Apple Homepod turns off after a while

Hello everyone, I use my Homepod in Home Assistant to use NodeRed to play TTS and sounds for certain events (when and for what exactly would be beyond the scope now :D) If I haven’t been in the dashboard for a few days, my Homepod is very often switched off (see picture). Then of course my programming no longer works and I have to switch the Homepod on again in HA, which is pretty annoying… Why is that? Is there anything I can change to make the Homepod stay on permanently, or is there a command in NodeRed that you can insert that turns the Homepod on?
