# Home Assistant Performance Fix & Infrastructure Migration
|
||
|
||
## Problem Summary
|
||
|
||
Home Assistant at `ha.hideawaygaming.com.au` (HAOS 2026.5.3) periodically becomes unresponsive. Because critical infrastructure services (AdGuard DNS, Tailscale VPN, Guacamole RDP) all run as HA add-ons inside the same VM, any HA freeze causes house-wide network and access failures.
|
||
|
||
### Root Causes Identified
|
||
|
||
| Issue | Impact |
|
||
|-------|--------|
|
||
| Memory at 87% (4.45 GB) | VM swaps under load → unresponsive |
|
||
| 2,330 entities, 775 unavailable (33%) | Wasted memory and CPU tracking stale entities |
|
||
| ~1,007 state changes/hour (16.8/min) | Recorder DB I/O bottleneck |
|
||
| browser_mod: 228 entities (200 stale) | Biggest source of entity bloat |
|
||
| iCloud3: 1,000+ state changes/4hr | Aggressive polling floods state machine |
|
||
| Frigate occupancy flapping ~97x/hr | Detection zones too sensitive |
|
||
| 3 time sensors × 60 changes/hr = 720/hr | Pointless recorder writes |
|
||
| Guacamole using 25% CPU / 9% RAM | Heavy add-on consuming HA resources |
|
||
| AdGuard (network DNS) inside HA | Single point of failure |
|
||
|

|
||
|
||
## Fix Plan (Priority Order)
|
||
|
||
### Phase 1: Immediate — Recorder Exclude (10 minutes)
|
||
|
||
Apply `recorder_exclude.yaml` to stop recording high-churn, low-value entities.
|
||
|
||
**Steps:**
|
||
|
||
1. SSH into HAOS or use the File Editor add-on
|
||
2. Open `/config/configuration.yaml`
|
||
3. If you already have a `recorder:` section, merge the excludes from `recorder_exclude.yaml` into it
|
||
4. If you don't have one, copy the entire contents of `recorder_exclude.yaml` into `configuration.yaml`
|
||
5. Restart HA: Settings → System → Restart
|
||
|
||
**Expected impact:** ~2,500 fewer state changes recorded per hour, significant reduction in disk I/O and memory usage.
|
||
|
||
### Phase 2: Immediate — Entity Cleanup (20 minutes)
|
||
|
||
**browser_mod stale sessions:**
|
||
1. Go to Developer Tools → Services
|
||
2. For each stale browser_mod entity, call the service to unregister it
|
||
3. Alternatively: Settings → Devices & Services → browser_mod → Remove stale device entries
|
||
4. Target: reduce from 228 to ~20-30 active entities
|
||
|
||
**Plex media player cleanup:**
|
||
1. Settings → Devices & Services → Plex
|
||
2. Click through each device — delete any showing as "Unavailable"
|
||
3. Target: reduce from 59 to ~5-10 active clients
|
||
|
||
**Pioneer VSX-832 duplicates:**
|
||
1. Settings → Devices & Services → Onkyo
|
||
2. You should see multiple "Pioneer VSX-832" devices
|
||
3. Keep only the working one (likely the one showing state "off" or "on")
|
||
4. Delete the rest (showing "unavailable")
|
||
5. Target: reduce from 7 to 1-2 entities
|
||
|
||
**F1 Sensor (off-season):**
|
||
1. Settings → Devices & Services → F1 Sensor
|
||
2. Consider disabling the integration during off-season
|
||
3. Or leave it — the recorder exclude will prevent it writing history
|
||
4. 76 entities, 42 currently unavailable
|
||
|
||
### Phase 3: Tune Noisy Integrations (15 minutes)
|
||
|
||
**iCloud3 — reduce polling frequency:**
|
||
1. iCloud3 config (via HA integrations or config file)
|
||
2. Increase `inzone_interval` from default to 30-60 minutes
|
||
3. Increase general polling interval
|
||
4. This alone cuts ~1,000 state changes per 4 hours
|
||
|
||
**Frigate — fix driveway zone flapping:**
|
||
1. In your Frigate config, for the driveway camera zones:
|
||
- Increase `min_area` on car detection (currently triggering on shadows/reflections)
|
||
- Add `inactivity_timeout: 30` to prevent rapid on/off toggling
|
||
- Consider disabling `cat` and `dog` detection on the driveway if not needed
|
||
2. The driveway_car_occupancy and driveway_pavement_car_occupancy are toggling ~97x/hour each
|
||
|
||
**Time sensors — remove duplicates:**
|
||
1. If `sensor.time`, `sensor.time_2`, and `sensor.date_time` are defined in `configuration.yaml` under `sensor:` → `platform: time_date`, remove the duplicates
|
||
2. Keep only one if needed for automations, or rely on HA's built-in `now()` in templates instead
|
||
|
||
**UpdatePowerUsageFast automation:**
|
||
1. Settings → Automations → UpdatePowerUsageFast
|
||
2. Change the time pattern trigger from every 1 minute to every 5 minutes
|
||
3. Cuts 192 automation runs per hour
|
||
|
||
### Phase 4: Increase VM Memory (5 minutes)
|
||
|
||
On the Proxmox host:
|
||
1. Shut down the HAOS VM (or hot-plug if supported)
|
||
2. Increase RAM from current allocation to **8 GB**
|
||
3. HAL-HOST has 134 GB total with 78% used — there's headroom
|
||
4. Start the VM
|
||
|
||
### Phase 5: Migrate AdGuard to LXC (30 minutes)
|
||
|
||
**This is the most important architectural change.** Network DNS must not depend on HA stability.
|
||
|
||
See `setup-adguard-lxc.sh` — run on the Proxmox host.
|
||
|
||
```bash
|
||
# Copy to Proxmox host
|
||
scp setup-adguard-lxc.sh root@10.0.0.x:/root/
|
||
|
||
# Run it (default CT ID 120, or pass custom)
|
||
ssh root@10.0.0.x
|
||
chmod +x /root/setup-adguard-lxc.sh
|
||
/root/setup-adguard-lxc.sh 120
|
||
```
|
||
|
||
**Post-setup migration:**
|
||
1. Access new AdGuard at `http://10.0.0.53:80`
|
||
2. Complete the setup wizard
|
||
3. Export config from HA's AdGuard add-on web UI and import to new instance
|
||
4. Migrate filter lists, client settings, parental controls, DNS rewrites
|
||
5. Test: `nslookup google.com 10.0.0.53`
|
||
6. Update OPNsense DHCP: change DNS from `10.0.0.55` to `10.0.0.53`
|
||
7. Wait 24 hours, confirm stability
|
||
8. Stop HA AdGuard add-on
|
||
9. Optionally re-add HA AdGuard integration pointing to `10.0.0.53` for dashboard stats
|
||
|
||
**NPM reverse proxy (optional):**
|
||
- Add proxy host in NPM (10.0.0.54):
|
||
- Domain: `adguard.hideawaygaming.com.au`
|
||
- Forward: `http://10.0.0.53:80`
|
||
- SSL via Let's Encrypt
|
||
|
||
### Phase 6: Migrate Guacamole to LXC (30 minutes)
|
||
|
||
See `setup-guacamole-lxc.sh` — run on the Proxmox host.
|
||
|
||
```bash
|
||
scp setup-guacamole-lxc.sh root@10.0.0.x:/root/
|
||
ssh root@10.0.0.x
|
||
chmod +x /root/setup-guacamole-lxc.sh
|
||
/root/setup-guacamole-lxc.sh 121
|
||
```
|
||
|
||
**Post-setup migration:**
|
||
1. Access new Guacamole at `http://10.0.0.52:8080/guacamole/`
|
||
2. Login with `guacadmin` / `guacadmin` — **change password immediately**
|
||
3. Re-create your RDP connections (hostname, port 3389, credentials)
|
||
4. Re-create any user accounts
|
||
5. Set up NPM reverse proxy with WebSocket support
|
||
6. Test all RDP connections
|
||
7. Stop HA Guacamole add-on
|
||
|
||
**NPM reverse proxy:**
|
||
- Domain: `guac.hideawaygaming.com.au`
|
||
- Forward: `http://10.0.0.52:8080`
|
||
- Custom location: `/guacamole/`
|
||
- **Enable WebSocket support** (critical for RDP streaming)
|

|
||
```
|
||
|
||
Tailscale stays in HA since it's lightweight and tightly integrated with HA's remote access. AdGuard and Guacamole are now independent — HA can restart without taking down DNS or RDP access.
