  Well, I'm back again, because it broke again ... and I fixed it somehow again. I was playing around with my sensor to get it up and running the way I want it to and resetted its node id. It couldn't get a new node ID and I was back where I was yesterday. Deleted everything, rebuild the complete flow, restarted everything. Nothing helped. So I added debug messages everywhere and also had a look into the raw Serial protocol here: https://www.mysensors.org/download/serial_api_20 It looks like you don't need the encode and decode, at least for me the encode after myscontroller totally destroyed the payload. Why did it work yesterday? I have no idea. The payload looked fine now without the decode and encode according to the protocol, but it still didn't work. I noticed that the incoming TCP payload always ended with a linefeed "\n", so I added a custom function between the myscontroller and tcp output to also add a linefeed to the outgoing payload and it's working again.

  You're welcome! I've used node red like you are doing for some times and it works well. Since around 1-2 years I'm using home assistant as controller, and node red for the logic in automations. Home assistant makes life much easier, as it for example takes care of filling data into influxdb automatically

  This seems to evaluate to true/undefined every time, effectively resetting the array: var global_individual_data=global.get("global_invidual_data"); if (global_individual_data===undefined) { msg.kein_array_vorhanden="true" global_individual_data=[]; } even though it's later set with global.set("global_individual_data",global_individual_data);

  @SuperNinja I'm afraid I didn't keep it. On the other hand, linking actuators to sensors was (and still is) very straightforward. Most flows dealt with voice recognition, which has become a lot easier to implement nowadays.

  I reply to myself, I succeeded to make it work. The \n was missing in the payload before sending it back to the gateway. This took me months to see this... Works like a charm now, I just need to implement the inclusion feature in NodeRED.

  Seems that the problem was that influxdb always configures the field type the first time a series is accessed. I thought that the value was something like a "variant" and would eat anything I throw at it. So when I altered the data types in the flow, the db refused to save. A drop and re create solved the problem.

  Hi @sotiriszegiannis, welcome to the MySensors community! By gateway, do you mean a MySensors gateway, or something else? I am not familiar with the term ”node red gateway”. There can be multiple MySensors gateways on the same lan. There can be multiple Node Red installations on the same lan.

  @pansen FYI, I just released a small bug fix for the mysensors node-red module.. So now it should show the correct node ID's in the controller view.

  I'm using a mqtt gateway to send data to the nodes. It is possible you will run into the same issues I guess but that should be easy to test. Just send data on a regular basis to the out node and try to receive at the same time. I use the VAR_1 type in the message of I'm sending data from node red to a node

  @wergeld Odd, I went to the raw file, hit select all in Firefox and right click copy, then went to Node Red and did the import from clipboard, no edits. Maybe it's something related to Windows, I did mine through Debian. Still, good to know that some paths need the single/double quotes repaired so thank you.

  @kduino you should go to "Manage palette" and search for mysensors. From there install node-red-contrib-mysensors or you could run npm install node-red-contrib-mysensors

  As an example, of using the mysensors nodes, here is my current "main" flow, converting mysensors serial protocol to / from MQTT.. The goal is to switch domoticz to run with mqtt at some point in time, and then skip the domoticz <-> mqtt transformation steps. Or even skip domoticz completely, as I only use it for some automation scripts in LUA. All graphing etc. is handled by influxdb / grafana instead. But right now I am leaving domoticz untouched to keep the WAF as high as possible [ { "id": "2257718.fdda88e", "type": "subflow", "name": "Energy meter", "info": "Converts input from arduino sketch,

  How to add a serial device to use in node-red

  here is my solution; add a new udev rules file for permissions: sudoedit /etc/udev/rules.d/50-usb-permissions.rules paste the following in our new rules file: (it gives all permission to any USB* and ACM* devices) KERNEL=="ttyUSB[0-9]*",MODE="0666" KERNEL=="ttyACM[0-9]*",MODE="0666" that's it. this will give you all the permissions to all usb devices on every boot. also you can reload udev instead of rebooting. udevadm control --reload-rules *** please note that this gives permissions to all USB* and ACM* devices. if you're concerned about security you can add the following so that only the mentioned device will be accessable: ATTRS{idVendor}=="XXXX", ATTRS{idProduct}=="YYYY" for example, in my case (output from dmesg): [ 2654.037338] usb 1-1: New USB device found, idVendor=1a86, idProduct=7523 [ 2654.037344] usb 1-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [ 2654.037347] usb 1-1: Product: USB2.0-Serial [ 2654.038531] usb 1-1: ch341-uart converter now attached to ttyUSB0 so, for me it's: ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523"

  use the serial port node, it should be in node-red (if the modbus data is coming in on the serial port of course)

  Hello, I know this is an old post. But i am trying the script getting to work in combination with Domoticz. A did a little rebuild to 2.1.0, and i am getting a RGD light which i can switch to dimmable in Domoticz. I can select color and dim the strip but i am struggeling with the Speed (V_VAR2) and Mode (V_VAR1). How can I adress these two in Domoticz so it is picked up by the node? So i want to set the mode and or the speed from Domoticz to. // Enable debug prints to serial monitor #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_NRF24 //#define MY_RADIO_RFM69 #define MY_RF24_PA_LEVEL RF24_PA_MAX // Enabled repeater feature for this node #define MY_REPEATER_FEATURE #define MY_NODE_ID 9 #include <MySensors.h> #include <DHT.h> #include "FastLED.h" FASTLED_USING_NAMESPACE #if defined(FASTLED_VERSION) && (FASTLED_VERSION < 3001000) #warning "Requires FastLED 3.1 or later; check github for latest code." #endif #define DATA_PIN 3 //#define CLK_PIN 4 #define LED_TYPE WS2811 #define COLOR_ORDER GRB #define NUM_LEDS 60 CRGB leds[NUM_LEDS]; uint8_t gHue = 0; unsigned int currentSpeed = 0 ; int brightness = 96; unsigned int requestedMode = 0 ; int messageType = 0 ; int previousMessageType = -1; String hexColor = "000000" ; unsigned long previousTime = 0 ; void setup() { delay(1000); Serial.begin(115200); FastLED.addLeds<LED_TYPE, DATA_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip); FastLED.setBrightness(brightness); FastLED.show(); } void presentation() { sendSketchInfo("FastLED Node", "1.0"); present(0, S_RGB_LIGHT, "Makes strip said color", true); } void loop() { switch (messageType) { //************** CASE 1 ************** case (1): Serial.print("Hex color override: "); Serial.println(hexColor); colorWipe(); messageType = 0 ; break; //************** CASE 2 ************** case (2): if ( (previousTime + (long) currentSpeed ) < millis() ) { if (requestedMode == 2) {rainbow(); FastLED.show(); } if (requestedMode == 3) {rainbowWithGlitter();FastLED.show(); } if (requestedMode == 4) {addGlitter(80);FastLED.show(); } if (requestedMode == 5) {confetti();FastLED.show(); } if (requestedMode == 6) {sinelon();FastLED.show(); } if (requestedMode == 7) {bpm();FastLED.show(); } if (requestedMode == 8) {juggle();FastLED.show(); } previousTime = millis(); } break; //************** CASE 3 ************** case (3): // Adjust timing of case 2 using non-blocking code (no DELAYs) Serial.print("Case 3 received.

  @ric63 welcome to the MySensors community! The power meter pulse sensor example should be a good base for a sketch. For saving to a file you could probably use the gateway log file, or export data from a controller.

  Hi, The code that is here:"https://github.com/tbowmo/node-red-contrib-mysensors" as a problem with latest mysensors with arduino 1.6.13 and NodeRed v0.15.02. These line: pl = msg.nodeId + ";" + msg.childSensorId + ";" + msg.messageType + ";" + msg.ack + ";" + msg.subType + ";" + msg.payload; Should be: pl = msg.nodeId + ";" + msg.childSensorId + ";" + msg.messageType + ";" + msg.ack + ";" + msg.subType + ";" + msg.payload + "\n"; This way the message gets to the node, the first one doesn't get there. Thanks, Rui.

  Yes it can be done. There are some cases described in the forum. You could start with these https://forum.mysensors.org/topic/1965/nodered-injected-between-domoticz-and-mysensors https://forum.mysensors.org/topic/3150/use-node-red-to-allow-multiple-connections-to-ethernet-gateway/ https://forum.mysensors.org/topic/700/node-red-as-controller/

  I think you made one mistake in the flow, you need to remove "To MQTT" in the Topic item and put "To MQTT" in the Name item else all the message go in "To MQTT" topic. I have start to make the same flow and I found this post, thanks for the job.

  So I had a go at using SOCAT and although it's working it doesn't seem to like multiple connections on the TCP port. Although it will accept the connection it seems to output data from Serial>Ethernet is a round robin kind of way. Reason I had two connections to it was to ensure the pipe was always read as the other post it was mentioned if the pipe isn't cleared there would be memory problems and I noticed not all the data was getting to all the TCP connections.. Anyway here is the code if you want to check it out. Socat sudo socat PTY,link=/dev/ttyS81,mode=666,group=dialout,raw TCP-LISTEN:40501,fork,reuseaddr & sudo socat PTY,link=/dev/ttyS82,mode=666,group=dialout,raw TCP-LISTEN:40502,fork,reuseaddr & NodeRead [{"id":"e9998a90.266cc8","type":"serial-port","z":"a89027d9.b1ef08","serialport":"/dev/ttyS82","serialbaud":"9600","databits":"8","parity":"none","stopbits":"1","newline":"\\n","bin":"false","out":"char","addchar":true},{"id":"ee7d4fbe.58c5f","type":"serial-port","z":"a89027d9.b1ef08","serialport":"/dev/ttyS81","serialbaud":"9600","databits":"8","parity":"none","stopbits":"1","newline":"\\n","bin":"false","out":"char","addchar":true},{"id":"50839f8a.fbcaa","type":"debug","z":"a89027d9.b1ef08","name":"Full-Debug","active":true,"console":"false","complete":"true","x":595,"y":575,"wires":[]},{"id":"d5b18044.18e1f","type":"tcp in","z":"a89027d9.b1ef08","name":"MYS-GW-OUT","server":"client","host":"192.168.1.150","port":"5003","datamode":"stream","datatype":"utf8","newline":"\\n","topic":"MYS-GW-Output","base64":false,"x":103,"y":963,"wires":[["db05059b.37e4e8","4f3b7e79.739e6"]]},{"id":"c462686d.bb5a78","type":"catch","z":"a89027d9.b1ef08","name":"","scope":null,"x":387,"y":574,"wires":[["50839f8a.fbcaa"]]},{"id":"9fdda3da.86eb7","type":"debug","z":"a89027d9.b1ef08","name":"PayloadDebug","active":true,"console":"false","complete":"payload","x":584,"y":666,"wires":[]},{"id":"db05059b.37e4e8","type":"serial out","z":"a89027d9.b1ef08","name":"ControllerOne-Out","serial":"ee7d4fbe.58c5f","x":619,"y":875,"wires":[]},{"id":"75f6db75.bba3c4","type":"serial in","z":"a89027d9.b1ef08","name":"ControllerOne-IN","serial":"ee7d4fbe.58c5f","x":103,"y":894,"wires":[["6bbbe087.e897"]]},{"id":"6bbbe087.e897","type":"tcp out","z":"a89027d9.b1ef08","host":"192.168.1.150","port":"5003","beserver":"client","base64":false,"end":false,"name":"MYS-GW-IN","x":605,"y":949,"wires":[]},{"id":"4f3b7e79.739e6","type":"serial out","z":"a89027d9.b1ef08","name":"ControllerTwo-Out","serial":"e9998a90.266cc8","x":625,"y":1044,"wires":[]},{"id":"73b94814.883c88","type":"serial in","z":"a89027d9.b1ef08","name":"ControllerTwo-IN","serial":"e9998a90.266cc8","x":104,"y":1045,"wires":[["6bbbe087.e897"]]},{"id":"8121ed9b.ba597","type":"tcp in","z":"a89027d9.b1ef08","name":"ControllerOne-TCP-Out","server":"client","host":"127.0.0.1","port":"40501","datamode":"stream","datatype":"utf8","newline":"\\n","topic":"","base64":false,"x":151,"y":731,"wires":[["9fdda3da.86eb7"]]}]

  This looks awsome and exactly what i was after. I use ESP8266's with NRF24L01+'s as relay nodes connecting back to a cloud mqtt server but have had to statically assign id's. Thanks!!!

  Ah cool So yes, make the user do it. I like the sound of that. Time stinks. Only thing I can say about that is, "Never again."

  Not yet, but that was my goal tomorrow. My GH account is https://github.com/jwcrawley It'll be obvious when I add in the repo I'll also mention it here. Sincerely, Cranky

  @tbowmo May you please share your node-red set up by exporting your setup as flow? If feasible for you
