+# 128 — `trmnl`
+
+Self-hosted middleware for TRMNL e-ink plugins. TRMNL cloud polls it; it fetches/shapes live data into JSON the plugin's Liquid template renders.
+
+## At a glance
+- **Hostname:** `trmnl`
+- **IP:** `192.168.8.211`
+- **Privilege:** unprivileged
+- **Resources:** 1 core / 768 MiB RAM / 8 GiB rootfs (Debian 13)
+- **Mounts:** none
+- **Public hostname:** `trmnl.hubris.network` (via [VPS ingress](../infrastructure/ingress.md))
+
+## Role
+Runs one FastAPI aggregator (`server.app:app`, port 9851) that mounts a router per plugin from the `dtoro/terminalito` repo. First consumer: `munich-home` (`/munich-home/dashboard`) — weather (Open-Meteo), MVG transit, Google Calendar, plus server-side Kita/quote logic. Talks out to the public internet for those APIs; TRMNL cloud polls it inbound every 15 min. Bearer-token gated (`TRMNL_POLL_TOKEN`); `/health` is open.
+
+## Service / port map
+| Service | Listen | Notes |
+|---------|--------|-------|
+| `trmnl-plugins` | `0.0.0.0:9851` | uvicorn aggregator; `EnvironmentFile=/etc/trmnl-plugins/env` |
+
+## Storage / config paths
+- `/opt/terminalito` — git checkout (origin = internal gitea `http://192.168.8.121:3000/dtoro/terminalito.git`)
+- `/opt/terminalito/server/.venv` — venv
+- `/etc/trmnl-plugins/env` — `TRMNL_POLL_TOKEN` (+ Google/MVG creds once enrolled)
+- `/etc/systemd/system/trmnl-plugins.service`
+
+## Auto-deploy
+Wired — [auto-deploy](../infrastructure/auto-deploy.md) Shape B, webhook id 12 on `dtoro/terminalito` → `http://192.168.8.211:9797/deploy` (`terminalito-deploy.service`). Push to `main` → `server/deploy/deploy.sh` (`git pull` + pip + reinstall units + restart `trmnl-plugins`). Secret `/etc/terminalito-deploy/secret`; git creds `/etc/terminalito-deploy/git-credentials` wired as a repo-local `credential.helper`. Manual: `pct exec 128 -- /opt/terminalito/server/deploy/deploy.sh`.
+
+## Secrets
+Not yet SOPS-enrolled. The poll token is set directly in `/etc/trmnl-plugins/env`. Google Calendar + MVG creds are pending: enroll via `homelab client add trmnl` + bootstrap, add `secrets/trmnl-oauth.yaml`, then `server/deploy/render-env.sh` builds the env from `homelab secret trmnl-oauth`. Until then calendar/transit cards degrade to empty; weather works.

+## Changelog
+### 2026-06-24 — auto-deploy + LAN DNS wired
+Gitea Shape-B deploy pipeline (webhook id 12, `:9797`) — push to `dtoro/terminalito` redeploys; verified end-to-end. Technitium A record `trmnl.hubris.network → 192.168.8.175` added on [dns (107)](107-dns.md) (propagated to the NetBird managed zone via dns-sync), so LAN clients take the short path through [Caddy (121)](121-caddy.md). See [auto-deploy](../infrastructure/auto-deploy.md).
+
+### 2026-06-24 — public path live
+Verified end-to-end from the internet: `https://trmnl.hubris.network/munich-home/dashboard` → 200 with token, 401 without; `/health` 200. The provision-time outage was the netbird `home-lab-network` (192.168.8.0/24) route having no active routing peer — the **mac-mini routing peer's netbird daemon was down** (artifacto/blog were 504 too). Bringing netbird up on mac-mini restored the route; the edge recovered with no config change. See [ingress](../infrastructure/ingress.md) / [mesh](../infrastructure/mesh.md).
+
+### 2026-06-24 — provisioned
+LXC 128 created (Debian 13, unprivileged, `192.168.8.211`). Deployed `trmnl-plugins.service` on :9851 from `dtoro/terminalito`. Caddy block added (`dtoro/caddy-conf`) + LE cert via IONOS DNS-01; verified `/health` 200 and `/munich-home/dashboard` (live weather) through Caddy. Cert mirrored to VPS (`trmnl.fullchain.crt`/`trmnl.privkey.key`) + traefik router `trmnl-public` → `192.168.8.211:9851` added to `/opt/traefik-dynamic.yaml`. **Public path pending**: VPS↔home netbird route was down at provision time (`No networks available`, 3/6 peers — artifacto/blog also 504); resolves when the mesh route recovers. **LAN pending**: Technitium A record not yet added. Not SOPS-enrolled; Google/MVG creds pending.
