Anyone Using Rpi as MQTT gateway ?

mainali 11 Feb 2015, 15:05 last edited by

Hi

Is there anyone using MQTT as gateway for connecting to openHab running on another Rpi. If so please help with any links, post or any information to direct me on the right path.

@mfalkvidd thank you very much for your quick answer! I'll look into that.

@Chester good point, but I was restarting the arduino and still couldn't get this to work correctly. Also, the missing "end" was just missed out of the paste here, it was in my code.

As promised, what I found so far: the following dockerfile yeilds a usable cross-compile environment, provided you use it with a Makefile. FROM ubuntu:xenial RUN apt-get update \ && apt-get install --yes \ vim \ build-essential \ git RUN git clone https://github.com/raspberrypi/tools RUN git clone https://gist.github.com/3873805.git /build WORKDIR "/build" CMD ["/usr/bin/make", "CC=/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-gcc" , "HelloWorld"] # Seems I need a real makefile for the above to work. For cross compiling mysensors to work, hoever, you also need to properly seed the variable in configure, for it to work correctly. This is where I left off.

slight bump to this topic rather than starting a new one since I have some more questions Are there any example sketches for setting variables on a node? Thinking I'd want at least 2 variables. Is there a proper way for a node to report time to the controller or other nodes? This one will be powered 100% of the time so responding to messages shouldn't be a problem. I'm pretty sure I know the answer to this one but best way to set up a sketch to report the temp every X when it isn't the main function of the node. Thanks in advance.

@A3V such a feature would definitely make sense now that gateways can have local sensors. But no-one has added it unfortunately. A solution could be to use the code at https://github.com/mysensors/MySensors/blob/2e00bf6a10f76d6aaa1999e12313237bc3edabd3/core/MyTransport.cpp#L446 as inspiration and do something similar at https://github.com/mysensors/MySensors/blob/2e00bf6a10f76d6aaa1999e12313237bc3edabd3/core/MyGatewayTransportEthernet.cpp#L175

@5546dug Yes I think you need 1.4.1 or latest. The messages you see (0;0;3;9...) are traffic in the wireless sensor network. My problem appeared again. The EthernetGateway responds to Ping but Vera plugin says: "Cannot send command - communications error" So perhaps increasing power could help, but how? Is adding capacitors enough?? Like for the radio there already is one..
