PiWaterflow

This is a resilient watering system, executed in a Raspberry Pi to control irrigation valves using relays. It's intended to be executed periodically (i.e. cron every 5 minutes).

• Requirements:
  • Raspberry Pi (any model)
  • Relays to control the valves
  • Optional control relay to enable alternative power inverter
• It supports 2 watering programs every day.
  • Programs can be forced at any time.
• Valves can be manually triggered.
• Programs, forced programs and manual Valves can be manually stopped.
• Metrics can be emitted to influxdb to register actions (programs and valves).
• This package fits with piwwwaterflow, so that it can be controlled via HTTP page.

TODO:

• Abort watering if humidity is above threshold (90% default). Send email warning
