Silla Prism — MQTT discovery script generator

1. Prism serial number

From the hello topic, e.g. Prism-A00006. Only letters, digits, _ and -.

MQTT base topic

Must match the topic base in the Silla app. A trailing / is added if missing.

2. Powerwall present Adds solar and house power sensors on energy_data/power_solar and energy_data/power_house.

3. Prism DUO (two ports) Duplicates port-scoped entities for cable 1 (left) and cable 2 (right).

Use UI Output starts at sequence: so you can paste it into the Home Assistant script editor.

Copy or download the script YAML.
Paste it into scripts.yaml (omit the top-level script: key if that file is already included), or merge it into configuration.yaml.
Reload scripts, then run the script once to publish discovery.
Do not use this together with the custom silla_prism integration on the same serial.

Fill the form to generate a script.

Example Optional automation to run the script when Home Assistant starts or MQTT comes online. Reference only — it is not included in copy or download.
