Field troubleshooting
What to cover
- XCore shows offline in cloud: tunnel diagnosis, LAN connectivity, DNS, port 7000 outbound.
- XE-DIO164 won’t join MQTT: credential mismatch, wrong broker IP, LED pattern decoding.
- Alarms not firing: zone→input mapping, debounce, pre-alarm window.
- Notifications not arriving: user channel misconfigured, STOP opt-out, 10DLC throttle.
- When to open a support ticket vs. retry.
- Collecting a support bundle (what to grab from the XCore before escalating).
