Actually, I've just discovered the Auto-debayer flag under Camera&FilterWheel>Options>FITS>Auto-debayer.



I have this same problem with the DSI III pro (ie monochrome) on Kubuntu 20.04. Will this same fix work for that too, and how should I install it?

Hi Stefan,

Sorry for the delay, my computer broke and I had to buy a new monitor.

I'm sure you saw this:

def strISState(s):
    if (s == PyIndi.ISS_OFF):
        return "Off"
        return "On"
def strIPState(s):
    if (s == PyIndi.IPS_IDLE):
        return "Idle"
    elif (s == PyIndi.IPS_OK):
        return "Ok"
    elif (s == PyIndi.IPS_BUSY):
        return "Busy"

                print("B       ""("+t.label+")= <blob "+str(t.size)+" bytes>")
# Disconnect from the indiserver

This is what I use and it works fine.

What difference does it make? I imagine they both work. The first one is more Pythonic and in the longer term you will find it easier to maintain.

If you write procedural code, like your second example eventually it will become more spaghetti-like and you split it into classes to maintain it. Much easier to start with classes.

Sorry to lecture you.




Finally, the following command had no effect:

indi_setprop "SynScan.EQUATORIAL_EOD_COORD.RA;DEC=10;80"


Hi People,

I've just done a new INDI install on a newly installed RPi3b+ with up-to-date Raspbian connected to a SynScan mount via the handset cable. I also upgraded the Handset to 39.xx. I then installed PyIndi-Client and wrote a quick microservice to call from my custom app.

Broadly things work. As I have said many times, INDI is a tremendous labour of love and I want to make it work. Here is a list of my tests:

1) Indi connection:
- the little server app works and starts the correct profile with SynScan and CCD simulator.
- It can be remotely managed from a webpage on my PC with
- Ekos on my PC connects to it and shows the right devices.
- PyIndi connects and shows the right devices.
- If I disconnect and reconnect in Ekos, it says /dev/ttyUSB1 already in use by another process and I have to reboot the RPi.
2) SynScan tests.
- SynScan connection works. When SynScan powered down, INDI times out and reconnects when powered up.
- GEOGRAPHIC coordinates broadly work, although at some stage the altitude switches from 88m to 127m

       LAT(Lat (dd:mm:ss))= 50.8672
       LONG(Lon (dd:mm:ss))= 359.663
       ELEV(Elevation (m))= 127.1

I haven't chased this down any further. The error shows on Ekos and the handset.
- Set time works, get time does not. The clock on Indi does not update, although the handset is correct. Ekos and the control panel show the wrong time always, apart from the second the time is set.
- Tracking broadly works. There are some random issues, for instance I have encountered situations where the mount is tracking, but the displays (on the handset, on ekos and in PyIndi-Client are all updating wrongly. I can't repeat this, sometimes it does it, sometimes not. It doen't cause a problem because of the next issue.
- Sync almost never works, and this is my main problem. It almost never works with Ekos, it never works with PyIndi-Client.
- Move NS or EW works everywhere. Change slew rate works everywhere.

So, in summary, if I can't sync, I can't share coords with PHD2, and that is my main requirement. It means I have to manually enter the DEC in PHD2 and use the ST4 port on the camera for guiding.

But apart from that, it works, and it's usable and it's neater than the solution I had before.

If I can help, please shout.

I have old cameras that connect to Linux, like the Canon 350d (older than the 400D) and also a NIkon D5000. I'm sure it's something simple like:

- dodgy cable,
- flat battery,
- etc.

The PMP setting shouldn't make any difference. Maybe it could get locked if you have automount on, but lsusb should still work.

Does it work at all, even without a USB cable?

try dmesg and see if there are any helpful messages.





Hi Guys,

Well this is a very one-side conversation. Here is my update so far. I have rebuilt my RPi3b+ several times with:

Ubuntu-Mate 20.04 64bit: very slow, almost unusable.
Ubuntu-Mate 20.04 32bit: still very slow, didn't continue.
I didn't try the 18.04, maybe that would have been OK.
Raspbian (most recent release mid-2020): Seemed fastere.

installed rlancaste github installation for Rpi3. Very slow and hung several times. Changed compiler flags from -j (.... -2) to -j(....-1) and then -j(.... -0). The compile finally completed with one error on weather.cpp. I didn't worry so much.

The issue with -j (which is the number of processors to use) was caused by memory utilisation. Even running at 25% CPU utilisation, memory utilisation was 70% at times. Obviously more processors pushed it even higher.

KStars, PHP and Indi seemed to install OK and I can detect hardware and loop photos, which I couldn't before. The RPi3b, seems a little under-powered, but the big lesson was I needed to upgrade Raspbian before I could install KStars/Indi etc. I should probably also buy an RPi 4. But the RPi 3b+ is still good enough. A 240 sec exposure will always take 240 secs, and a faster processor won't change that.

Good luck to anyone reading,
