    • RE: Size of icons in forum mobile view

      OK, issue reported: https://github.com/NodeBB/nodebb-theme-persona/issues/244

      ToniA created this issue in NodeBB/nodebb-theme-persona

      closed Size of class 'fa fa-arrow-circle-right' is awfully small on mobile UI #244

    • RE: Recommendation: power supply

      @Dwalt But if the idea is to run some actuator (like relay) on it, it must be on all the time.

    • RE: Node are not receiving messages from domoticz

      8 MHz Arduinos absolutely need to use lower baud rate than 115200. The baud rate is generated from the internal clock, and at 8 MHz 38400 bps is the highest baud rate close enough to the standard.

    • RE: Heatpump controller

      Nice to see that my little HeatpumpIR library made it all the way here 🙂

      I'm also quite new to MySensors, I actually just started today, I've had all the necessary hardware on my table for some weeks now... My goal is to power a (physically) small MySensors device directly from the Panasonic heatpump, and hide everything within the indoor unit's covers, and have it fully controlled by Domoticz. There's quite a bit of work to do, as for example Domoticz does not have a suitable devuce type yet.

      And how about MySensors, I'm still quite a newbie on the messaging schema... Is there a schema which could be used to communicate all of these within the same message:

      • ON/OFF information (0 or 1)
      • Temperature information (integer from 8 to 30)
      • Fan speed information (integer from 0 to 5)
      • Mode information (COOL, HEAT etc. i.e. integer from 0 to 6)

      What comes to Daikin, it would probably be quite easy to add it into the HeatpumpIR code, provided that I could borrow the remote controller for a while. Or, if somebody else could decode the protocol.

    • RE: Power Pro mini 3.3v from usb ?

      You need to connect it using a 3.3V USB to serial adapter.

      Something like this: http://www.ebay.com/itm/3-3V-USB-to-TTL-Serial-Cable-FT232-Chipset-FTDI-USB-Cable-Adapter-Computer-Cable-/181870867906

    • RE: Heatpump controller

      Interesting... I took a look at mharizanov's work, and I think I might have a decoder for the protocol here: https://github.com/ToniA/Raw-IR-decoder-for-Arduino

      Would you try if this correctly decodes the protocol? I would also appreciate some full outputs of successful decode, together with the explanation of the state the remote control shows after the button press.

      If the decoder is correct, creating a Daikin module for the HeatpumpIR library will be a piece of cake 🙂

    • RE: Arduino & Microsoft Competition

      Really interesting, maybe I could build something cool around the Arduino HeatpumpIR (https://github.com/ToniA/arduino-heatpumpir) library I've been building. Right now I'm integrating it with Domoticz (http://www.domoticz.com/forum/viewtopic.php?f=34&t=7179#p69647).

      I'm an ex-Microsoft employee from Finland (resigned about a month ago).

    • RE: Battery operated actuator

      @riataman, have you looked at this: https://github.com/mysensors/Arduino/tree/development/libraries/MySensors/examples/HeatpumpIRController, it's based on the HeatpumpIR library I've written? I just added a few new heatpump models yesterday and today into the library...

      Anyway, in my project I'm currently using Arduino Nano + NRF24. I placed this inside the indoor unit's covers, IR led next to the IR eye of the unit, and I even stole the power from the air conditioner, as its logic is running on +5V, which is conveniently the same as the operating voltage of the Nano 🙂 Of course I can't recommend anybody to do that 🙂

      I just got some Sensebenders this week, so I'm trying to build a way smaller device for the other A/C unit I have.

      Just got my Sensebenders this week. I can confirm that the HeatpumpIR library works also on the Sensebender 🙂 Nice...

    • RE: Battery operated actuator

      This is what I'm using as the control interface: http://www.domoticz.com/forum/viewtopic.php?f=34&t=7179#p69647

      It's still under work, but I should be able to have events running on Domoticz, like turn on the A/C if it gets too hot inside the house etc.

    • RE: What is a good value for a watch dog timer?

      Also the stock bootloader is broken so that in reboot, it sets the watchdog timer to a very small value (so that a reboot would happen before the sketch has done 'setup()'), but does not turn off the watchdog it it was enabled in the sketch -> eternal reset loop if you ever reboot from a watchdog-enabled sketch.

      Optiboot, MYSBootLoader etc. would work fine.

    • RE: Has anyone tried software reset of an Arduino?

      For whatever strange reason, the Arduino stock bootloader is broken, so that it will not disable the watchdog on startup, causing just an infinite reset loop. I'd recommend updating the bootloader with something like MYSBootloader or Optiboot.

    • RE: AC IR code decrypting

      This is what I have done as a hobby so far: https://www.openhardware.io/view/41/Heatpump-airconditioner-controller

      There's no Gree support in the HeatpumpIR library, though.

    • RE: AC IR code decrypting

      @dpressle said:

      @ToniA can you elaborate?

      Yes, on my AC IR decoder sketch I have decoder modules for different heatpumps. Like this:

      https://github.com/ToniA/Raw-IR-decoder-for-Arduino/blob/master/MitsubishiElectric.cpp

      So, write a new one, and add a call to it into https://github.com/ToniA/Raw-IR-decoder-for-Arduino/blob/master/rawirdecode.ino#L315. First you need to write a condition to recognize the protocol (like, from the first bytes + length etc). Then just start adding functionality, like decoding the temperature, then operating mode etc.

    • RE: AC IR code decrypting

      How about writing a new decode module into Raw-IR-decoder-for-Arduino? I find it very useful in trying to figure out how a certain A/C protocol works.

    • RE: incomingMessage is not initiated on relay sensor

      The experience I have is from running the serial gateway on Sensebender (which is a 8MHz device, running on 3.3V). It just didn't work at all, and as soon as changed the serial speed to 38400 everything was just fine.

      http://wormfood.net/avrbaudcalc.php?bitrate=300%2C600%2C1200%2C2400%2C4800%2C9600%2C14.4k%2C19.2k%2C28.8k%2C38.4k%2C57.6k%2C76.8k%2C115.2k%2C230.4k%2C250k%2C.5m%2C1m&clock=8&databits=8

      It also doesn't matter whether you connect through USB or RS-232, it's still the same problem. Another 'nice' finding was that Arduino Nano has a hardware problem, it's not discovered as a USB device when Raspberry boots up. I had really interesting times when trying to use it as the serial gateway, works fine when plugged in when Raspberry is running, but it's lost on every boot.

    • RE: Is it possible to connect a Pro Mini directly to Raspberry Pi GPIO for Gateway?

      It's the /dev/ttyAMA0. See this: https://www.raspberrypi.org/forums/viewtopic.php?p=139945

      Domoticz runs as root (which is a really bad thing IMHO), so it has no problems with this.

    • RE: Is it possible to connect a Pro Mini directly to Raspberry Pi GPIO for Gateway?

      I've done the same with SenseBender, so it should work with Pro as well. You only need 4 wires, GND, Vcc, RX, TX.

      If it's a 3.3V model, it runs on 8 MHz, so you need to set the serial speed to 38400. At 115200 the serial speed is too much off to work reliably.
