Thanks so much.
I love sharptools and definitely prefer it over the native home assistant dashboards. The only exception is for Sonos. Their card in HA is really nice.
That dashboard is embed of a homeassistant lovelace page. It took a few steps to be able to embed a page from homeassitant, but this thread is what helped me out : Google Chrome - Mixed Content - Media Not Showing
I then made a dashboard in homeassistnat using this card with homeassitant. It’s super useful, responsive, and handles grouping and ungrouping really well. Reach out if you have any questions, as I really enjoyed making this.
