- Ensure an Organization and Construction are selected.
- The Construction must have an MQTT topic. If missing, ask a Global Admin to configure it.
Connection failed
- A red alert says the connection to the device management service failed. Refresh the page.
- If it persists, check your network or contact support.
Commands not sent
- Select at least one device in the table. Commands with zero targets won’t send.
- If status stays on SENT, wait up to a minute, then check connectivity.
Scheduling issues
- Times are sent in UTC. Confirm your local time conversion is as expected.
- If devices are WAITING FOR TIME SYNC, scheduling may be safer than immediate start, or ensure NTP works.
Logs are empty
- Expand the time window or click “Display latest logs (4 hours)”.
- Verify the serial number and topic are correct for the device.
Permissions
- Only Global Admins and Organization Admins can control measurements. Users/Guests have read‑only access.
