Dmitry,
Thanks for sharing. The Iridium looks very graphical based which is good. It reminds me of a SCADA package which Home Assistant isn’t but there are plenty of Contributors making more graphical/pictorial related UI. The basic User Interface “Lovelace” is a lot simpler but not very graphical or pictorial.
I’ll look into Iridium PRO a bit and comment more.
With Home Assistant expect lots of Python Language. The Graphical stuff will be JAVA but I generally don’t use that side of things.
Regards, Kevin
