+# 🦞 OpenClaw Watchdog — Krilly's Fork
+
+**Original:** [jlgrimes/openclaw-watchdog](https://github.com/jlgrimes/openclaw-watchdog)  
+**Modified by:** Krilly the Crab 🦀
+
+## What's Different?
+
+This fork adds **Telegram** and **Gotify** notifications alongside (or instead of) Discord.
+
+| Feature | Original | This Fork |
+|---------|----------|-----------|
+| Discord alerts | ✅ | ✅ (optional) |
+| Telegram alerts | ❌ | ✅ |
+| Gotify alerts | ❌ | ✅ |
+| Multi-channel | ❌ | ✅ (simultaneous) |
+
+## Quick Install
+
+```bash
+git clone https://github.com/jlgrimes/openclaw-watchdog.git
+cd openclaw-watchdog
+chmod +x setup.sh watchdog.sh
+./setup.sh
+```
+
+The installer will ask for:
+- Telegram Bot Token
+- Gotify Token
+- Gotify URL (defaults to your setup)
+
+## Configuration
+
+Edit `~/.openclaw/watchdog.env`:
+
+```bash
+# Required for Telegram
+TELEGRAM_BOT_TOKEN=your_bot_token_here
+TELEGRAM_CHAT=1793951355
+
+# Required for Gotify
+GOTIFY_URL=http://runtipi.kangaroo-eel.ts.net:8129
+GOTIFY_TOKEN=your_gotify_token_here
+
+# Optional: Legacy Discord
+DISCORD_CHANNEL_ID=
+DISCORD_BOT_TOKEN=
+```
+
+All three can work simultaneously — get alerts wherever you want!
+
+## How It Works
+
+Same great watchdog behavior from the original:
+
+1. **Health checks** every 30s (configurable)
+2. **Stage 1:** Simple restart on first failure
+3. **Stage 2:** Config rollback + restart on second failure
+4. **Stage 3:** SOS alert after 3+ failures
+5. **Recovery:** Notification when gateway comes back
+
+But now alerts go to **Telegram** and **Gotify** too!
+
+## Managing the Service
+
+```bash
+sudo systemctl status openclaw-watchdog   # Check status
+sudo systemctl restart openclaw-watchdog  # Restart
+sudo systemctl stop openclaw-watchdog     # Stop
+tail -f ~/.openclaw/watchdog.log          # View logs
+```
+
+## Test Notifications
+
+```bash
+export TELEGRAM_BOT_TOKEN="your_token"
+export TELEGRAM_CHAT="1793951355"
+export GOTIFY_TOKEN="your_token"
+
+# Source the functions and test
+source ~/.openclaw/watchdog.sh
+telegram_send "🦀 Test message from Krilly!"
+gotify_send "Test" "🦀 Test message from Krilly!" 5
+```

+# 🦞 openclaw-watchdog
+
+A standalone watchdog service for [OpenClaw](https://openclaw.dev) that monitors the gateway, auto-recovers from crashes, and sends Discord alerts when things go sideways.
+
+## What It Does
+
+- **Health monitoring** — Polls the gateway health endpoint at a configurable interval
+- **Auto-restart** — Restarts the gateway on first failure detection
+- **Config rollback** — Reverts to last-known-good config if a simple restart doesn't work
+- **Discord SOS alerts** — Sends a detailed alert with SSH instructions when all recovery fails
+- **Recovery notifications** — Lets you know when the gateway comes back online
+- **No spam** — Only alerts once per incident
+
+## Recovery Flow
+
+```
+Health check fails
+       │
+       ▼
+  ┌─────────────┐
+  │ Stage 1:    │──→ Simple restart
+  │ Restart     │
+  └──────┬──────┘
+         │ still failing
+         ▼
+  ┌─────────────┐
+  │ Stage 2:    │──→ Revert config to last-known-good + restart
+  │ Rollback    │
+  └──────┬──────┘
+         │ still failing
+         ▼
+  ┌─────────────┐
+  │ Stage 3:    │──→ Discord SOS with hostname & SSH instructions
+  │ SOS Alert   │
+  └─────────────┘
+```
+
+When the gateway recovers at any point, a ✅ recovery message is sent.
+
+## Prerequisites
+
+- [OpenClaw](https://openclaw.dev) installed with `openclaw` CLI available
+- Linux with systemd
+- `curl` and `jq`
+- Discord bot token (optional, for alerts)
+
+## Quick Install
+
+```bash
+git clone https://github.com/jlgrimes/openclaw-watchdog.git
+cd openclaw-watchdog
+chmod +x setup.sh watchdog.sh
+./setup.sh
+```
+
+The installer will:
+1. Copy `watchdog.sh` to `~/.openclaw/`
+2. Create a config file at `~/.openclaw/watchdog.env`
+3. Set up and start a systemd service
+
+## Configuration
+
+All settings live in `~/.openclaw/watchdog.env` (created by the installer):
+
+| Variable | Default | Description |
+|---|---|---|
+| `HEALTH_URL` | `http://localhost:3000/health` | Gateway health endpoint |
+| `CHECK_INTERVAL` | `30` | Seconds between health checks |
+| `FAIL_THRESHOLD` | `3` | Consecutive failures before SOS |
+| `OPENCLAW_CONFIG_PATH` | `~/.openclaw/config.yaml` | Path to OpenClaw config |
+| `DISCORD_CHANNEL_ID` | *(none)* | Discord channel for alerts |
+| `DISCORD_BOT_TOKEN` | *(none)* | Discord bot token for alerts |
+
+After editing, restart the service:
+
+```bash
+sudo systemctl restart openclaw-watchdog
+```
+
+## Manual Usage
+
+You can also run the watchdog directly:
+
+```bash
+export DISCORD_BOT_TOKEN="your-token"
+export DISCORD_CHANNEL_ID="your-channel-id"
+./watchdog.sh
+```
+
+## Managing the Service
+
+```bash
+sudo systemctl status openclaw-watchdog    # Check status
+sudo systemctl restart openclaw-watchdog   # Restart
+sudo systemctl stop openclaw-watchdog      # Stop
+tail -f ~/.openclaw/watchdog.log           # View logs
+```
