homeassistant/smartsleep stops even trying after a few iterations

  • I have a small battery powered node I am using with smartsleep. For some reason though, it seems that after either a certain timeframe or certain number of iterations it just stops waking up and sending the pre/post smartsleep messages.


    I reset it and was watching the mqtt topic. You can see it's consistently reporting in roughly every 30 seconds or so. Just as expected. But then it just stops dead. I sent a state change command via home assistant and the state never changed, the node just seems to be stopping dead after X amount of time/iterations. Oddly enough I saw over the last few days, it will eventually wake up. I had it wake up yesterday morning at 1:46am and today at 4:36am. But when I have it configured to wake up every 30 seconds, doing once a day isn't going to work (im going to flood my yard that way) lol

    I am running mqtt esp gateway, all my other nodes and everything are still functional, so i do not believe it to be the gateway or mqtt. I am running 2.3.2 on the gateway and node in question. Using the easypcb/newbie board with a pro mini and all the necessary capacitors.

    Any thoughts or suggestions?

  • @CrankyCoder Can you provide your node sketch and also activate MY_DEBUG to get a log to provide here? This would be helpful for sure.

  • For the debug i would need to pull the node apart and bring inside and hook serial pins up to the computer. I can and will. Just need to wait for my meeting to end so I can leave my desk.

    For the sketch. Here it is.

    Thanks for taking a peek!!

  • @CrankyCoder My comments to your sketch:

    • be aware that the millis() counter also stops while your node sleeps,
    • when the node sleeps then it will not receive messages, may be someone can help out how to handle this (basically I think the node should request the child node state from MQTT after wake up),
    • be aware that presentation() can be called from controller at any time, not only at node startup, so I would move the non presentation code to setup().

    But for your main problem that the node doesn't wake up after some time I have no idea so far. Hopefully the log helps here.

  • Thanks 🙂 Yeah super odd it just kind of stops. I can see the special "smart sleep" messages telling HA to go to sleep and then they just stop. I even took a repeater out of the equation to see if it was the repeater and the other nodes were going directly to the gateway, so now I only have the gateway and no change. Very strange.

  • I was able to get the module inside without powering it off and serial connected. So I was able to get some logging from while it's in it's broken state!!

    Based on the parser. It seems it can't find a parent. I even plugged in my repeater and it's still saying the same thing. Haven't reset it at all yet, but kind of seems like maybe it's a problem with the radio?

  • @CrankyCoder Yes, your node tries to find his parent but gets no response. And additional the sleep and wake up happens at the same time. Interesting state, your node is in.

  • Well. I swapped the radio. No change. Reset the arduino. No change. So may be time to swap the arduino.

  • @CrankyCoder Yes, may be. But also may be the CE connection from Arduino to the radio is broken.

  • @virtualmkr CE is required to switch between send and receive mode of the radio.

  • Small update. I switched to a radio from different batch and seemed like that fixed it. Saw the smart sleep message in mqtt until I went to bed. But around 4:30am it stopped again. Im going to go pull it again and see what it's outputting. I feel like I need to hook up a bluetooth hc-05 or something so i can just connect over bluetooth at this point to get the serial data lol
