I was able to set up a LiV unit so that it can also be be used as a Domoticz server, running both livpi (port 5000) and domoticz (port 8080) servers. I configured LiV so that at boot time, LIV also starts domoticz and starts pushing data to LiV Pi dummy devices configured in Domoticz. This is done through a Python process that reads local livpi measurements and uses domoticz JSON APIs to write them into domoticz DB.
If anyone is interested in this, I will create a domoticz github branch after I do some code clean up and more testing.
Here are a few photos showing the integration so far:
