How does ETWAN swarm detection work?

ETWAN swarm detection requires a weight scale sensor assigned to the hive. It continuously monitors hive weight and fires a "swarm suspected" alert when a sudden, sustained weight drop is detected. Detection only runs during swarm season (March–August in the northern hemisphere), between 07:00 and 19:00 local time, and requires the outdoor temperature to be above the minimum swarming threshold. There is a 24-hour cooldown per hive to prevent duplicate alerts.

What triggers the hive collapse alert in ETWAN?

The hive collapse (hive health) alert fires when the HVS (Hive Vitality Score) drops to WARNING (score 30–49) or CRITICAL (score below 30). HVS is calculated automatically from nest sensor data and reflects colony health, thermoregulation quality, and recent trend. The alert resolves automatically when the score returns to STABLE.

What delivery channels does ETWAN support for alerts?

ETWAN supports three delivery channels: email (default, always available — can be directed to a custom address), SMS (Polish +48 mobile numbers only, requires phone verification), and push notifications (requires the ETWAN mobile app). All three channels can be active simultaneously. Each alert type can be independently routed to specific channels — for example, swarm risk can go to all three while device offline goes to email only. At least one channel must remain active per alert type.

How does ETWAN know when a gateway has gone offline?

ETWAN determines gateway offline status based on the gateway's configured reporting mode. Each gateway has a scheduled check-in interval (from 3 minutes in Turbo mode to over 10 hours in Ultra Power Saving mode). If a gateway misses its expected check-in by a calculated grace period, the offline alert fires. Slower reporting modes give a longer grace period before alerting — this prevents false alerts from normal deep-sleep cycles.

What are quiet hours in ETWAN?

Quiet hours are a configurable window during which non-urgent ETWAN notifications are held and delivered after the window ends. Quiet hours are enabled by default and run from 22:00 to 07:00. You can change the start and end time, or disable quiet hours entirely in Account → Notifications. Recovery alerts (when a condition resolves) may still be delivered during quiet hours.

Does ETWAN send a notification when an alert resolves?

Yes. All critical and system alerts in ETWAN resolve automatically. When the condition clears — a sensor comes back online, a hive health score improves, an anomaly reading returns to normal — ETWAN sends a recovery notification through the same channels configured for that alert type.

Which ETWAN plan includes swarm detection and hive health alerts?

Swarm detection and hive collapse (HVS health) alerts are available on the Hobby+ plan. Sensor anomaly alerts, gateway and sensor offline alerts, and seasonal advice are available on Hobby Smart and above. Task reminders are available on the Hobby plan and above. The Free plan does not include alerts.

What is the sensor anomaly alert in ETWAN?

The sensor anomaly alert fires when a temperature, humidity, or weight reading from a hive sensor is statistically unusual compared to that hive's recent history. ETWAN compares the current reading against a rolling baseline built from the hive's own data — not fixed thresholds. A separate alert fires per metric, so you know whether it is a temperature, humidity, or weight anomaly. Each alert resolves automatically when the reading returns to normal range.
