Only one device is discovered by HA

[Blueforcer]

I have two identical devices and each get a own id with device.setUniqueId(mac, sizeof(mac));

unfortunally only one device is registered in HA at a time. I need to delete the first one in in order register the second device.

in HA logs i found this when i try to register the second one:

2023-03-27 23:19:10.475 ERROR (MainThread) [homeassistant.components.sensor] Platform mqtt does not generate unique IDs. ID battery already exists - ignoring sensor.battery

2023-03-27 23:19:10.482 ERROR (MainThread) [homeassistant.components.sensor] Platform mqtt does not generate unique IDs. ID illuminance already exists - ignoring sensor.illuminance

what is wrong here?

Check out issue #124 and #149

Each device must have a unique id and each sensor name must be globally unique, regardless of the device name they are associated with.
