@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze. Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices. And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant. Regards, Edi

@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.

I think the something about order of initialisation was changed that fixed this problem. Try 1.4.1

any idea how often heartbeat messages would be sent?

@nrf24_is_hard When I sent data between an Aduino and the RPi I discovered that I have to make the the receiving and the sending structs the same size AND the variables be on 4 byte boundaries. Change your char name[15] to char name[16] Another challenge is that the number of bytes of type int are different. If I remember correctly, Arduino Uno is 2 bytes and RPi is 4 bytes. To make matters worse, some compilers make the least significant byte the first byte of a word and others make it the last byte of a word. eg, sending the value 1 would be received as 16777216 (0x00000001 vs 0x01000000) There are a lot more gotcha's OSD

This list seems the most complete list of available Home Automation Software and not only open-source and not only for MySensors. I have some proposals: is it possible to add voting here to see, who has selected what software and see what is the most popular HA platform? OpenRemote seems to be more commercial, than open source. In free version it's so limited, that almost unusable. You can add some more Commercial Software in the list, but not sure how they can support mysensors: --Eve Server http://www.ilevia.com/eve-server/ -- Iridium Server http://www.iridiummobile.net/server/ Regards

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.
