My setup is similar, though my doorbells are simple wired pushes switching central mains powered transmitters with receivers scattered around the house to help my rather deaf wife, but it hasn’t been entirely maintenance free in the longer term. My receivers lasted around 8-10 years before gradually expiring as the mains-dropping capacitors steadily failed. Not a difficult or expensive repair though - just as well as the receivers are discontinued now. I’ve never measured the overall consumption though I estimate it’s around 10 watts but it does the job.
