Frustrated Newbie - Help with Nodes and Sensors



  • @jkandasa Okay I have reverted to Com 5 for both MySensors Gateway and Com5 for Mycontroller. I restarted the controller and I was able to connect successfully. Phew!

    That's done, you still didn't say if the certificate error has a role to play. I have connected the sprinkler package to an external power and I am running Putty on the side to listen to Com5 No cheese...



  • @emenike Now your sketch configuration and MyController gateway configuration looks similar.
    The only thing, you should not open COM5 in any service(putty, etc.,) when you enabled in MyController.

    Follows these steps,

    • Disable Gateway in MyController
    • Close your putty and other services, which is listening to the serial port
    • Disconnect your hardware(MySensors gateway) from the computer
    • Reconnect your hardware again to the computer
    • make sure your MySensors gateway is available in COM5
    • Enable your gateway in MyController
    • Now you should see the nodes in your MyController, if not try to run discover on MyController's discover page.

    you still didn't say if the certificate error has a role to play

    Certificate error is completely different than this issue. Some tutorial, You may not worry about this.



  • @jkandasa Wow! That really helped, I was able to not only connect to the MyController Gateway, but two Nodes discovered and Nine sensors discovered. Thanks @jkandasa you never know how hard I tried. all along, connecting and disconnecting Arduino and Putty intermittently without knowing that I was disturbing the line. see what it now looks like. 0_1543747146086_Screen Shot 5.png

    So can I continue troubleshooting my problems with this tread or should I create a new one?



  • @emenike For me, it is ok to continue here. Up to your wish.

    I see the name of the sensor shows some debug message, looks like we have some issue with MyController.
    Can you disable debug in MySensors gateway sketch?

    // #define MY_DEBUG
    

    To update gateway sketch, you need to disable gateway in MyController and update your gateway sketch via Arduino IDE. After a successful update, you can enable gateway in MyController.



  • @jkandasa Thanks.
    I disabled the MyController Gateway, then commented out the debug line on the sketch via IDE. and uploaded the sketch the the MySensors gateway @ COM5. Closed the IDE and restarted enabled the MyController Gateway --- but now one node is down while the Gateway connected successfully. 0_1543792504887_Screen Shot 6.png



  • This is what ot looks like now...

  • @emenike Seems all ok in MyController side.
    Can you check your sprinkler node powered up and in RF coverage?

    Hi All,

    Sorry was out for a couple of days...,

    @Emenike
    jkandasa is right, as an addition you can also add the debug stuff to you sketch and hook it up to your laptop to see the debugging stuff from the sensor perspective...

    If the sensor is out of range of you gateway you have some options to fix it:

    1. you can put a repeater node in the middle between the sensor and the gateway to extend the range of your network

    2. check your radio, exchange it for another one to rule out any radio hardware issues. (some of the radios have issues... especially the Nrf24l01 radios with the round black blob instead of a chip... believe me, I have been there and the range was approx 1.5 meters.....)

    3. If you use the Nrf24l01, add the capacitor to the power line of the radio (tought this was a 47uf capacitor), this will also improve communication (make sure you add this on the sensor and the gateway radio!)



  • @tag @jkandasa

    My Sprinkler node is downstairs - just about 7 meters below the spot where the MySensors Gateway + MyController laptop is (with about 2 concrete walls separating them). Does this matter? For the records, I have capacitor on both MySensors Gateway, and the Water Sprinkler node.


  • MOD

    Can be an issue, can you try if you see the node if it is basically next to your gateway?



  • @tag Okay I will move them closer until I conclude with all the bugs, then I will move them apart and see if distance is the issue

    by the way... is This project in this video a MySensors Gateway or something entirely new?


  • MOD

    @emenike

    Okay, great!,
    Had a look at the link you send, it looks like mysensors, but it is something different...



  • @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.


  • MOD

    @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.
