4. "Node 1 is unknown" requires a restart. 2nd child element never presents

"Node 1 is unknown" requires a restart. 2nd child element never presents

  • Cravecode

    I'm attempting to use the TemperatureAndHumidity example sketch.
    Gateway and Node are running 2.0

    When I start up the node, gateway and HA, I get repeat errors Node 1 is unknown in the HA log. To fix this, I restart the temperature sensor and the first child (child ID 0) presents and displays in HA correctly and continues to update. However, the second child (ID 1) never presents leaving HA to constantly logging:

    WARNING:mysensors.mysensors:Child 1 is unknown
INFO:mysensors.mysensors:Requesting new presentation for node 1

    I also tried using the dev branch of Home Assistant with the same results.

    I should also mention I tried configuring the sensor to only run with one child. That worked regardless of whether I was sending Temperature or Humidity sensor info. It seems like it is an issue with 2 or more child elements.

    Temp sensor log:
    Contains initial startup and the first restart to get it working with HA.

    It seems the gateway/controller doesn't receive the presentation of the second child, child 1. Try add a short wait between presenting child 0 and 1. Try with 50-100ms.

    Is your node sleeping? If so add a short wait, 300 ms, before going back to sleep. Then it will pickup the request for new presentation that the controller sends when it receives a message from an unknown node or child.

    @martinhjelmare Thanks!!
    I added a 500ms delay between each sensor's present call. I also added a 1000ms delay before the sensor sleeps. That seems to have fixed the issue.

    I also confirmed that both delays, between children presentation and before sleep were required.

    @Cravecode

    You should use wait and not delay. Delay will block incoming messages but wait will process messages in the background.

    I'll create a pull request to update the Air Humidity Sensor example (DhtTemperatureAndHumiditySensor.ino) and reference this post.
