Example of V_CUSTOM



  • I want to make a device in Vera UI7 that shows up with arbitrary text. I can't find a pre-defined data type that seems to let me do an arbitrary string, but I see this "Custom" type, but I can't find any way to use it or examples on people using it like I'm talking about..

    I thought maybe it would be as easy as some code like this:

    //define and present
    MyMessage msgCustom(0,V_CUSTOM);
    present (0, S_CUSTOM, "Custom String Sensor");
    
    //and then use it like this:
    send(msgCustom.setSensor(0).set("Hello World"));
    

    BUT.. This doesn't seem to work. I'm only beginning to learn this stuff, so maybe there's a total newbie error in here..

    Can someone point me to an example sketch that perhaps gives the ability to return arbitrary string values to the Vera dashboard?

    Thanks!!

    You have to use dev branch on Arduino and install the following device on Vera (created by @BartE):

    https://github.com/mysensors/Vera/tree/development/LcdText

    It sends V_TEXT message to the node (S_INFO device).



  • AWESOME!

    Thanks a lot! I'm already using Dev branch, so this should be easy to test!

    I guess I know what I'm doing tonight!

  • Out of curiosity....what is your use case for this? [just thinking new ways to expand my system]



  • Well.. My initial use is for a pool temperature / level sensor.. The temp is easy - It's registering as a V_TEMP and working great, but what I want is for the level to say "1.5 inches low" or "2 inches high", etc.. I currently have the value implemented as another V_TEMP, and have my arduino code calibrating the code to show 0 degrees if it's "perfect" and then plus/minus one degree for each inch the pool is high or low, but to have a sensor that is named "Pool level" and the data being "1.5 degrees F" isn't intuitive. I thought about using a distance sensor, but I couldn't get the distance code to work in the first place, and then I'd have to just remember what "distance" is normal (ie: is 0 the "top" of the pool, the the distance represents how far down the water is?) It just seems simpler in many cases to have a few english words displayed in the Vera website.

    Another idea I have is to replace all my "expensive" z-wave door sensors with MySensors on Pro Mini because I hate that the output of the door sensor is just a picture of the door sensor with the "rainbow" on top either colored red, or not, and I have to remember which color is "open". I'd rather have a Vera output that just says "OPEN" or "CLOSED" and I can't figure out any way to do that with the regular sensors so I was just going to build my own..

    I'm sure I'll think of more, but that's enough to keep me busy for a while!
    .. didn't get to try any of this last night as I had hoped.. we ended up going to the town carnival instead... Will try again tonight!
