I posted some of my experience in the past but here's the final result -

Components:

- Hydrosys

- Chirpstack - lorawan (mqtt interface with hydrosys)

- Home Assistant for visual monitoring and alert

- Lorawan humidity sensors

I have yet to fully turn on the automation which would turn the drip sprinklers on but certainly the system is capable of doing it. The Lorawan sensors send data to Chirpstack to be decoded and converted to readable measurements, Hydrosys records into a database then finally transmits to Home Assistant. I did go with Lorawan sensors as they are more efficient on batteries, where batteries can last 1-2 years depending on the frequency of transmission.

I understand I have a lot of parts for the automation, hopefully in the near future I can reduce to a single system under the Home Assistant OS. Unfortunately not a single system can meet my needs. It would be great is Hydrosys was completely integrated into Home Assistant!

Given the harsh Arizona weather, my goal was to (1) ensure palm trees are healthy, (2) conserve water. Minimum soil moisture needs to be between 54-58%. The photo shows higher % because it got watered yesterday. Within 3 days it goes from these higher levels to about 55%.
