Multiple instances issue

[lklimt]

Hello
I know that the multiple instance is still only beta, but I want to report to you following issue:

I have in 2 houses 2 Vaillant heating pums system with bit diff setup /first is normal, second cascade/ - both based on control unit Multimatic. In the Multimatic APP I have connected both, I can switch btw. them and its working fine. In your HA integration I instaled the first one /the normal/ and everything looks running OK. When I wanted to install the 2nd, I start to add the next hub -> user+ pwd are the same, diff is the SN. The second hub was created but it mixed partly on unlogical way in the new created devices inside of the new cerated hub the sensors from the first one and the new instalation - f.e. there was created device where both system pressure sensors was added and the area for the device and both sensors was set up to the new one which I created. OK nothing is perfect, I wanted to correct the area in case of the first pressures sensor to the area of first instalation, but after the area changed for both pressure sensors what is again wrong. Looks like, if 2 sensors how ever from diff. areas/instalations are united in one device, you are not any more free to set up for them diff. areas. And I didnt found the way how to take out one or another sensor from the automatical created device. Looks like, that the sensors from both instalation are correct working /values are inline with the real values/ but it is not easy to work with them, if you can´t distinguish by areas - only what you can use to distinguish is the SN in the created sensor name which looks is correct. Somehow I can deal with it, but its partly very complicated as I have now togethe 55 sensors.

Hello,

how did you install the first instance of the integration ? If you have multiple SN, I would recommend to always use the SN (and nt leave it empty).

Can you show me which devices/entities are mixed ?
In HA entities are grouped by device, and a device is defined by the manufacturer and model. So if you use the exact same device type in both house , this is indeed possible they will be linked.
