# fppd/condition/preview

`GET /api/fppd/condition/preview`

Preview a single If/Conditional Check leaf's current raw value - the same lookup evaluate() uses internally (Variable/Expression/Setting/Time/MQTT/ GPIO Pin/Sensor/Sun), before any comparator/Value is applied. Backs the If condition editor's "Show Current Value" button, so picking the right Value to compare against isn't guesswork.

## Query parameters

- `source` string
- `name` string

## Response `200`

{"found": true, "value": "..."} or {"found": false} if the source/name doesn't currently resolve.
