Hi,
I have a rpi3 b+ running hass.io and i’m wondering if there is a way that I can send ble messages from an ESP32 device (I have written a custom door sensor using Arduino) and have hass.io use these messages to display the state of the sensor?
To me it seems easier in terms of battery consumption on the ESP32 to only have to enable ble and send a message then to start wifi, join a wifi network and then submit a mqtt message but i may be wrong?
Most ble add ons I have researched look like they are used for presence detection, does anyone know the best way to achieve what i want above?
Many thanks,
Mike
