greenhouse-automation

Just a hobby project =) Greenhouse automation based on Raspberry Pi, Node-red and Pimoroni Automation Hat

Functionality to be

• Check soil moisture
• Water once every day if soil is too dry
• Check water level in reservoir
• SMS / email if reservoir needs refilling
• Input to Justini if reservoir needs refilling and filling statistics.

Software and Modules

• Raspberry Pi OS
• Node-RED - Running on Raspberry Pi
• Node-RED nodes for Pimoroni Automation HAT/pHAT - blogpost on using it

Hardware

• Raspberry Pi
• Automation Hat - Explanation on ports
• Arduino Soil Moisture Sensor
• 12V solenoid valve (closed when power off)
• Some USB charger
• 240 AC - 12V DC converter (IKEA) to solenoid
• Water hose
• Hose nipples etc.

Setup

Rasperry Pi

• Install Raspberry Pi OS
• sudo raspi-config and enable ssh, set hostname to greenhouse, change password, maximise disk space and update raspi-config
• sudo aptitupde update && sudo aptitude safe-upgrade
• sudo apt install build-essential git
• Install node and node-red - bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
• Make node-red start on boot sudo systemctl enable nodered.service
• Reboot
• Go to http://greenhouse:1880
• Install node-red-contrib-automation-hat with menu > settings > pallete > install
