Has anyone cracked using the BT Home Hub to provide presence detection? I would love to be able to use this to e.g. note when guest devices are in the house to suspend some routines i.e. my brother-in-law has come to stay.
Home Assistant have cracked this https://home-assistant.io/components/device_tracker.bt_home_hub_5/ so it is ‘possible’.
BT are the largest ISP in the UK by far, so there’ll be lots of users interested in this.
