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 hub-dimmed 4×8 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 Settings › 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.
