A home aquaponics unit for aromatics — fish and plants in one closed loop — built around a recovered fish tank with a CNC-fabricated structure. The build is in the fabrication stage; its sensing and automation reuse the GROUU WiFi node and the greenhouse sensor set, reporting into the same server stack.
Aquaponics couples a fish tank to a grow bed: fish waste feeds the plants, the plants clean the water. GROUU's role is to watch that loop and, later, to keep it in range — the same pattern as every other node. There is no dedicated firmware in this repo yet; the plan reuses the WiFi node for sensing and the actuator module for pumps and feeders, both publishing over MQTT to the edge server.
The precursor fishTank project — a NodeMCU + ESP-01 with a 3D-printed automatic feeder — is the starting point being folded into GROUU. Sensor and control code will follow the reference nodes rather than be written from scratch.
Design-level so far — a mix of recovered material and digital fabrication. No priced BOM is published yet; electronics reuse the reference nodes.
