| Problem | Solution |
|---|---|
| Can't see ECOESS-ATS Wi-Fi network | Ensure the ATS is powered on. The access point broadcasts continuously. Move your laptop closer to the consumer unit. |
| "Cannot reach the ATS" | Verify you're connected to ECOESS-ATS (not your home Wi-Fi). Check the device password matches the one on the label. |
| Wi-Fi connection fails / times out | Double-check the Wi-Fi name and password (case-sensitive). Ensure the router is within range. Retry — the tool allows multiple attempts. |
| Tool doesn't open in browser | The tool starts a local web server. Check your firewall isn't blocking it. Try opening http://localhost:8080 manually. |
| Problem | Solution |
|---|---|
| Device shows "Offline" | Check your home internet is working. The ATS may have lost Wi-Fi — see Section 5 to reconnect. If recently installed, wait 1-2 minutes for it to come online. |
| Serial number rejected when claiming | Ensure you're entering the code exactly as printed (format: ECO-XXXX-XXXX). The code may have already been claimed — contact support. |
| Push notifications not working |
1. Check browser notification permissions (Settings → Notifications → allow myats.eco-ess.co.uk) 2. Ensure notifications are toggled on in the device card settings 3. Try disabling and re-enabling push notifications |
| Email notifications not arriving | Check your spam/junk folder. Ensure email notifications are toggled on in the device card settings. Emails are sent from noreply@eco-ess.co.uk. |
| Force Backup toggle not responding | The device must be online. Wait for the green "Online" indicator. If online but still not working, refresh the page. |
| Contactor states show "--" | The device hasn't reported status yet. Wait a moment after the device comes online. Toggling the Force Backup switch or a power event will update the readings. |
| Forgot password / locked out | Click "Forgot password?" on the login screen. A reset link will be sent to your email. |
The ATS has a status LED (Output 2) that mirrors the EPS contactor state:
| LED State | Meaning |
|---|---|
| ON | EPS contactor (S2) is closed — load is on backup power |
| OFF | EPS contactor (S2) is open — load is on grid (normal operation) |
