Nice, looks neat, are you using the ws5100 or the enc28xx?
Are you willing to share the pcb (eagle / fritzing / etc. ) files?

ws5100.
share... a bit of later.
I had to fix some little bugs.

Very cool! Any more detail you can give on this setup?

@OldSurferDude use a host name for the broker in the configure command (--my-controller-url-address=). Add the host name to /etc/hosts on the rpi where the gateway is. Start the MySensors gatway. When you want to switch brokers, modify /etc/hosts again and restart the MySensors gateway.

Perhaps my definition about "controller", is a bit broad here. What could be done, is to have a thin "controller", that receives MQTT from the existing gateway, hands out IDs if they are requested from a new node, and translate the message into homie compliant topics. That is all it has to do, should not care about the rest of the automation at all. Should also be able to translate back from homie compliant to mysensors. This could be written in python, c#, javascript, rust etc. The benefit is that you have (relatively) easy editing of configurations at hands, without re-uploading sketches to your gateways / nodes, if you decide that node X should be named Y instead. And I am in no way trying to treat anyone as a fool!

Sorry. Hek, I using this code. Vera3 find relay and it works, but also appears 3 door sensors instead of 3 temp sensors. I try to use the my arduino board only with sd18b20 sketch and it work's and show temperature. Is it sketch suitale for vera? @Gambituk said: and here is the modified relay/temp sketch // Running DS temperature sensor(s) and relay(s) on one mysensor arduino node // Combines Onewire and Relay code // 2014-10-14 Pego: Tested and Running on Uno/Clone and MQTT gateway // Example sketch showing how to send in OneWire temperature readings // Example sketch showing how to control physical relays. // This example will remember relay state even after power failure. #include <MySensor.h> #include <SPI.h> #include <DallasTemperature.h> #include <OneWire.h>presen #define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected #define MAX_ATTACHED_DS18B20 16 #define RELAY_1 4 // Arduino Digital I/O pin number for first relay (second on pin+1 etc) #define NUMBER_OF_RELAYS 2 // Total number of attached relays #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) 30000 orig OneWire oneWire(ONE_WIRE_BUS); DallasTemperature sensors(&oneWire); MySensor gw; float lastTemperature[MAX_ATTACHED_DS18B20]; int numSensors=0; boolean receivedConfig = false; boolean metric = true; // Initialize temperature message MyMessage msg(0,V_TEMP); void setup() { // Startup OneWire sensors.begin(); // Startup and initialize MySensors library. Set callback for incoming messages. //gw.begin(); gw.begin(incomingMessage, AUTO, true); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Temp and Relays", "1.0"); // Fetch the number of attached temperature sensors numSensors = sensors.getDeviceCount(); // Present all sensors to controller for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) { gw.present(i, V_TEMP); } // Fetch relay status for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Register all sensors to gw (they will be created as child devices) gw.present(sensor, S_LIGHT); // Then set relay pins in output mode pinMode(pin, OUTPUT); // Set relay to last known state (using eeprom storage) digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF); } } void loop() { // Process incoming messages (like config from server) gw.process(); // Fetch temperatures from Dallas sensors sensors.requestTemperatures(); // Read temperatures and send them to controller for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) { // Fetch and round temperature to one decimal float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.; // Only send data if temperature has changed more then 1 degC and no error if (int(lastTemperature[i]) != int(temperature) && temperature != -127.00) { //added integer // Send in the new temperature gw.send(msg.setSensor(i).set(temperature,1)); lastTemperature[i]=temperature; } } //gw.sleep(SLEEP_TIME); //no sleep for relays!!!! } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller.

After more investigations I believe the problem is caused by a mqtt server connection timeout. By default the gateway tries to send the radio message 5 times. If I lower the number of retries , 2 for example, no more loop. Probably now much more then 25 messages cause a loop. For testing I added _MQTT_client.loop() in transportSendWrite() (MyTransport.cpp) and, no more loop with default 5 retries.

can you login to the mqtt server with any mqtt client for computer (like mqtt spy or similar)?

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@UglyKidJoe I have been using OpenHAB and MQTT for a number of years now. The reason for using MQTT and not just a serial connection from the MySensors GW is partly the flexibility as many have stated previously here. Easy to test, using e.g. the mqtt.fx tool. If you want to know what is going on you simply connect to the MQTT stream and "snoop" on the messages. Another reason is that I am running three geographical sites on one OH installation. OH is running on a NUC at my home. There is also an MQTT GW here. Two other My Sensors MQTT-GW are running remotely in two summer houses. The three GW connect over internet to a cloud-based MQTT broker and OH connects to the same broker. In that way I do not have to open any ports into my home network for access should I have had a local MQTT-broker at home.
