[libots]

Relabels MQTT topics to work in prefix and container name to enable multiple copies of containers with same image and multiple hosts with containers with same image to not overwrite each other. #261 and #264.

Any indication if this will be merged? Multi-host would really improve the functionality of the program.

I'm gonna do some tests on this soon. By merging this we would break currently running instances, since the topic will change. But probably that's the way to go.

Any news on this topic? I kind of hit the same wall…

Would this Pull Request also solve the issue with entity names in Home Assistant discovery?

For example: My container SERVER-MQDOCKERUP The container status sensor is named: sensor.micrib_mqdockerup_container_status The Start and Stop buttons are named: button.server_mqdockerup_start button.server_mqdockerup_stop

I assume you're using the image to build some entities and the container name to build others.

Is there some updates on this? It could fix a lot of problems, maybe also this #572 !
