The idea
Water a courtyard garden and a few planters by soil moisture instead of a timer, using standard ½" BSP valves from a shop catalog and a small controller that fits in an IP65 box.
What Daedalus produced
Controller
PCBA with relay outputs, sensor inputs and Home Assistant integration
Assembly
Valve manifold built in the assembly builder from catalog parts
Zone plan
Four zones, pipe lengths and fittings in a garden model
Firmware
Moisture-based watering with frost protection
BOM
Device parts by MPN, garden parts by catalog code
Install guide
Step by step, from manifold to first watering run
What the red team found
Transformer too small for four valves
24 VA powers three valves at once. Fixed: zones run in sequence.
A valve that sticks open floods the garden
Fixed: maximum run time per zone and a master valve.
Pipes can freeze in winter
Fixed: drain point and a frost lock in the firmware.
Build it yourself
Change the number of zones, swap the valves for another catalog, or connect to a rain sensor. The assembly builder checks threads, coil voltage and power for you.
