So what i understand now is that I need to run a node by myself -which is still foreign to me- to do it.

I like to close everything off when i leave the home and shut off internet when sleeping, so chance is I need to do that 'one time payment' again and again?
Meaning this is not the way for me and better I do a subscription way or find how to use something like coinoswallet (npub1h2q…w8ch) ?
