Don't see my Arduino node device in Vera

  • I'm new to MySensors and Vera. I have a GoControl Z-Wave thermostat installed and working in Vera, so I know that Vera is working to that extent. I built a serial gateway using the GatewaySerialNano code and a genuine Arduino Nano board. I configured the gateway in Vera and I see "MySensors Plugin" in the "unknown category" devices. I then built a temp and humidity node using an Arduino Pro and a BME280 sensor. I don't see anything in Vera that indicates the BME280 is present. Here's the node code:

    // WNG mods
    // 8/08/17 - Used MySensors example plus Sparkfun BME280 example to make a sketch
    //   that uses BME280 sensor. Not tested yet.
    // Sparkfun example here:
    // Original MySensors sketch here:  
     * The MySensors Arduino library handles the wireless radio link and protocol
     * between your home built sensors/actuators and HA controller of choice.
     * The sensors forms a self healing radio network with optional repeaters. Each
     * repeater and gateway builds a routing tables in EEPROM which keeps track of the
     * network topology allowing messages to be routed to nodes.

    This looks normal to me, yes?

    My question: Why don't I see the node in Vera? There must be something I haven't set up.

  • Another question: Is there a way to see debug output from the serial gateway? Since its USB port is connected to Vera, I don't see a way to get debug info from it.

  • Mod

    If you have an esp8266 around you could make an ethernet gateway making it easier to debug

  • If you go to Apps>Develop apps>Serial Port configuration, do you have the settings there set correctly? This is what mine looks like:
    Your name and device number may be different depending on your serial adapter that you are using. The other settings should be the same though. Baud should be 115200, Parity should be none, data bits should be 8 and stop bits should be 1. Then select your MySensors Plugin that you created under "Used by device". If these settings are not correct, the gateway will not work.

  • @billgoolsby said in Don't see my Arduino node device in Vera:

    MySensors Plugin

    Did you go into the MySensors Plugin setting and include the new sensor?

  • @gohan, I do have a W5100 I could try, but I thought of a way to see the serial stream between the gateway and Vera: put a TTL-to-USB serial adapter on either the TX or RX lines from the Nano. I'll try that first.

  • @dbemowsk, This is my configuration:
    0_1510018152280_screen shot of serial port setup.JPG

  • @r-nox, No, didn't do that - where do I go in the Vera menus to do it? I don't see anything that looks likely.

  • @billgoolsby Go to Devices in the menu and click on the MySensors Plugin device. Next, click on Settings. You should now see something like this:
    Click on the start button and then reset your node that you built. The node should go through it's initialization process and present itself to the controller. Below the start / stop buttons you will see "0 devices found" at first, and then once the plugin sees the node, you will see that number change. If you have a node with one sensor, you should see 2 devices found. One is the sensor, and the other is an object for the node itself.

    Once this process is complete, you can back out to the devices menu. Under "No Room" you should see something like this if your node is a temperature sensor for example:
    Of your node has more than one sensor, then you will see an object for the "Arduino Node X" and an object for each sensor on that node.

    Once the inclusion process is complete, you won't have to add the node again. You can then go into each object and set it's properties such as what room it is under, and any configuration properties for the device if any.

    Let us know if you have further trouble.

  • @dbemowsk, Wow! It worked! Thanks so much. Very happy to get to this point.

  • @billgoolsby We were all there at one point. Happy to help.

  • There you have it!
