Second inverter isn't being discovered.

During the configuration I used 'AUTO', but only 1 inverter is added.
On the fusionsolar website I can see both inverters.
Should I get an sdongle for each inverter, or wire the inter-inverter connection differently?

Huawei Solar (version 2.1.2)

SDongleA-05        Dongle-TA22B031xxxx      V200R025C00SPC140   (rj-45 to HA server, no internet access)
SUN2000-6KTL-M1       INV-TA22B032xxxx      V100R001C00SPC177   (sdongle plugged into this inverter)
SUN2000-3KTL-L1       INV-TA225003xxxx      V200R001C00SPC157   (connected with other converter )

Manually trying different slave id did the trick.
1 & 16

Not sure why AUTO couldn't do this.
