+### Firmware Version Tracking
+
+The system automatically checks for latest firmware versions daily (2 AM dev, 4 AM prod). To manually trigger a firmware check:
+
+```bash
+# Start IEx console
+iex -S mix phx.server
+
+# Manually trigger firmware version fetch
+Oban.insert(Towerops.Workers.FirmwareVersionFetcherWorker.new(%{}))
+```
+
+The worker will:
+1. Fetch the latest MikroTik RouterOS version from RSS feed
+2. Store version information in the database
+3. Enable firmware update indicators on device detail pages
+
+Check the logs for fetch results:
+```elixir
+# View recent Oban jobs
+Towerops.Repo.all(Oban.Job) |> Enum.take(5)
+```
