Thanks for the pointer to using a temporary template to generate a yaml snippet. I can use that for thermal_comfort, but unfortunately mold_risk_index gives me an error: "The mold_risk_index integration does not support YAML setup, please remove it from your configuration"
I will look into using the API to create missing entities (but it looks like this is not perfect:
- not editable through the UI: REST API and unique id
- not removable: How can I delete an entity via API call?
