I will check and post my on and off codes later tonight if I can find the time. I have only access to the remote until next weekend so I won't be able to actually verify anything until then. :s

@Moshe-Livne I agree that the remote must be sending not only the "on"-command, but the whole state as currently displayed on the remote, because if you point the remote away from the pump, make some changes, then point it at the pump and make another change all the changes will come into effect. Then again, the pump itself (mine at least) does remember its last state because it can wake up after a power outage with the same settings as before the outage.

Hi,

I've built the IR sender/receiver sensor and I am alble to receive and send codes without problems when using codes for my Sony receiver. However the main reason for building this particular sensor is that I would like to control my Mitshubishi Kirigamine air to air heat pump. The remote model for the pump is KM08A.

I can't find any codes on the net for this remote som I tried receiving the code when pushing the on/off button. I thought that I could capture the code and then use it to send the command I wanted. This is what I got via the serial monitor:

But how do I use this? Can I convert it somwhow to the 0x00000 format used in the sketch? I appreciate any thoughts and suggestions!

@phil-pritchard No, not really. As I've mentioned tinkering with hardware is new to me so I don't actually have any knowledge of what exists and whats possible from that side of the table. Would you like to expand on your thoughts?

I've ordered a bunch of these hall effect sensors: http://www.ebay.com/itm/221649135732?rmvSB=true

Thanks @sparkman for once again nudging me in the right direction!
I went trough the code in my sketch a couple of times commenting out various sections and suddenly the sensor started functioning correctly. So I checked that function closely and noticed that I was out of bounds in a for-loop. that stupid NUMBER_OF_CURRENT_PINS +1 . That +1 had accidentally stayed there from an early version of the sketch. Correcting that, my sketch seems to load without problems - go figure!

@tbowmo It was just a thought I came up with and thought to share my idea and arguments.
I think the Sensebender Micro is great especially if you would like to monitor temperatures (which of course many of us wants to), but I just think that a less expensive, light option (that would be available to order... ) could appeal to many. Great that you have requested a quote!

@Sparkman
I tried powering the Megas radio from a Nanos 3.3V pin and GND. The Nano is working fine as a sensor by itself, so I guess the radio gets enough power from it. However, this way I only got "check wires" from the Mega...

Just a thought; if it helps, I'm defining these pins for the Mega in my sketch, but I don't see how that could affect this particular problem...

const int relayPin[] = {22, 23, 24, 25, 26, 27, 28, 29};
const int currentPin[] = {A0, A1, A2, A3, A4, A5, A6, A7, A8, A9};

@hek said:

That's the old A10. It would probably work but A20 has some firmware fixes and more tests performed on it.
I have nothing to say about the price. It is the same as for A20.. As you can see it is the most expensive part on the micro board (30% of it's price).

Would you consider a Sensebender Micro Light-version without this component? i mean, if it's 30 % of the price, not available and not imo a critical component (you could always add your own humidity/temp sensors), there are quite a few reasons why a light version would be tempting. At least to me.

Thanks for the suggestion, @Sparkman !
I have just the radio connected for now, but still getting that "version mismatch"-error. I will try getting a separate 3.3v power to the radio tomorrow and see if that would help.

Tried powering the Mega from computers USB 5V, and two different 12V DC adapters - still getting version mismatch. Anybody knows what's going on?

Finally found a combination that worked with the mega as a sensor. Here is the pin mapping if it will save time for anyone:

9 CE
10 CSN/CS
52 SCK
51 MOSI
50 MISO
2 IRQ

Doesn't require any config changes, but I am currently getting some "0;0;3;0;9;version mismatch" in serial monitor. Have 10 uF cap on the radio.
