GREAT LOTUSInstall

Summary

Counts elements matching a selector or XPath through a Great Lotus developer action sent over MQTT. Use the target session’s remote port and provide a selector, XPath, or both; optionally wait for the response and include selected fields from incoming items.

Inputs

• Topic (required) — MQTT topic used to publish the request.
• Remote Port (required) — CDP port used to route the request to the intended client session; supports the virtual local session port 127001.
• QoS — MQTT delivery quality level: 0 (at most once), 1 (at least once), or 2 (exactly once). Defaults to 1.
• Include Input Items — When enabled, adds selected fields from incoming items to payload.inputItems. Defaults to false.
• Input Items Fields — Comma-separated field paths to copy from incoming items when Include Input Items is enabled; supports nested and indexed paths.
• Wait For Response — When enabled, waits for the MQTT response before returning output. Defaults to false.
• Response Timeout (sec) — Maximum response wait in seconds when waiting is enabled. Defaults to 60.
• Delay Next Step (ms) — Delay before continuing; runs after the response when waiting, or after publishing otherwise. Defaults to rand(200,1000).
• Target — Element selector, such as css=button. Defaults to empty.
• XPath — XPath expression for identifying elements, such as //button. Defaults to empty.

Output shape

An MQTT action response when waiting is enabled; otherwise no response body is awaited.

The action counts elements matching the supplied selector or XPath. The source-pack excerpt omits implementation bodies, so the exact response fields and behavior when neither locator is supplied are not shown.
