Device status
OHT Slave
WiFi
Scan for nearby networks and switch if needed. The device tries the new network for up to 20s and automatically reverts to the current one if it fails to connect — a typo can't strand it.
Notifications
Get a notification on this device for every fault, fault resolved, pump start/stop, and offline/back-online event — even when this tab isn't open. No app or account needed beyond this browser.
Fault history
- No faults logged.
Activity log
- No activity logged yet.
Device log
Meaningful firmware-side events (boot, WiFi, faults, retries, OTA) — not a live trace, updates once per poll.
- No device log entries yet.
Scheduled runs
Start a pump automatically at a fixed time each day. The device's safety limits (overload, dry-run, OHT full) still apply — the schedule just issues a Start command, the same as pressing it on the dashboard.
Only admin accounts can edit schedules.
Firmware
Upload a .bin below, or drop one on the server named
water_controller_<version>.bin — either way it shows up here
for approval before installing.
OHT Slave
Upload a .bin named oht_slave_<version>.bin to update the slave sensor node.
Settings
Changes reach the controller within ~4s (next telemetry cycle) — no re-flash needed.
Only admin accounts can edit these — ask an admin to change them.
