WebCRAFTS

LOCAL OR AUTONOMOUS CLOUD CONTROL

Operate CRAFTS directly, through a standalone ESP32, or with a gateway.

Measurements are never stored on the WebCRAFTS VM. This tab keeps every interval-120 row received during the current session in memory; the plot shows the latest 10. Rows are saved only when you explicitly export or start TXT saving.

STEP 1

Instrument connection

Disconnected

Operation mode

CRAFTS continues adaptive flow and an armed drain schedule if the browser disconnects. On an authorized reconnection, WebCRAFTS synchronizes the current profiles and re-arms a nonzero drain schedule.

STEP 2

DigiFruit cloud authentication

Not connected

Device nameConnected deviceConnection keyTable display name

Required for standalone Wi-Fi and gateway control. The secret remains only in this tab’s memory.

STEP 3

Flow control

Waiting for device

Adaptive mode uses the CO₂ band, limits, step, and startup flow.

Edit any control, calculation, or drain field, then use the single update button below. First use defaults to autonomous run at 10 L/h; the ESP32 keeps the last explicit revision and operates through Internet or browser interruptions.

STEP 4

Calculations, drain schedule, and local destination

No cloud revision checked

Connect the DigiFruit key to compare the saved revision with the revision reported by the ESP32.

Device recovery

Use only when the device is unresponsive. Queued measurements remain on the ESP32.

TXT filename

No destination selected · saving stopped

Choosing a destination does not start recording. Browsers expose the folder and filename, not the complete native path.

STEP 5

Current session results

Manual 14-column payload

Ready for CRAFTS data. Session rows stay in memory only until this tab is closed or reloaded, unless you explicitly export or start TXT saving.

Device diagnostics

Wiring prerequisite: never connect ESP32 GND to a 24 V negative. Pump black/blue return directly to the pump adapter negative; JZ-MOS GND remains open and unconnected. Both 24 V valve coils are parallel on the same VOUT+/VOUT- output and operate together.
