You mean it is supported like the AAG cloud watcher but was just not listed in the device list? Where can I find a description how to set it up.
I can select it in Aux1 but will it work in the scheduler modul as a constraint regarding clouds?

I have a question and wish. Why is the Indiduino weather station not supported as Indi/Ekos weather station? It is integrated with Indi but not listed in the Devices list.

mt replied to the topic 'using indi py or dbus scripting' in the forum. 10 months ago

Sounds good, however my favorite was the alternative park position like it is offered in EQMOD.
Here my logic:
UNPARK, set TELESCOPE_PARK_POSITION (AZ, ALT), set TELESOPE_PARK_OPTION (PARK_CURRENT) assuming that current uses the values from PARK_POSITION, open roof, Set TELESOPE_PARK_OPTION (PARK_DEFAULT)

There is another option in TELESOPE_PARK_OPTION (PARK_WRITE_DATA) and I don't know how those function relate to each other.

I am living in Germany near Bremen. Yes I thought about it as well to just use the park position pointing to the horizon. But that requires a lot of space in my observatory. But you are right - also from a safety point of view since you do not need to care about "did it really slew" when working remote. Still I would be really interested how to properly use those functions in dbus or indi py. From the available documentation it is very hard to know how to use.
I get the Switch type function to work but have problems with setting numbers.
Telescope_Park / Switch (park, unpark) =works; Telescope_Park_Possition / Number (AZ/ALT or RA/DEC) =no success.

mt replied to the topic 'using indi py or dbus scripting' in the forum. 10 months ago

I am using an eqmod compatible mount (Avalon Linear). I can run the standard demo scripts of indi py and dbus that is slewing to caph (dbus) respective vega (indi py). But slewing to a position with "equatorial_eod_coord" doesn't help me because throughout the year the mount will slew to different positions. Since eqmod provides the function of an alternative park position (see snap) my first idea was to slew the mount from the nominal park (north star heading) just by 90° out of the way of the roof when opening and set this as the alternative park position. But I couldn't get it to work with indi py. The other idea was to use the "HORIZONTAL_COORD" method to slew. My third trial was to use the "TELESCOPE_MOTION_NS", again I couldn't get it to work.
To your 2nd question "what is the exact location you want to slew to" - I have no exact location it just needs to slew from park NS orientation (vertical) by 90° to horizontal EW (see snap).

I have the following problem. In order to open/close my roof I need to slew the telescope out of the way by 90° (too high). I have tried to achieve this by using either indi py or dbus scripting with no success. I can park, unpark by can't get it to move. I guess should be pretty simple for somebody who knows but I have spend now 3 days without success. I have tried to set an alternative park position - doesn't work, I have tried to use the "HORIZONTAL_COORD" with no success.
Can somebody please give me a hand, should be an 15 min exercise for somebody who know how to do.

Can you please tell me where to find the indi py development manual. I didn't find any link in the tutorials. A pdf would be really usefull. I am playing around to move the telescope by 90° using the "HORIZONTAL_COORD" but don't know how to use it. Just modifying the example code using the standard properties sheet seems not to be enough. The examples are nice but if you want to do your own steps I need something more.

I have played a little bit with the Indi-python package and have two questions:

Can I also use it on a Raspi running Raspbian?
How can I display status messages on what the python script is doing into Ekos?

Hi Jasem, if start writing such driver it will take me several weeks until I have the basic knowledge and another several weeks until something is running. I think it would be better at least better for me ;-) if I could get a driver that is already prepared and I just extend it with the RRD extraction that provides the "Alert set to true if cloud_coverage > 80%" or so.

mt replied to the topic 'file based interface for own made weatherstation' in the forum. 12 months ago

Just to promote my idea a little more.
Find attached 2 screenshots of the data I retieve from RRD using rrd graph tool. It shows rain in %, luminace (day/night)% and cloud coverage % over two days. As you can see my rain sensor is not working propperly I need to add a heater to prevent showing e.g. 50% when it is just foggy outside but no rain. The second graph shows Tsky and Tamb.
I think it would be a nice feature for the INDI weatherstation as well to use RRD. Of course you can retrieve the most current sensor data as well just as plain values instead of a graph to feed it into Ekos.
If anybody is interested to build a prototype that provides an integration into INDI / Ekos I can provide a ready to use database with real data stored and a description of the layout (kind of data in what order). Attached you find a script listing for the creation of my rrd database. The sensor data are accessed by name e.g. "Tsky" (range -20 to 80), "clouds" (range 0 to 100) etc. .
RRD is GPL you find it here: oss.oetiker.ch/rrdtool/index.en.html

Wow pretty complex, but thanks anyway. I am a User of INDI/Ekos not a developer although I do some coding myself.

I was thinking about something more simple like a ready to use plug into INDI/EKOS that reads the most recent data from RRD based on a configuration file that is giving the layout of the data elements stored in RRD i.e. % of cloud coverage. RRD provides an API see for example: oss.oetiker.ch/rrdtool/doc/rrdfetch.en.html

I build myself a weatherstation with a similar design than the INDI weatherstation (based on arduino, melix IR sensor BMP 185, etc. ....). The data are transfered to a raspi and the raspi is writing the weatherdata to RDD every 3 minutes. I am extracting the data from RDD to display them in a browser together with RDDgraphs generated every hour. I would like to stay with it and not move to the INDI weatherstation design.
Now the wish.
I would like the feature to retrive the data from RDD or a given fileformat like "json' stored in the filesystem to use it in EKOS scheduler in addition the the available interfaces.

My INDI server is not local but remote on a raspi and EKOS is still runnig, so I expect that something is going wrong with the bash script within EKOS/INDI? However the script works and the roof is closing.

mt created a new topic ' Scheduler shutdown procedure script works but indi server stops' in the forum. 12 months ago

I am using the scheduler shutdown procedure script function to close my observatory roof. For this purpose I have implemented a simple bash script that is calling via ssh another script on raspi. The raspi is closing a contact and by that the garagedoor motor closes the roof. So far so simple.
I am not using the indi library but just 2 scrpits and it works.
What I however observe is that after the shutdown procedure script completes the indi server has stopped (crashed ? don't know yet) leaving the devices connected. Meaning when I restart Indi the device are connected.
Don't know if this is a bug are not expected behavior because shutdown procedure script expects the usage of the indi library.

mt replied to the topic 'Eqmod bluetooth' in the forum. 12 months ago

I have solved the problem it works now. I had trouble with the raspi 3 bluetooth configuration. I have followed the guidelines given by www.datenreise.de/raspberry-pi-3-bluetooth-verbinden/
Usually the dev/rfcomm0 can be defined by editing the /etc/bluetooth/rfcomm.conf but this did not work on my raspi 3, don't know why. To fix it I have create a script that is run at startup of the raspi to define and bind to rfcomm0 by issueing the following command: sudo rfcomm0 bind hci0 mac-address 1

Thanks for your help
