MQTT client ID should unique/random #7

Closed giddyhup closed 5 years ago

giddyhup commented 5 years ago

Duplicate MQTT client IDs are against specifications. Each device should have its own unique ID. When multiple Hugos are in use this may cause conflicts. Possible conflicts are mitigated since a Hugo is connected to the broker only for a short while but it would be better if the ID would be randomized (as it is done in other projects) and not hardcoded.

Edit: PS.: ~I would also consider randomizing OTA names.~ In OTA names this seems to already be implemented.

Last three segments (6 characters) of the MAC address will be appended in the device name. I will let you know once the update is ready.
