Just finished now to import the Pegasus Ultimate PowerBox V2 in Viking and Voyager.
You will found soon on version 1.0.19 of Viking.
Like in attached screenshot using Viking and configuring Observing Conditions in Voyager you will able to get also information about Temperature , humidity and dew point.
I/O boards are managed by Viking and Voyager talk with Viking.
Someone use the Serial transmit block of DragScript to manage the out activation only features of UPBV2 but I suggest to integrate them in Viking. You have a lot of advantages.
I personally use UPBV2 and Motorkit focus kit V2 in Voyager and work perfectly
Great telescope, difficult to use in terms of collimations. You need good quality camera to avoid tilt adjustment nightmare. Switching from QHY to Moravian fix all my tilt problem.
