The RFXtrx433XL has an option to connect a cable RJ11 for the Dutch DSMR P1 interfaces.
See chapter 16 in the RFXtrx User Guide.
A very few ready build are available at

confirmed working with Domoticz beta, I'm not sure where to best place instructions, but some settings needed experimenting.
As stated in the RFXtrx user guide chapter 16 the P1 connection needs to be configured with the RFXmngr program for the right Smart Meter connection. After that in the hardware setup you need to select the right DSMR Async Type. In my case DSMR_1 worked but I don't understand the logic on how to select the rights one.

In chapter 16 is the list of DSMR meters with the versions and the corresponding baud rate.
Domoticz - RFXmngr
DSMR1,2 9600,7,E,1
DSMR4,5 115200,8,N,1
I suppose it is correct configured by Domoticz if you select the appropriate DSMR in Domoticz at the RFXtrx433XL configuration.

Hi, Did someone already got the P1 DSMR interface working.
I got the RFXtrx433XL which should have the option to wire it to the P1 port. In the manual there is on page 52 intstructions how to connect the P1 port to the RFXtrx however when I open the version I have the PCB looks completly different. There is also no resisitor 15 which need to be changed to get 115200. I would appreciate some input

I got the P1 Option bord ordered and quickly delivered from RFXcom. Installation was straight forward and with some help from RFXcom got the board fully functioning together with Domoticz beta version. It works great and nice to see actual electricity and gas consumption. The board is an recommendation for all RFXcom owners!.
One tip, if you install the board and read the manual carefull for the correct settings to get it working. I didn't read the manual in detail and missed an little thing, But Bert helped me out to get it corrected and functioning! Thanks for all your help.

The input buffer is too small defined in Domoticz and needs an update.
