smart sleep inconsistent?



  • I have a node I setup and configured for smart sleep. It's set to check in every 30 seconds. But it's not consistent. I understand without a real time clock ect that it may not be 100% on the wake up procedure... but i am getting BIG gaps of time where it just isn't reporting in. The below graph is monitoring my mqtt broker and you can see big gaps and that is just over the last hour. 1 gap was for 12 minutes then ok for a bit, then a gap for 15. I monitored during my last meeting so i could confirm it wasn't me messing with something.

    This has been going on for a couple weeks. The only thing I can think of is maybe it's doing the FPAR like I saw awhile back. I have changed out the arduino, changed the radio, changed to another radio from a different batch.

    Not sure if anyone has any experience with the smart sleep, but so far it doesn't seem super reliable. Not enough so for me to be willing to have it not turn off my water for a couple hours till it decides to wake up after flooding my neighbors drive way.... not speaking from experience or anything lol



  • additional information:

    • wemos d1 mini mqtt gateway
    • tried with and without repeater
    • tried moving gateway closer to node (easier than moving node)

  • Mod

    @CrankyCoder can you share the node sketch?

    You don’t happen to have gateway and/or node debug logs?


  • Mod

    Oh, and what hardware is your node? Atmega328?



  • @mfalkvidd sketch is here. I don't have the debug logs off the gateway, but ill hook up serial to it this weekend and get some logs. (i need to just make one of those bluetooth to ftdi adapters lol)

    hardware is 3.3v arduino pro mini for the node and wemos d1 mini for the gateway.

    @CrankyCoder if I understand correctly, the mqtt plot you provided is how often the battery status is sent?

    And your expectation is that the battery status would be sent approximately every 30,000 milliseconds?

    If so, the problem is that millis() is frozen during sleep. So the logic in the sketch is wrong. The sensor will report battery status after being awake 30000 milliseconds.

    You can verify this by printing or reporting the value of millis() on the node.



  • The 30 seconds is what is passed to the smart sleep function based on the smartsleep() documentation. In this case SLEEP_TIME = 30000. The other stuff in the code around the millis() check i understand would be halted, but I believe the smart_sleep is different based on the documentation.

      #ifdef MY_DEBUG
        Serial.println("Going to sleep");
      #endif
      smartSleep(SLEEP_TIME);
      
      #ifdef MY_DEBUG
        Serial.println("Awake Now");
      #endif
    


  • Another quick update. I hooked my gateway up to my computer to get some debug logs off it. I am not seeing ANYTHING coming from that node using smartsleep at all. So it does appear the issue is specifically with that node.

    Since it's battery powered i am going to see if i can get serial connected up without a reset and see what's it saying but i have a feeling it's going to be what ive seen before and it's having a hard time finding a parent for some reason. Not sure how to fix that.



  • @CrankyCoder I have similar issue with a couple of nodes. Sometimes it looses signal for hours at a time...

    It might be external interference from other devices like wifi, bluetooth or microwave oven.

    It can also be connection issues especially with the push-on dupont connectors as when the temperature/humidity/air pressure change then the connectors can move slightly. Also they might be badly crimped in the first place.

    So check all connections are good and can't move (soldering is best here), and then look for sources that might be an issue.

    It could also be another node closer to the GW is sending at the exact same time as the problem node and masking the signal.

    Batteries are susceptable to variations due to temperature too, they are a chemical reaction. So try a better source of power for testing too.

    Looking at the code, send_status_message only ever sends 1 - is this what you want? It seems to never send anything else (like 0)....

    Also you are using sleep but have a receive function - what happens to messages when the node is asleep?

    You are sending battery level every second? That is too often. How long will the batteries last? This wastes battery power a lot. I check betteries once a day on my security sensors, they don't change for weeks at a time....

    Have you modified the pro mini as per the battery page on this site? Have you added capacitors to the radio module?

    directionControl seems like it will always turn off both digital pins regardless of the message as //disable are the last statements to be actioned?

    You can try changing

    #define MY_RADIO_RF24

    to.....

    #define MY_RADIO_RF24
    #define MY_RF24_PA_LEVEL RF24_PA_HIGH

    options for power are MIN, LOW, HIGH, MAX. - it might help.

    battery is only sent when there is a change in the voltage.

    @skywatch said in smart sleep inconsistent?:

    Looking at the code, send_status_message only ever sends 1 - is this what you want? It seems to never send anything else (like 0)....

    Where do you see that? i get 1 and 0 reported as needed based on the state.

    @skywatch said in smart sleep inconsistent?:

    Also you are using sleep but have a receive function - what happens to messages when the node is asleep?

    That is what smartsleep does. It tells my controller (homeassistant) to queue up the messages. Which works fine, as long as the node wakes up.

    @skywatch said in smart sleep inconsistent?:

    Have you modified the pro mini as per the battery page on this site? Have you added capacitors to the radio module?

    Correct, modified for battery use, and capacitors to the radio module.

    @skywatch said in smart sleep inconsistent?:

    directionControl seems like it will always turn off both digital pins regardless of the message as //disable are the last statements to be actioned?

    This is correct, this is a directional H-bridge controller to pulse a latching solenoid valve, so I do not need them on but very briefly.



  • @skywatch said in smart sleep inconsistent?:

    #define MY_RF24_PA_LEVEL RF24_PA_HIGH

    I have the node and gateway on my desk now for testing, so I am going to reflash with this now! Fingers crossed it helps. 🙂

    Running it through the log parser it would appear the gateway is responding to the find parent request.

    BUT. The node it self seems to be failing to find parent periodically. Like it's not getting the message back from the gateway.

  • Mod

    !TSM:INIT:TSP FAIL indicates that the radio chip is not responding to the arduino's commands.

    The most common cause is unreliable wiring. But it could be something else. Define MY_DEBUG_VERBOSE_RF24 to get more details.


  • Mod

    Btw, are you using MySensors 2.3 on the node and the gateway?



  • @CrankyCoder Do the data drop outs have any correlation to the solenoid valve operating and does the valave use the same power supply as the node MCU?



  • @mfalkvidd Will add this now.



  • @mfalkvidd said in smart sleep inconsistent?:

    Btw, are you using MySensors 2.3 on the node and the gateway?

    Correct 2.3 on node and gateway.



  • @skywatch unfortunately no. This is for a sprinkler valve that I haven't set up any automations for yet since the questionable reliability at the moment would flood my yard lol



  • Not sure if this helps or if anything jumps out, but here is the node and gateway side by side. Node does find parent request, gateway sees it, responds with 0. But node never gets it.

  • Mod

    @CrankyCoder I am not sure but to me it looks like it takes a bit more than 1 second for the gateway to send the response? And by then, the node has already gone to sleep so it can't receive the message.



  • @CrankyCoder How far apart are the node and gateway? What is between them? Can you post any photos of of each with the wiring?
