# Check your plants

The daily portfolio check lists Plants with low PR, low availability, offline devices, or active alarms. It reads device detail for at most five flagged Plants.

## Start the check

Ask this question in your AI tool:

```
Which of my Plants have a problem today, such as low PR, low availability, offline devices, or active alarms? Name the offline devices at each Plant with a problem.
```

You can also select `daily-portfolio-check` as a prompt. See [Guided checks](https://ai.solarsens.co/docs/concepts/skills.md).

If you do not give a date, the check uses today in the time zone of each Plant. The date sets the seven-day yield window. Device and alarm status are live. A past date does not show past device status.

## Limits

Not checked: work orders, site weather.

Read only when you ask: alarm detail.

Missing values are "no reported value", never zero. For weak strings, use [Review strings](https://ai.solarsens.co/docs/guides/string-review.md). For low PR, use [Review performance](https://ai.solarsens.co/docs/guides/plant-analysis.md#run-the-plant-performance-review).
