    I have been thinking about giving this a try But:-
    The Raspberry port is using protocol version 1.4.
    Do the sensors also have to use version 1.4?

    No, the sensors can be running 1.5 or 2.0-beta, the PI will run a 1.4 version.
    The only thing not supported by the PiGateway is message signing.
    But I have a mix of sensors in 1.5, 1.6-beta and 2.0-beta in my home network, so it certainly works.

      @GertSanders

      Is it best to start with a blank jessie image and manually install/compile domoticz or just use the domoticz sd image?
      The latter would be the easiest for me because i am useless with the CLI but if the first method is best??

        Adding support for signing on a pi gw should just be a matter of implementing random number generation and use software signing. With slight modification in the software signing backend as it assumes Arduino api:s for obtaining a seed for the rng.

        Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

          @rmtucker if you want to be able to run the very latest version of Domoticz, use the Debian image and compile Domoticz from git.

          I use the Domoticz image. The downside is that I need to wait for new "official" Domoticz builds before upgrading, but the upside is that getting up and running was very easy.

            Actually ... I started with an official Domoticz build, and then I indicated in the settings that I wanted to update with the beta version. Since then I'm always on the latest beta (v5143 at the moment).

              @GertSanders cool. How often is the beta updated? Every build?

                Just set this up on my existing Raspberry pi B+ Domoticz server and it is working perfectly so i have managed to get rid of the uno Gateway.
                Thank you so much,I can now try and squeeze it all in the Raspi case and the job is finished.

                  This is the cpu usage,the spike is me compiling the software as above.

                    Well, that seems to be the case. Sometimes I see daily updates, sometimes a week passes by without any changes. I selected the BETA channel for updates and since then I have seen new functionality come in on a regular basis. Not all of it is relevant to Mysensors of course, but none the less it's fun to see Domoticz is developed actively.

                      @GertSanders I have seen no issues in Domoticz stable with CPU usage. Thing just purrs along. Will have to check when I get home but i believe my system uptime is approaching 1 year. It "just works" as they say.

                      I would like to upgrade to mysensors 2.0 library by it looks like the Pi repo has not being updated as often (last I checked, anyway).

                        Correct, the PI repo is basically unchanged. But it still is compatible with the 2.0-beta Mysensors library.

                          @GertSanders What? I was under the impression that some features (like sending messages to nodes from domitcz wouldn't work).

                            Did not notice that, I can send values and "switch on" messages to nodes. The only thing I miss is the signing via ATSHA204. Even V_TEXT sending to and from nodes works.

                              I have some trouble with the gateway not storing the network map, if i restart the gateway my non-sensor nodes need to send some kind of heartbeat to reconnect to the gateway.

                              Is this a known problem or is it something wrong with my setup?

                                Yes, known problem.

                                I had some hopes on @marceloaqno and @aaron832 providing a PR into development branch (so we can scrap the old RPI code). But there hasn't been any activity in a while.

                                  @hek But insted of including heartbeats from every non sensor node (trying to keep 2.4 ghz traffic to a minimum), can i solve this by using an arduino repeater node? So the repeater knows the network map and sends heartbeat to the gateway.

                                    No, not possible. The repeater won't propagate it's knowledge about all sub-nodes.

                                       It handles radio network routing, relaying and ids.
