After several iterations and data collection, I've created a PCB to neatly connect the Raspberry to the relays/sensors which includes 4 analog inputs to connect analog sensors (0-5v). I called it the "Automatio/Irrigation Hat". I've tested it with several sensors including the analog capacitive hygrometers. Using the analog inputs, among the other things, I can now verify and chart the voltage level of the battery of my Solar irrigation system.
The board can be connected to up to 16 relays, which can be irrigation lines or other actuators.
The Board is available for sale at the following link:

Buying the board can be a great way to contribute to this project.
NOTE: the hydrosys4 project can still be implemented without any custom board, all the supported hardware configurations/connections are described in the website.
Thank you Angelo, yes I have all the parts so will make the changes as per the schematic.
Yes its interesting how the rain sensor acts as a virtual tipping bucket, turning on and off with rain showers during the day and eventually filling the bucket and switching off for a day, this is user configurable on the rain sensor.
Hello,
Yes, you can definitely solder the missing parts of the board and use the Hygro1 and Hygro2. Note that you will need the MIC2026-1 and also the resistors that are close to Hygro1 and Hygro2. These ports are intended for the direct connection of metallic probes, according to the schema in the link below:

For the configuration, you need to go to the hardwaresetting page and select the relevant preset HW configuration:
Thanks for the tip about the rain sensor, it's quite interesting technology compared to the standard rain sensors.
Hello Angelo
Firstly thank you for all of your ongoing effort with hydrosys4, I am now running one system as a lawn irrigation system and working on a second system to water my wife's vegetable garden.
Secondly, my V10.4 irrigation hat arrived today. it looks great and I can wait to install it!
I have a question. I would like to add a resistive soil probe to the board and have already have the MIC2026-1 and other small parts, I can see on the PCB the locations for these, can I simply add these to utilise the "Hydro 1 and Hydro 2" connections?
Also for information I have added a rain sensor to the lawn irrigation system for simplicity and wanted you and other to know that this unit is fantastic, though a little expensive. https://rainsensors.com/products/rg-11/
Thanks again
Ben
Hola, me gustaria comprar uno de estos, haces envios a Chile ?
Hi
If You have problems with HAT production I can send You offer for PCB
Hello,
Don't know the SEED GrovePI, my system is not designed for compatibility with it.
For the Stock, given that the logistic is messed up due to the CoronaVirus, hope by the end of this month to list some pieces for Sale.
Hello,
Could you tell me if hydrosys can work with SEEED GrovePi ? And i constat that the Hat is out of stock. When will be available ?
I just placed an order for the unit with the manual buttons, no knowing this board exist. Is it possible to alter my order?
What is the difference between the AutomationHat-v8 and v8-flat hardware settings?
When can we buy this great product again?
Hi, for this particular board, you can refer to the Tindie link below:
https://www.tindie.com/products/angelova/automationirrigation-hat/?pt=ac_prod_search
in the section "Minimal Irrigation System example" you can find what is additionally needed to start a basic irrigation system.
In the same page you can select the options to add the relay boards.
With this board is a 12v power supply still required for the solenoids or any other components?
