If you love your family and want them to go to heaven, advise them to follow Islam by following Tauheed, make them pray, fast, ban Haraam acts at home like TV, music, movies etc.

“The believers, men and women, are allies (helpers, supporters, friends, protectors) of one another, they enjoin (on the people) Al-Ma’ruf (i.e. Islamic Monotheism and all that Islam orders one to do), and forbid (people) from Al-Munkar (i.e. polytheism and disbelief of all kinds, and all that Islam has forbidden); they perform As-Salat (Iqamat-as-Salat) and give the Zakat, and obey Allah and His Messenger. Allah will have His Mercy on them. Surely Allah is All-Mighty, All-Wise.”
(Quran 9:71)
