SeRA

SeRA (Secure Remote Access) opens secure, time-boxed tunnels to your field devices for remote maintenance.

SeRA lets you reach a station's own web interface from anywhere, without a site visit or a VPN. You start a session for one device, Live3 gives you a username and a one-time code, and the session closes by itself when its timeout runs out. Nothing stays open in between: a station can only be reached while a session is running.

How to get there. Choose SeRA in the left navigation.

Key areas

AreaWhat it does
SearchFind a device by name, serial number or model.
Filter chipsTotal, SeRA active, online and SeRA-capable. Click a chip to show only those devices; click it again to clear.
RefreshThe list refreshes itself every few seconds; click to check now.
Device listEach row shows the device, its model, whether it is connected, its session timeout and its status. Sort by status to bring active sessions to the top.
TimeoutHow long a session lasts, counted from when it started (activity does not extend it): 5, 10, 15 or 30 minutes, or 1, 2, 4, 8, 12 or 24 hours. Changing it during a session moves the session's end time, and Live3 tells you when it now ends. Changing it with no session running applies to the next one.
Enable and StopEnable starts a session. While one runs, the row shows the time left and a Stop button.
Session windowClick an active row to open it: the time left, whether the station is online, who opened the session, the username and code (each with a copy button), and Open Web UI.

Common tasks

Open a remote session to a device

  1. Find the device. Its status must show it as connected; a station that is offline cannot start a session.
  2. Choose a timeout. Pick the shortest that covers the job.
  3. Click Enable. The session window opens.
  4. Click Open Web UI. The device's page opens in a new tab and asks for a username and code. Copy both from the session window.

Share access with Aeron support

  1. Start a session as above.
  2. Send the username and code to the support engineer over a secure channel, not in a public chat or ticket.
  3. Stop the session when they are done, or let it time out.

Anyone with access to the station can read the code again for as long as the session runs, so you can reopen the session window if you closed it.

End a session early

  1. Find the device's row and click Stop, then confirm.
  2. The station must be online to receive the stop. If it has gone offline, the session ends at its timeout, or you can stop it once the station is back.

A device shows "Firmware upgrade required" or "Remote access not set up"

The device cannot run SeRA yet. Click the badge to email Aeron support with the device's details filled in, and they will help upgrade or set it up.

Who can use SeRA. Only the station's owner can start a session: an Owner of the station's organization, or someone with an admin allocation on it (or its Site Manager). Technicians can see the list, but the controls stay disabled. A session someone else opened can only be stopped or changed by them or by the station's owner. Aeron staff cannot start a session on your devices. Every session that is enabled or disabled is recorded in the Audit Log.
