Yes. Using kstars as a normal user, remotely connecting to a manually created indi server as prescribed OR using the indi web server(!), the EFW appears in my INDI control panel and I was able to connect to the filter wheel. I probably will not get to connect it up the full telescope setup until this weekend.
I'm now trying to sort out a remote connection where my laptop connects to the RPi as that was my original intention 6 months ago. It's also where my RPi/Linux knowledge fades. I'm getting connection issues (e.g. too slow / timeout) when pointing at the IP:port. I'm sure I can find a thread on those issues, though.
1. The EFW will not work under a local connection (June 20, 2017)
2. Make sure indiserver is properly configured to allow a remote connection (I didn't have indi_asi_wheel in my indiserver, which is why it did not connect - the web server made the apparent!)
But I think the original purpose of the thread has been solved. Thanks, Maudy!!! Please let me know if you hear anything from ZWO.
C11 on CGEM, ATIK314L+, ASI120MM on ST80 for guiding, motorized Moonlite focuser, ZWO EFW with Ha, OIII, and SII and Lum, all connected to RPi 3 with Kstars/Ekos/Indi
After a quick change of the systemd service file back to a user and not root. The ASI224 did connect and a test image was taken. This was done both with the local indi server and the INDI web manager running as a USER - Yay!
With the initial success, I will test a complete setup: RPI3 -> ASI1600 -> ASI EFW + ASI224 (another config is to the ASI174), and then a future setup of RPI3 -> ASI1600 -> USB2 hub -> ASI174 and Focuser.
