Platform ble_monitor does not generate unique IDs

[eduperez]

I have several BLE sensors scattered around the flat. As some of them are too far away from the main HA instance, I have configured a second HA instance, and I am using this component to sync all the info to the main HA instance.

As both instances could receive status updates from any sensor, I defined all the sensors on both instances, using the same names, with the intention of having a single entity per sensor, that can be updated from any HA instance. However, when I restart the remote instance, the main instance complains with these messages, and stops updating the entity:

Platform ble_monitor does not generate unique IDs. ID t_Monitor already exists - ignoring sensor.ble_temperature_monitor
Platform ble_monitor does not generate unique IDs. ID h_Monitor already exists - ignoring sensor.ble_humidity_monitor
Platform ble_monitor does not generate unique IDs. ID batt_Monitor already exists - ignoring sensor.ble_battery_monitor

I guess I can use separate names or a entity prefix, then add some automation to update one entity from the other, or perhaps use a template to grab the info from the last updated entity. But it would be much easier if this component could merge the info from entities with the same name.

Thanks!

In trying to figure out how this actually works, but I'm still not sure. Will have to experiment a bit more. Not sure of the implications when allowing something like this, that's also something that needs to be investigated further.

I have move to a different solution, and this is no longer an issue for me. If I am the only one affected by this, the issue can be closed; I do not want to waste your time.

Many thanks!

@eduperez having the same issue here. Can you share what was your different solution?

I had a main Home Assistant instance on a RPi 3, and a secondary one on a RPi Zero. The Zero is no longer capable to boot recent versions of Home Assistant, so I had to abandon this idea.

I installed a bare Raspbian on the Zero, and a small Python program that listens for BLE messages and sends the info via MQTT to the main instance.

This program is based on https://github.com/JsBergbau/MiTemperature2
