water system’s performance, I’ve installed a variety of sensors throughout the process. Ultrasound sensors monitor water levels, while DN8 transducers check pipe pressure and flow. I’ve even got temperature sensors to keep an eye on the water temperature at different stages. All of these sensors are connected to Wemos D1 Mini Pro boards, which are fantastic for handling both 5V and 3.3V sensors. The data is then fed into my Home Assistant setup via MQTT, thanks to a Synology NAS that’s also hosting InfluxDB and Grafana for data visualization. 
One area I’m still exploring is water quality monitoring. While I’ve added pH sensors to track acidity at various points, I’m eager to incorporate more comprehensive testing. I’ve come across some affordable sensors from brands like Bante that measure turbidity, dissolved oxygen, and conductivity, but I’m curious if the community has any recommendations or experiences with these. Any insights or tips would be invaluable! 
I’d love to hear how others have approached similar projects. Have you integrated smart water monitoring into your home? What tools or techniques have you found effective? Let’s discuss and share our experiences! 
Cheers,
