The missing playback signal
Why doesn’t HomePod scrobble to Last.fm?
Most Mac scrobblers watch a local player. When HomePod owns playback, that local signal can be missing. Playstate connects to supported HomePods on the same network so it can follow the speaker instead.

The Mac is no longer the player
Starting music from Siri or another device can leave Music.app on your Mac with no useful now-playing state. A scrobbler that only watches the Mac has nothing to submit.
Playstate follows the HomePod
Playstate discovers supported HomePods locally, reads the current playback state, and applies normal Last.fm scrobble timing from your Mac.
Your network may differ
Speaker firmware, routing, and network isolation can affect discovery. That is why the complete app is free for your first 30 minutes of listening: confirm it follows your HomePod, then buy once for US$24.
Try it on your Mac
