I started trying INDI about a year ago as I was transitioning from unguided to guided exposures. I recently finished putting together the setup shown in these pictures.
I use Astroberry on a Raspberry Pi 4 to control everything remotely. There is a single cable going to the mount from the rest of the world: a 12V power cable, coming from a 12.5A source.
I wanted to have the least number of cables running across moving parts: the raspberry sits on the main telescope and so it moves with it, together with the cameras and electric filter wheel (and I hope an electric focuser in the future) that are connected to it (well, EFW is in fact connected to the ASI1600MM hub, the ASI120MM not, as I felt it worked better plugged in its own port at the raspberry). The raspberry connects to the mount via Bluetooth.
There is a power box (described in a previous post ) attached to the RA arm of the mount. It sources power to the mount and the camera cooler (12V) and to the Raspberry Pi (5V). Power cables to the raspberry and camera cooler run through the declination arm.

[quite="rickbassham" post=58200]You've inspired me to create this:
It doesn't control the session, but will let you keep tabs on it from a mobile device.[/quote]
Looks like a great starting point. I'll check it.
Sorry for my ignorance. I see now that Ekos uses Dbus for scripting. I should have done my homework before posting...
Thank you for your replies. I wasn't aware of Ekos live. Not exactly what I was looking for, but close.

Just to give proper closure to the thread I started... Here are some pictures of my current setup, including the box I put together to distribute power to the mount and camera cooler and supply 5v to the Raspberry Pi from a common 12v input.
As I commented earlier, I'm now using a Meanwell 12V 12.5A power supply. I fitted it with a long cable ending in a 5.5 x 2.1mm plug. I know there are better connectors, but in this way I can still use it directly into the mount if necessary (without modifying the mount). I also feel I rather see the cable disconnect itself if accidentally pulled.
The box is thus fitted with a female 5.5 x 2.1 mm plug input. It could be alternatively sourced from a 12v battery. Here some views of the inside:

With this particular mount the power connector is unfortunately flimsy and causes voltage drops and communication issues. I replaced the connector with a screw secured one and didn't have these issues after that.
