Lamps, tariff and the energy estimate. Schedules stay on the Light desk; this is what they cost and how bright they may go.
Schedule (Hub scope)
| Row | What it does |
|---|---|
| Automatic photoperiod | The hub runs the lights-on window for the 2×4 lamp. Off means the lamp only moves by hand. |
| Lights-on times | A link to the Light desk: the 4×8 and 2×4 on-times are clock entities edited there. |
| 2×4 photoperiod hours | Length of the lit window. |
| Minimum dark hours | The dark period the hub protects; a violation is a critical alert. |
| Sunrise ramp · Sunset ramp | Ramp minutes for the dimmable lamp (default 30 each). |
Fixtures
- SF1000 target brightness (Hub): the level the ramp arrives at (default 75 %).
- Light brightness scale (Brain): multiplies lamp brightness targets; 1.0 is the schedule's own value.
- CO₂ supplemented (Brain, default off): off, the generic flower DLI band is 30–40 mol/m²/d (40–50 in late flower); on, it is 35–55. It changes the Light desk verdict and the run report's DLI evidence; it controls nothing.
- Fixtures and nameplate watts: a link to the Light desk's fixtures panel.
- SF1000 ramp floor (Advanced, Hub): the lowest brightness the sunrise and sunset ramp passes through (default 32 %).
The 4×8 / 2×4 canopy distance (cm) rows for the DLI estimate are on Settings › Integrations › CannaLib. Empty uses the maker's recommended hang height for the current stage, shown as an estimate.
Devices on a space
Devices in each space lists every lamp, fan and plug per tent with its tier: driven (level and read-back), switched (on/off through a plug) or known (counts toward power and airflow, no control). Add a device takes an id, label, kind, watts and tier; a fan also needs which way it moves air and its nameplate CFM. A device row can be matched to a DSC-KitLib product with Find product: search by brand or model; the match is stored with the device.
- The product's nameplate watts lock the device's watts on the Lamp power, Fan power and Appliance power cards in Settings › Devices › Inventory (marked FROM DATABASE). Unmatch the product to type watts by hand.
- A matched lamp brings its maker PPFD map, spectrum and recommended hang heights to the Light desk.
- A matched fan shows the maker's free-air CFM beside what it measured in this duct, and Use maker values offers the maker's nameplate CFM and duct size (a duct size you typed is kept; a calibrated fan keeps its curve).
- A matched heater, heat mat, humidifier, dehumidifier, AC or pump says whether it restarts after power loss, or that the maker has not published it.
- A device bound to a lane role (for example the Tuya Lamp plug · 4×8) shows whether that role is bound, its friendly name, on/off and whether the link is live.
Move to… on a device row moves it to another space with its label, watts, product match and binding. Use it when a lamp or fan physically moves tents. The kit's built-in devices stay moved: the brain does not re-create a moved built-in in its old space.
A space with more than one lamp combines them: the DLI estimate adds each bound lamp's maker map at its own dim level and hours.
Tariff (Brain scope)
The Space energy card: watts per device and Tariff ($/kWh), the rate per kWh for each time band, each with Update. The energy estimates show the currency symbol from Preferences. The energy cards use it for daily and projected cost per space. Space energy is per tent; there are no lighting controls on plant cards.
