LUNA

Requirements for NINA integration

• NINA v3.x — nighttime-imaging.eu (free)
• NINA Advanced API plugin (free, installed from within NINA)
• Port: 1888 (default), API Enabled: ON
• LUNA and the NINA PC on the same WiFi network

Requirements

Getting Started

Example: Full Observatory Automation

-- LUNA Lua script: check weather, then start NINA sequence
local resp, code = http.get(
  "http://192.168.x.x/api/v1/observingconditions/0/humidity", 2000)

if code == 200 then
  local humidity = -- parse resp
  if humidity < 80 then
    http.post("http://192.168.x.x:1888/v2/api/sequence/start", "{}",
              "application/json", 3000)
    log.write("Sequence started. Humidity: " .. humidity .. "%")
  else
    notify.set("Humidity too high (" .. humidity .. "%). Imaging skipped.")
  end
end

---

Lua API (inside scripts)

-- Serial control
serial.write(cmd)
serial.read(timeout_ms)
serial.query(cmd, timeout_ms)

-- HTTP (LAN only — ASCOM/Alpaca/NINA/Stellarium/Vixen STAR BOOK TEN)
http.get(url, timeout_ms)
http.put(url, body, content_type, timeout_ms)
http.post(url, body, content_type, timeout_ms)  -- v5.9.2

-- UDP (Vixen Wireless Unit)              -- v5.9.3
udp.begin(local_port)
udp.connect(host, port)
udp.write(data)
udp.read([timeout_ms])
udp.close()

-- Logging & data passing
log.write(message)
log.read([n])       -- n omitted = latest line
log.save()          -- persist to flash
log.load()          -- restore from flash

-- Hardware
hw.delay(ms)
hw.millis()
hw.free_heap()
hw.led(0 or 1)

-- Notify Claude
notify.set("message")

-- Script chaining
luna.run("next_script_name")

★ New in v5.9.2 — NINA Astrophotography Integration

LUNA now controls NINA (Nighttime Imaging 'N' Astronomy) — the world's most popular free astrophotography software — directly via its HTTP API.
