The plan was to build an automated watering system that I can drive from Home Assistant – Ideally with some logic about when to run, and weather etc.

1. RaspberrypPi – 3a
2. FlowSensor – Seed Studio SS101990055
3. Water Solenoid- ADA997
4. 12V power Supply
5. 4ch 5v Relay Board – CE05279

Parts i missed and had to go back for

1. Terminal Strip – HM3194
2. Logic Level board (3.3v to 5 v) – XC4486
3. 12V switch – STO582
