# Energy Site and Powerwall Data Issues

This FAQ addresses common questions about Energy Site data, including Powerwall status, null responses in the console, and grid connection monitoring.

## Why does the Live Status button show 'null' when I click it?

**Answer:**

A null response when clicking the Live Status button in the Teslemetry console is typically a temporary server-side issue that will either resolve itself, or can be resolved by logging in again.

**Solution:**

1. Go to [teslemetry.com/login](https://teslemetry.com/login)
2. Complete the login process (this refreshes your authentication)
3. Return to the console and try the Live Status button again

This issue does not necessarily indicate a problem with your Powerwall or Tesla account, but may be a temporarily issue with Tesla's service.

## What does island_status mean for my Powerwall?

**Answer:**

The `island_status` field indicates whether your Powerwall is connected to the electrical grid or operating independently (islanded).

**Values and their meanings:**

| Value | Meaning |
| ---- |
| `on_grid` | Powerwall is connected to the grid and operating normally |
| `off_grid` | Powerwall has disconnected from the grid (islanded mode) |
| `off_grid_intentional` | You manually took the system off-grid |
| `off_grid_unintentional` | System disconnected due to grid instability or outage |
| `unavailable` | Status cannot be determined (exclude this in automations) |

**Using island_status in Home Assistant automations:**

If you want to trigger automations when you lose grid connection:
* Trigger when `island_status` is NOT "on_grid"
* **Important:** Exclude the "unavailable" state from your triggers

## Do Energy sites require explicit permission during Tesla authorization?

**Answer:**

Yes. When you first connect your Tesla account to Teslemetry, you must explicitly grant permission for energy products.

**Required scopes:**
* **Energy Product Information**: Allows querying data from Tesla energy products
* **Energy Product Commands**: Allows sending commands to Tesla energy products

If you did not enable these scopes during initial setup, your energy sites will not appear in Teslemetry.

**To add energy permissions:**
1. Visit auth.tesla.com to modify your Teslemetry permissions
2. Enable the Energy Product Information and Energy Product Commands scopes
3. Log in again at [teslemetry.com/login](https://teslemetry.com/login)

## Can unused energy sites cause Home Assistant integration errors?

**Answer:**

Yes. If you have energy sites associated with your Tesla account that you do not actively use or that return incomplete data, they can cause errors in the Home Assistant integration.

**How to resolve:**
1. Check your [Teslemetry console](https://teslemetry.com/console) to see all energy sites linked to your account
2. If you have sites you do not use, consider excluding them from your subscription
