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

    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.

                              I have been struggeling with this for some time now. It seems my compiler is not the standard for raspberry pi? (I have a pi 2). I have used the domoticz sdcard as ground for my system and it works (a bit sketchy with random freezes and I cannot access the domotics webserver from chrome) but still. Anyway, I get stuck on making the RF24 package. Any ideas?

                              pi@raspberrypi ~/RF24 $ make all && sudo make install
                              arm-linux-gnueabihf-g++ -fPIC -march=armv7-a -mtune=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -Ofast -Wall -pthread  -c RF24.cpp
                              cc1plus: error: bad value (cortex-a7) for -mtune switch
                              Makefile:40: recipe for target 'RF24.o' failed
                              make: *** [RF24.o] Error 1

                                  Has anyone used the Raspberry GW software in combination with nodes that run the new 2.0.0 MySensors code ?

                                    It's not supported, 2.0.0 nodes require a 2.0.0 GW. And the raspberry pi port is not updated to 2.0.0 (and unfortunately there is currently no one in the core group that uses the rpi gw.. We all use serial / ethernet gw's of some sort)

                                      I was afraid of that. In my enthusiasm I updated to 2.0.0, but now my new nodes play dead.
                                      At least I know why.
                                      Time to make that old ethernet gateway functional again.
                                      Since Breda meetup is this weekend, I will have no more time to figure this out (if I could ever, this is UNIX). Maybe after I can try something.

                                        What would be required to get the RPi gateway up and running? Having single controller/gateway is great.

                                          Is a 2.0.0 based gateway backward compatible with nodes in an older version ?
