Some might find this cumbersome - but it all works good and no problems for SGP controlling everything. Download time for full image (11.5 MB) is about 8 seconds.
I live in SE Spain. The whole set up evolved over a few years (the actual dome only came earlier this year) - that is why each part still has its own adapter. I found it easier just to add another mains supply rather than adding DC supply for everything. It is perhaps a bit ‘heavy’ on cables but in practice, works well.
