Ihost: cast - device & charts should be usable independently from each other

I am talking about a power consumption switchc like the PowR2 or PowR20D for example, but it can also be usefull for the temperature sensors too.

Currently the CHART is HARD connected to the device. If you “turn of the device” in ihost cast then the corresponding chart will also disappear no matter what.

In my case I want to show the user the power consumption figures of the AC we are using for heating - but for sure I do not want to give them the option to toggle the AC off while running cause that will kill the compressor.

Therefore I should be able to turn off the device in the cast setup without deleting the graph as it happens right now.
