Frustrated Newbie - Help with Nodes and Sensors



  • @Emenike

    This bit is wrong in your gateway sketch.....

    // Define a lower baud rate for Arduinos running on 8 MHz (Arduino Pro Mini 3.3V & SenseBender)
    #if F_CPU == 8000000L
    
    //#define MY_BAUD_RATE 38400
    #define MY_BAUD_RATE 115200
    #endif
    

    The baud rate in the if statement should be 38400 as it says in the line above it.

    It won't matter if you are using a 5V arduino, but if you were to use a 3.3V one this would be a big problem.



  • @skywatch Thanks @skywatch

    Please note that I am using a Nano for my gate way...
    I thought the baud rate should be the same for Arduino and the Putty sniffer, I will revert to "38400"...


  • MOD

    @emenike

    Make sure that the same baudrate is used in the gateway sketch and mycontroller.....



  • @tag
    😭 but that was exactly how it was until you said to change 38400 …. but it connected alright after | changed to 38400 and brought the node next to the laptop.

    That part of the gateway sketch is an 'If' statement. It just tells the compilier that 'if' the board is a 3.3v 8MHz type, then reduce the baud rate to match. 8MHz boards are not reliable at 115200.

    @emenike

    Okay so if I understand correctly, all works if the nodes are basically next to each other... is that correct?



  • @tag Yes! All works well when they are next to each other on the same desk.
    I have reverted the default baud rate and all is well. I have gone ahead to create Triggers and Conditions, Schedules, Actions, etc. But I somehow can not seem to tie all up to do what I want.

    I want to do a whole lot of things, but lets start with the first one. I need to pull in time and date from the controller to my node. How do I do this? Can I have a simple example that shows the steps or syntax and I will try to do other stuff. The Mysensors node uses a project that pulls data from Weather Underground, which I learnt has stopped its free weather information services. I have researched the topic and found a likely alternative in Open Weather Service) . Is anyone using Open Weather? https://openweathermap.org/current)

    1. I need to create Actions (or triggers that target all 8 objects from my node and set them all "on".
    2. I need to create another action trigger that targets all 8 objects and sets them to "off"
    3. I need to create an action trigger cycles through each value on the node and turn them on for a duration I have a variable in the Controller on each value to determine how long each one will run. Its a whole lot, and it appears I may have bitten off more than I can chew.


  • @emenike

    To receive time in your node, you have to call requestTime(); from your node, then you will receive time on the following function(add this in your node code),

    void receiveTime(unsigned long _timestamp){
       // do actions with received time
    }
    

    I need to create Actions (or triggers that target all 8 objects from my node and set them all "on".

    You need to create 8 Operations for each object. Send payload operation with 1(ON), Add all of them in a rule. define your condition in the rule.

    I need to create another action trigger that targets all 8 objects and sets them to "off"

    You need to create 8 Operations for each object. Send payload operation with 0(OFF), Add all of them in a rule. define your condition in the rule.

    I need to create an action trigger cycles through each value on the node and turn them on for a duration I have a variable in the Controller on each value to determine how long each one will run. Its a whole lot, and it appears I may have bitten off more than I can chew.

    Seems this is complex, we may not easy by simple rule definition/timer. A script will be a good solution for this.

  • Thanks @jkandasa you are awesome support. I see the requestTime() function call in the sketch, but where in MyController do I add the node code?

    void receiveTime(unsigned long _timestamp){
       // do actions with received time
    }
    


  • I have created the UID Tags... See below, did I do it right?UID Tags.png

    I then tried to create the JS script as described in your old reference you supplied... but I got an error.

    What are I doing wrong?



  • @Emenike

    I see the requestTime() function call in the sketch, but where in MyController do I add the node code?

    This code needs to be added to your MySensors node sketch, the example in your sprinkler sketch.
    Nothing to do with MyController to receive timestamp.

    Did you modify the script? If yes, can you post your script?

    If not, you have to create all the UID, valve-status is not available in your UID's list also Value 1 is different then value01



  • Hello @jkandasa
    I have been out of town, haven't touched MYC for a while. Just popped intoday and tried my hands on the script. Ran it after creating the Operation and the Timmer to trigger and run it. But it wont tun. I get an error ```

    {
      "errorMessage": "TypeError: Cannot get property \"status\" of null in <eval> at line number 8"
    }
    

    Here is the JS script that I edited for 8 valves

    with(myImports) {

      //Check already running?
      if(LoopThroughValves.status !== 'running'){
    
        //Update as running
        valveStatus.value = "running";
        mcApi.variable().update(valveStatus);
        mcApi.logger().debug("Loop Through Valve Script Triggered...");
