Creates a light group combining mpho_lamb and hloni_lamb, and sets up
four daily automations: on at sunset/18:00 (full cool white), warm dim
at 20:30, hloni off at 22:00, mpho off at 06:00 — all with fade transitions.
setup-homeassistant.sh now deploys automations.yaml alongside configuration.yaml.
head -1 always returned the first (empty) match when a key existed with
an empty value in .env, causing auto-generated secrets like
NODE_RED_CREDENTIAL_SECRET to be ignored during substitution.
- Replace GENERATE placeholders with actual pan_id/network_key values
- Add known devices with friendly names to template
- Setup script now skips zigbee2mqtt config copy if file already exists,
preventing configuration-adapter mismatch on redeploy
