Loupy .I really hope some other company comes up with a similar device like the ASIAIR, so the people having to deal with all these problems, at least have an option to go to another product, hopfully made by a company that cares about there customers
Have you tried INDIGO?
At the telescope (Server) end, you can use a Linux or Mac laptop (INDIGO is POSIX based).
https://www.indigo-astronomy.org/for-users.html
With a Raspberry Pi 4, there is INDIGO Sky, which is a turn key install -- burn an image to a micro SD card (like ASIAIR), and plug it in a Raspberry Pi 4 and it will install itself.
https://www.indigo-astronomy.org/indigo-sky.html
INDIGO and INDIGO Sky are free and you just have to supply the laptop or the Raspberry Pi 4.
At the Client (desktop computer) end, you can use pretty much anything (even an iPad), since INDIGO Server comes with an HTTP server.
I.e., just point your web browser of the Client to the server if you don't want to run the INDIGO Client on the desktop machine. The HTTP server will let you do a number of things (manually) including downloading images (FITS, TIFF, etc) from the camera (can be many camera that is supported by INDI), and even picking the WiFi channel that may have the least interference (I have not had any problem with INDIGO's WiFi implementation), or controlling your Dome. There is even KStars on the Server (but even better to run KStars on the local INDIGO Client).
All the above mentioned software is free. If you get more advanced, you can run the full blown INDIGO on the desktop. E.g., KStars running on Desktop, etc.
One of the principles (Peter Polakovic, who is an IT profession for day job) runs CloudMakers -- the other principal, Rumen Bogdanovski is an astrophysicist in the daytime; I always think of one as the brains and the other as the brawn of INDIGO; the heavy coding is done by Peter, and the heavy mathematics is done by Rumen, even though they both share both tasks :-).

I had been communicating with Peter for years now, since he is Mac centric. If memory serves, when Apple released the M1 chip, and I ordered one, and then asked Peter, he already has ordered one. Rumen is more in tune with Linux.
The best thing about INDIGO is that the sources are all on GitHub, ready to run inside macOS Xcode. I have for example added a "Cocoa" layer on top of INDIGO so that all the API turns Apple-like -- NSImage instead of BLOBS for sensor data, Cocoa delegations instead of C callbacks, etc.
But if you don't brew your own code, CloudMakers has some turn key programs that runs (for macOS) on top of INDIGO too, so you have a simple single install process on the client, instead of using a Web server. Things like AstroImager, AstroGuider, AstroTelescope (and even AstroDSLR that are tuned for DSLR):

Or, all of them bundled into INDIGO A1 (all-in-one):
https://www.cloudmakers.eu/a1/
Or the INDIGO D1 (all-in-one for DSLR).
They are tightly Apple-centric that you can buy them at the Apple Mac App store (so will work on multiple Macs for one time cost).
So, it is all out there (just not for Windows people; who have to use the web interface), but you probably never heard of them because the YouTube shills are not paid to tout it, so no one mentions it (always follow the money, especially with this hobby, where a bunch of resistors worth 20 cents are sold as a dew heater for over $40).
INDIGO has a bus architecture. So, you can add any number of servers (I have not come across the limit yet :-) and any number of clients. It is not hard (I don't know if it is already there) to control the dithering of two mounts/cameras from one client so that they dither together, for example. For me, I can work on the algorithms side of software without having to deal with device drivers, etc (which are INDI compatible).
