Thanks for the update, now I could register and connect for the very first time to my Stellarmate from my ipad Pro. The Stellarmate app is still the version from a week ago, so the connection troubles were not caused by the app as I see.
I could create a new profile for a ZWO ASI183MC camera. I didn't connect the cooling, it looks like I cannot make an exposure without having the peltier on. When I tap on "Loop" in Ekos it says on the top of the screen "Setting temperature" and I cannot take an image. Is there an option somewhere to capture images without cooling on ?
