Handoff: DHCP pool shrink to .61–.99 — prep done, blocked on two device statics

Continues: 2026-10-22-ha-lost-ipv4.md

Done

• 2026-10-26: projector had drifted .149 → .103 despite its GUI-set Omada reservation. HA /config/configuration.yaml pjlink host: → .103 (backup in /config/.backup/), entity live. network_inventory.md + ROUTER.md updated (backups in ~/bin/.backup/).
• 2026-10-28 pre-change audit (backups: ~/bin/network-tools/.backup/omada-lan-networks-*.json, omada-insight-clients-pre-pool-shrink-*.json, client-detail-pre-pool-shrink.tsv):
  • Every running PVE guest is static. DHCP/guest-configured ones (CT 106, VMs 607/116/100/131) are stopped; VM 706 (HA) is static inside HAOS.
  • Only static inside .60–.99: CT 693 romm @ .60 → Seth chose pool .61–.99 (not .60–.99).
  • .60–.99 already holds ~15 DHCP clients (IoT, XP-7100 .96, LG TV wired now .81). Outside-pool DHCP that will renumber: .55 ESP, .59 Nest cam, .101 TV wifi, .102 Pixel-9, .176, .183 vjtop, .184 printer, .103 projector.

Blocked on Seth (sequence: statics first, then pool)

1. Projector: on-screen menu → network → DHCP off, IP 192.168.0.103/24, gw .1, DNS .153. Its web UI is a dead Java applet (ProjectorView X500U) with no IP config.
2. Receipt printer TM-m30: static .184. EpsonNet Config at https://192.168.0.184 needs HTTP auth (creds unknown; Epson defaults are user epson / pw serial number or epson). Hard-coded .184 in hal/backend/printer.py, hermes/.../notify.py, mcp-pos-print/server.py.

Then

• Verify both answer at their IPs after a power cycle (PJLink %1POWR, TCP 9100).
• Change pool via internal API PATCH sites/{SITE}/setting/lan/networks/{netId} (dhcpSettings.ipRangePool / ipaddrStart/End → .61/.99) — the full network object is in the backup JSON; read the GET shape first. Verify with GET, then watch for renumbered clients over ~2h. Update ROUTER.md "DHCP range".

Side finding

• ~/.ssh/config seth-pi → 192.168.0.102, but Omada shows .102 = Pixel-9-Pro. Alias is stale.
