Node Maintenance Schedule

A simple maintenance schedule keeps your node reliable and avoids the surprise of a failed battery or corroded antenna during an emergency. Regular checks take 10-15 minutes per node and catch 90% ofmost common failure modes before they impact the network.early.

Safety note - work at height: Rooftop and mast work involves fall hazards. Use a properly footed ladder (maintain 3-point contact), avoid wet/icy roofs, never work at height alone, and consider binoculars or a camera pole for visual checks that do not require touching the node. If the node is on a tower, leave climbing to trained/certified climbers.

Monthly Checks (5 minutes)

  • App connection: Connect to your node and verify it responds. Check firmware version.
  • Battery level: For solar nodes, verify battery is charging (should be near full by midday). For USB-powered nodes, verify power is stable.
  • Neighbor count: Are you seeing the same neighbors as before? A suddenly empty neighbor list may indicate an antenna failure or a major change in the local network.
  • Channel utilization: ShouldKeep beutilization under 25%. If- consistentlythis overis the action threshold. Treat sustained readings above 15%, as an early warning to investigate why.before they climb toward 25%.

Quarterly Checks (15 minutes)

  • Visual inspection: For outdoor nodes - inspect the enclosure for water ingress, cracks, UV damage. Inspect antenna mount for rust or loosening. Check cable entry points for sealant integrity.
  • Firmware update: Check meshtastic.org for new stable releases. Update if more than 2 versions behind. Back up config before updating.
  • Configuration backup: Export config to file. Store in a cloud backup location.
  • Range check: Verify RSSI to 2-3 reference nodes. Compare to your baseline. A 5+ dB drop indicates antenna or cable degradation.

Annual Checks (30-60 minutes)

  • Battery capacity test: For solar systems, run a controlled capacity test: discharge at a known load to the batterymanufacturer's downcutoff deliberatelyvoltage (for example, about 10.5 V for a 12 V lead-acid battery), then recharge promptly. Avoid full discharges on lead-acid chemistry, as deep discharges measurably shorten its life.

Plan replacement when measured capacity drops belowto 70%about 80% of rated.rated - the standard end-of-life threshold - especially for nodes that must survive long winter nights.
  • Connector re-torque: Check all SMA/N connector connections and re-torque to specification. Use a calibrated torque wrench: ~5 in-lb (0.56 Nm) for brass SMA, ~8 in-lb (0.9 Nm) for stainless SMA; follow the manufacturer's spec for N connectors (typically ~15-20 in-lb / 1.7-2.3 Nm). Never use pliers; finger-tight is acceptable only for temporary bench setups.
  • Lightning protection inspection: Verify the coax surge arrestor is intact and the mast and arrestor ground/bond connections are tight and corrosion-free (NEC Article 810 requires a listed antenna discharge unit and mast grounding for outdoor antennas). If the install has no grounding at all, add it before the next storm season.
  • Re-weatherproof connectors: Remove old self-amalgamating tape, inspect connector for corrosion, reapply fresh tape.
  • Solar panel cleaning: Wipe panels with damp cloth. Bird droppings and dust accumulation can reduce output 5-15%.

Maintenance Log Template

Keep a simple maintenance log for each node:

Node: WH01-WestHillsRepeater

Maintenance Log:
2026-05-01: Quarterly check. RSSI to Summit -87dBm (baseline -85), within normal.
 Enclosure dry. Antenna secure. FW up to date.
2026-02-01: Quarterly check. Updated FW from 2.5.9 to 2.6.1.
 Backed up config. Checked solar: 13.8V at noon, good.
2025-11-01: Annual check. Replaced self-amalgamating tape on N connector.
