I have some code I obtained from a pentester related to some potential areas we can use to control ultraloq ble locks. However I’m not a python expert for home assistant or c++ for esphome components.
I started a discord server as well for discussion and research into ultraloq locks and hopefully testing a local component to control them through Bluetooth using esphome Bluetooth proxies or home assistant Bluetooth.
