output dynamic text (local temperature) to screensaver?

Hi all,

I would like to be able to show temperatures from my home sensors on my SB radios' screens. I've read that weather screensavers are available via applets like SuperDateTime, but they all seem to only get readings from remote APIs.
So my question is: can I send the temperature from my home assistant server and show it on the squeezebox display in some way?

Thanks in advance :-)
