Combining multiple domoticz instances

Im having some range problems with my rfxcom 433mhz transceiver, but due to my smart energy meter i am bound to one location (downstairs) with my pi.

I would like to add a second raspberry pi with domoticz on another location (first floor) which will then be used with the rfxcom. This should solve my range problems.
However i do not want to manage 2 seperated instances, is it possible to use the 2 domoticz instances as 1 instance? Synchronisation of some kind?

I use ser2net with other Pi and rfxcomm. I have two Pi:s and two rfxcomm:s. Two separate buildings with ethernet between. One Domoticz in main building.

Me neither. Monday evening i will test it.

I will look into device sharing too but ser2net seems.more transparant.

It has been running since my post. Only one problem has been - I don't have real ethernet between buildings, so I'm using powerline plugs to transfer net via electric cabling. Yesterday 'net' was down - maybe minus 30 celcius is too much for Raspberry or powerline plug. Heating is in todo list. :)

But other than that zero problems.

Ok sounds good. Even better for me would to share the usb p1 converter over ethernet instead of rfxcom.
Then i would use my main pi on the first floor.
Rfxcom is more critical than power usage metrics.
