In the aquastream XT tabs you can set a sensor which should be transfered via aquabus to the aquaero. The aquaero will show it as sensor no. 6.
Interesting question here:
Can I hookup the Aquastream XT to my Aquaero, through the Aquabus, if I already have two (2) older style Aquastream's connected through the Aquaero-Aquastream ribbon cable bridge?
Also can I hook both the USB cable and Aquabus to the XT? The Aquasuite software appears to allow this but since the help file isn't in English I am not certain of this. What would be the up and down sides to such a connection?
