RFY (somfy) relay device -> on/off inverted

Hello,
I use domoticz with a Raspberry pi + RFXCom E version.
When using this kind of device :

A somfy rts (RFY protocol). On status is "off" and off status is "on".
How can I solve this issue ?
Thanks.

Hello,
I do confirm. Somfy power switches are correctly managed with rfxmngr application ( UP cmd = Switch Power ON & DOWN cmd = Switch Power OFF) but with domoticz on Raspberry pi + RFXCom E version commands are inverted
How can this be fixed?

Same here, testing the RFXcom in combination with the Somfy Powerplug (e200 RTS). Everything works correctly with the rfxmngr application, in Domoticz it's inverted, when i turn it off in the aplication, it goes on and vice versa. Hoping for a solution.... Testing now on Windows 7, i want to finally install it on a synology NAS.

Same problem with the Somfy Lighting Modulis RTS Receiver Dimmer (pn: 9014281), also inverted, so can't dim in Domoticz. I can only turn it off (=on) and on (=off).

i've made the next workaround to make the powerplugs work for me:
-created a dummy switch ("Tuin Waterval").
-created a real switch ("Somfy2"), the actual powerplug.
-created the next blocky:

When I turn the dummy switch "on" then "Tuin Waterval" is "on" (but the real powerplug is in domoticz "off").

today my somfy devices didn't turn on, after i had updated domiticz. Thx to above post i understand why. So, i've removed my virtual switches for the inverted somfys
