Dear @ll,

i'm a complete newbie and am trying to build a proof of concept.

My idea is having a fitbit device or other bluetooth wrist device

node for reading :  
.. HR - BPM,  
-- SPO2  
-- body temperature,  
-- ECG  
and publishing to a MQTT broker

node for reading:  
-- ble i2scan node for detecting presence  
and publishing to a MQTT broker

node for reading an android device (mobile) sensors publishing to a MQTT broker.

presenting these data with dashboard.

some flows for alert - signal / telegram / whatsapp

For that, i kindly ask if someone can help me as a mentor or guidances to accomplish my initial projetc.
