You can try it. Give the AI the base code and tell it to use the rejectattr function when updating the code to exclude labels. See what happens.

Now I'm a hardware guy and know diddly about code but this is working to reject labels in one of my mushroom cards. Is that remotely relevant? secondary: |- {{ states.light | rejectattr('entity_id', 'in', label_entities('Group')) | rejectattr('entity_id', 'in', label_entities('Dummylight')) | selectattr('state', 'eq', 'on') | list | count }} — Reply to this email directly, view it on GitHub <https://gist.github.com/Ltek/0c9cecf632b9c32915130680d834bcf7#gistcomment-5498206> or unsubscribe <https://github.com/notifications/unsubscribe-auth/AAMNFMQRWARHMS54BAMFWWD2U2BATBFKMF2HI4TJMJ2XIZLTSKBKK5TBNR2WLJDUOJ2WLJDOMFWWLO3UNBZGKYLEL5YGC4TUNFRWS4DBNZ2F6YLDORUXM2LUPGBKK5TBNR2WLJDHNFZXJJDOMFWWLK3UNBZGKYLEL52HS4DFVRZXKYTKMVRXIX3UPFYGLK2HNFZXIQ3PNVWWK3TUUZ2G64DJMNZZDAVEOR4XAZNEM5UXG5FFOZQWY5LFVEYTGNRYGI4DANJZU52HE2LHM5SXFJTDOJSWC5DF> .
