Im currently working on an open source time series database for ascom equipment. The idea behind it is to use InlfuxDB and Grafana which is a very powerful yet simple tool for displaying graphs. There will be no user interaction needed to store the data, as soon as you connect your equipment with the ascom driver, data collection is started and will be stored until you choose to remove it from the database.
Right now I have a few python scripts that are running in the background and collects data from Phd2, tempsensor/humidity sensor, mount (alt/az + Ra/Dec). They are still under development so the data from Phd looks a bit messy.
There is multiple uses for a time series database like this. For instance you could monitor all your equipment over time from a single window in a web browser. It is very simple to access old data so that you can compare e.g. guiding RMS between different sessions or look at your guiding performance for the last 6 months.
It is possible to configure any graph you want with any type of data for analyzing problems or getting more knowledge about the conditions needed for a certain target. If you have a weather station you could compare wind speed with guiding performance. Since i have an observatory i usually go to sleep when imaging, this database will allow me to see what happened during the imaging session. In the attached picture you can see that the star mass dropped between 23:55 - 00:15. This is most likely due to some thin clouds rolling in so images from this time span will be a bit more noisy. You can also see a bump in the Alt angle, this is where the automatic meridian flip occured.
This is just a first test, so there is alot of improvements and features to implement. What do you think of this idea, is this something that anyone would be interested in? If so, i will put the source code and some instructions on how to set it up on github.
It would also be very interesting to hear if you have ideas about what this could be used for. What data do you think would be usefull to collect from your ascom equipment or image capture sofware?
