+# Concepts — PSB (Post Secondary Brewing)
+
+Chris and Susan's craft brewery. Three agents: psb-thinking (planning), psb-gemma (brewhouse ops), psb-business (business side).
+
+## Active Projects
+
+| Project | Status | Key Concepts |
+|---------|--------|---------------|
+| Fermentation Dashboard | Planning | Home Assistant, TILT hydrometer, Grafana, dashboarding |
+| Brewery PID Replacement | Prototyping | ESP32-S3, ESPHome, Home Assistant, PID, PT100, custom PCB |
+| Toast POS | In use | Point of sale, product mix reports, email export |
+| Pi-hole (brewery) | Not started | DNS, ad-blocking (separate from home Pi-hole) |
+
+## Core Skills
+
+- **Brewing chemistry** — fermentation, yeast, malt, hops
+- **Home Assistant** — telemetry dashboards, TILT integration
+- **ESP32/ESPhome** — brewery sensor integration
+- **Toast POS** — sales reporting, product mix analysis
+- **PCB design** — custom PID controllers (Chris's growing skill)
+- **PID control** — temperature regulation for brewing vessels
+

+
+## Gap Analysis for Chris (at brewery)
+
+Chris is strong on: brewing, electronics, PCB design
+Chris is weak on:
+- **Home Assistant YAML** — configuration, automations, templating
+- **Dashboard design** — making data look good (Grafana, Lovelace)
+- **Software integration** — wiring multiple systems together
+
+## Recurring Topics
+
+1. **Temperature control** — PID for vessels (HLT, mash tun, boil kettle, fermenters)
+2. **Home Assistant** — telemetry dashboards, sensor integration
+3. **Custom hardware** — ESP32 + PT100 + SSR for temperature control
+4. **Data visualization** — making fermentation data readable
+5. **PCB design** — custom brewery controller boards
