Seura UB4 Series Control Spec

Summary

IP-controlled outdoor TV series supporting TCP over HTTP (port 3000). Compatible with multiple Seura Pro and UB4 models. Control via JSON commands over HTTP POST requests; responses include power state, input, channel, volume, mute, and device info (model, serial, firmware, runtime).

Transport

protocols:
  - tcp
  - http
addressing:
  port: 3000
  base_url: /  # explicit POST / HTTP/1.1 request path
auth:

Traits

- powerable  # power on/off/toggle commands present
- queryable  # status query commands present (PWD:?, CHA:?, INP:?, VOL:?, MUT:?)
- routable   # input selection commands present (INP:0-7)
- levelable  # volume control commands present (VOL:+-/XX)

Notes

Static IP requirement: Power cycle the display after entering static IP address information to ensure proper control system operation.

HTTP request format: POST to / with JSON body {"command": "<cmd>", "id": <optional-int>}. Response includes result status ("SUCCESS", "INVALID VALUE", "INVALID JSON", "UPDATE") and state object with power, input, channel, volume, mute fields. Info object contains model, serial, firmware version, and runtime hours.
