Wavie is an automated water tester for reef aquariums. It reads pH, ORP, salinity and temperature from probes in the tank, and measures alkalinity, calcium, magnesium, nitrate and phosphate by mixing a small sample with reagents and reading the colour that develops.

This wiki explains how Wavie works, part by part, in more detail than the website. It describes only what has been decided. Wavie is still in development, so where something is planned rather than built, the page says so, and anything still being worked out is left out until it is settled.

• How Wavie works: one test, from tank to result
• Specifications: every settled number in one place

• Fluid path: the pump, the rotary valve, the manifold, the tubing and the cell, and why reagent cannot reach the tank
• Optics: the three-wavelength photometer
• Electronics: the main board and the boards around it
• Probes: pH, ORP, salinity, temperature and dissolved oxygen
• Lighting: the RGB ring and the logo
• Enclosure: the tower, its tiers and its connections

• Reagents: what they do, the subscription, and the launch offer
• Software and app
• Expansion: the CAN bus

• Wavie Power: an eight-outlet switched power strip
• Wavie Dose: a dosing pump driven by Wavie's results

• Beta Kit: what is in it and what to expect
• Parts and links: the components Wavie is built from
• Design files: the CAD and the circuit boards
• Care and calibration: what needs attention, and how often
• Repair and parts
• Licence: what you may and may not do with the designs
• Glossary and community: the terms used here, and where to ask questions
