Hey All, I've made a pull request for the ZWO EFW to Rumen's fork at github.com/rumengb/indi/pull/1 which makes the EFW work fine for me.
Adding support for multiple EFW is still a TODO.
There's error handling in there, but that can probably be improved.
Here's how it looks when in use :

Hello,
I have some problems whith my ZWO EFWmini.
I have installed the last updated realese (1.3) and my ZWO EFWmini is not recognized.
I have tested on both RPI3 whith Mate and a computer with Kubuntu.
Here is the message when i start indi
*****
2016-11-15T20:39:59 Unable to establish:
+ ASI Wheel
Please ensure the device is connected and powered on.
*****
The EFW is connected and works fine on windows.

If some one have an idea of what goes wrong on my system...
Thanks

Dear Antares,
Can you give more detailed description?
How do you test it?
How do you start indiserver?
Please provide some logs in order to be able to help!

clear skies!
Rumen

Hello Rumen, thank you for your answer.

I did not practice a lot of tests.
I have pluged my EFW on the RPI3 (that run Ubuntu Mate) and launch Kstars then Ekos and finaly starts INDI in local mode.
For testing I choose the devieces as folow :
Mount : Telescope Simulator
CCD : CCD Simulator
Filter : ASI Wheel

The logs that returns indi is in my previous message.
May be there is a log somhere else but i dont know where. If so, let me know where to look
Sorry not to be more accurate in my explanations and I hope my english is clear enough for you to understand (i m french)

David

Hi David,
I suspect there is something wrong with the udev rules.
Maybe running indiserver as root will shed some light.

Can you try to run indiserver from terminal like that:
$ sudo indiserver -v indi_asi_wheel

Then connect Ekos to localhost port 7624

Can you see the EFW now? Does it work now?

best
Rumen

Hi Rumen, thanks a lot,

Just tested your idea this morning and it works.
Here is what I see in the terminal :
2016-11-16T06:11:22: startup: indiserver -v indi_asi_wheel
2016-11-16T06:11:22: Driver indi_asi_wheel: pid=4706 rfd=3 wfd=6 efd=7
2016-11-16T06:11:22: listening to port 7624 on fd 4
2016-11-16T06:12:12: Client 0: new arrival from 127.0.0.1:48989 - welcome!

Here is the log in Ekos
2016-11-16T07:12:21 EFW filter is online.
2016-11-16T07:12:12 INDI services started. Connection to remote INDI server is successful. Waiting for devices...
2016-11-16T07:12:12 Connecting to remote INDI server at localhost on port 7624 ...

What can I do now to make it works permanently ?

I tested whith my Atik 314L+ plus the EFW : both works fine together:-)

Once more, thanks Rumen

David

Hi David,
I have just made a pull request for Jasem with the new udev rules that fix your problem.
however you can apply them yourself:

as root edit:
/lib/udev/rules.d/99-asi.rules

at the bottom:
replace:
ATTR{product}=="ZWO EFW" ATTR{idVendor}=="03c3" ATTR{idProduct}=="1f01" GROUP="users", MODE="0666"
with:
KERNEL=="hidraw*", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", GROUP="users", MODE="0666"

then reload the rules:
$ sudo udevadm control --reload-rules

this will make it work without root.

Hi,
looks great! Is it possible to use this filter wheel standalone with USB connected to a raspi or PC ? My dealer told me that this filter wheel works only together with an ASI camera ?

Thanks,
Klaus

Hi Klaus, Who is your dealer?
Yes, the EFW works without ASI camera. It works with every camera that can work with 1.25" filters.

Great news! Thanks for the prompt response.

Thanks Rumen for the setup guide, I will test it as soon as possible.
To kkretzsch I equally confirm that you can use the ASI FW with other astronomy caméras.For example, I use it whith a Atik 314L+.
You only need a system to drive the FW...of course, choose INDI
Best regards
David

Hello, everybody, hello Rumen,
Sorry to bother you once more
Tonight a had time to do some more tests whith my EFW.
As you said that rules will be chaged in an update, i did the update of my RPI3. I simply lauche the Software updater of ubuntu mate.

Once done, I test to start indi in local mode and, like before, my EFW is wasn't recognize.

So I decide to makes the chages you talk about : change the botom lines of /lib/udev/rules.d/99-asi.rules
When i open the file, I saw that those lines alrady exists. (the update have been done)

Like before, I can use the EFW by lanching it in "server mode" so it is fine.
But, may be there is only little thing to do to make it work in local mode.

Feel free to ask me for more tests.

Best regards
David
