    • Indigo 6, Applescript, & Temperatures: can't get values

      I'm trying to write an applescript to send temperature values from MySensors temperature to RRDTool. I have successfully sent other variables to RRDTool and Indigo is correctly reading the temperature of the sensor, but I can't seem to get the applescript to read the temperature value of my sensor device.

      Specifically, it seems that when I use any variations of this:

      tell application "IndigoServer"
        return temperatures of device named "Temperature"
      end tell
      

      I get an empty list:

      {}
      

      I have tried setting the value as a list and getting the first value from the list as well, but no dice.

      Is there something different you have to ask the plugin to "return" in order to get the temperature value? I used this page:
      http://www.indigodomo.com/static/www/html/02300_indigo_as_dict.html
      and started going down the list of possible device properties but couldn't get the temperature value to return.

      @BulldogLowell Yes, all is working, thanks. If you want to use this code for reference it is fully functional.

    • RE: [SOLVED] Multiple devices demonstrating erratic behavior

      So for those who may be wondering, here are a couple things I learned working with multiple sensors + relays:

      • All radios need capacitors because the 3.3V on the arduino is not sufficient
      • Extra devices and arduinos that appear in your device list can be cleared out - remove the device and re-scan, and it should sort those problems out. I had mysterious sensors appear and refuse to leave until I did this.
      • Keep track of and double check your pin numbers.
      • (Clearly) don't use delay(), instead use millis()
      • I did some of this piece by piece instead of repeating a function because I was trying to diagnose problems. It could probably be cleaned up but it successfully has seven different devices being controlled and functioning properly.

    • RE: [SOLVED] Multiple devices demonstrating erratic behavior

      @hek ok, I think I solved some of this. The extra sensors were coming from previous trials and errors. I removed the device and added it again, and bingo, no extra relays.

      As for the relays not responding, I found an error in the code AND I think the motion sensor is getting stuck in a loop. When I activate all sensors there is still enough power for the relays to go. The problem is when I uncomment the code monitoring the motion sensor, everything becomes stuck again. There's a problem with the code to continuously monitor the motion sensor:

       float state = digitalRead(DIGITAL_INPUT_SENSOR);
        if (state == HIGH) {
           if (state != lastMo) {
            gw.send(msgPIR.set(state?"1":"0"));
            lastMo = state;
          }
          previousMillis2 = currentMillis;
        }
      

      and here is the current version of the code:

    • RE: [SOLVED] Multiple devices demonstrating erratic behavior

      @thermistor1 I should add that the I want the relays to start with pins HIGH which makes the relays OFF every time I start the arduino. There are appliances that I want to remain off unless the pin goes low (e.g. the home router is ON when the pin is HIGH and I don't want it to reset every time the arduino is energized).

    • [SOLVED] Multiple devices demonstrating erratic behavior

      First, I'm using a Mac 10.6.8 with Indigo 6 and the MySensors plugin (newest Arduino software, two Diecimillias with 328 chips). I have two arduinos that communicate with each other, and I have caps on the radios for both so they are reliably communicating.

      One of my arduinos has multiple devices attached from a previous project and I'm trying to code them over to MySensors. Specifically, there is a Temp/Humidity sensor, a PIR motion sensor, an RGB LED to indicate what the arduino is doing, and 4 relays. I can get each device/sensor to behave properly on its own, but when I try using them together I get strange behavior, such as:

      1. A build-up of messages or something in a buffer somewhere, so that it takes the Indigo plugin a couple minutes to get through the messages (it processes about one every 10 seconds, and I'm sending 1 to 3 messages every ten seconds. In the code below, after all the devices are registered, the temperature and humidity update once and then the only updates I get are from the PIR sensor.

      2. Extra relays - the plugin mistakes two of the sensors for relays, despite manually registering only 4. This is not a problem in the code below but has happened with previous attempts, I THINK I fixed it when I turned the gw.begin node to false but I could be wrong.

      3. Erratic relay behavior/unreliability. The wrong relay or state is sometimes triggered. With the code below, the relays are not even responding.

      Below is my code, I'm hoping someone can give me insight on why I may be getting such behavior.
