Store & Forward ​

New in 4.0 (Phase 0)

MeshMonitor is now a Store & Forward client. It recognizes S&F server nodes on your mesh and can request history from them. Full server functionality remains on the node itself.

What is Store & Forward? ​

Meshtastic's Store & Forward module lets a powered node (usually a mains-powered repeater) cache messages while recipients are offline, then replay them on request. Nodes acting as S&F servers are marked as is_store_forward_server in their device metadata.

What MeshMonitor does ​

  • Detects S&F servers — nodes with the S&F server flag are visually marked in the Nodes list and on the map
  • Labels relayed messages — messages that arrived via_store_forward are tagged in the message history so you can distinguish them from direct traffic
  • Receives replays — when an S&F server pushes ROUTER_TEXT_DIRECT / ROUTER_TEXT_BROADCAST history to the mesh, MeshMonitor ingests those messages and tags them accordingly
  • Preserves S&F metadata across upgrades — two new database fields (is_store_forward_server, via_store_forward) were added in migrations 034 and 035

Passive client only

MeshMonitor does not actively request history from S&F servers — it reacts to replays the server decides to push. Enabling S&F history requests (a CLIENT_HISTORY message) is on the roadmap.

When it helps ​

  • Intermittent coverage — messages you missed while out of range are still retrievable
  • Shared repeaters — a community repeater acts as a message buffer for the whole mesh
  • Debugging — spot messages that transited an S&F peer instead of direct RF

Configuration ​

Store & Forward itself is configured on the device (firmware config, not MeshMonitor). Use the device configuration UI or the Meshtastic mobile app to:

  1. Enable the Store & Forward module on the node
  2. Choose whether it runs as a server, client, or both
  3. Tune retention (history entries, record time window)

Once the node reports S&F capability to MeshMonitor (it comes through as part of device info), MeshMonitor's S&F awareness activates automatically — no per-source configuration needed.
