Hardware

@Yveaux no no no.... I didn't explain myself well I guess. The mysensors node "press" buttons on a universal remote control, see http://forum.mysensors.org/topic/1662/air-conditioning-hvac-control-work-in-progress The universal remote is powered from the arduino as well. As long as it is powered it remembers the settings for the aircon. once I power down the node the remote powers down as well and has to scan to find the right settings.

@gregl , why didn't I think about that! Great tip! I might buy the joint I linked to in my first post but then use a standard bolt and drill it open for a standard DS18B20 water proof temp sensor which I allready have laying around is really simple solution. Thanks! Will try to get back with pictures when this is done... ☺ Henrik

@Viper_Scull Domoticz supports V_VARs, just not as a viewable or modifiable value on the controller. It will store and return the V_VARs values for the sketch, nothing more.

@Sparkman thanks man, i finally got 2 nrf24l01 just for testing and now i would like to test an example for a dht11 and 2 relay, can you help me? do i still need something else? i'm trying to follow TimO example but without luck. I have an arduino mega and uno too, an ethernet shield and 2 nrf, a few sensors. I would like to make a serial gateway or a ethernetgateway and to connect dht11, 2 relays and a sct-013-00. can anyone help me? any help would be kindly appreciated. thanks all.

@blacey oh i see. My pro mini has vin written on the raw pin so i mixed it up. Thanks!

@Moshe-Livne Sweet. thanks.

@Moshe-Livne said: In what way is it better? The datasheet states that to wake an ATMega from sleep from a PIN0/1 interrupt it should be configured as LEVEL interrupt, not CHANGE (second parameter to gw.sleep() ) It is likely to work when configured for CHANGE, but under certain conditions the interrupt may not be detected correctly by the ATMega.

Please send an email to info@mysensors.org with your ideas and questions..

@Ivan-Z Thanks. I have seen this in another thread. Decided against it for several reasons. This sensor should be asleep 99.9999% of the time. According to the legends this battery should power my sensor for years.

Thanks. I tried it now and it is working without any problems.

I think the trick here is that they just announced a $40 4.3" monitor and you’ll have to spend additional cash for the VGA or HDMI adapters. http://ardevon.com/2015/07/chip-the-worlds-first-9-computer/

@tbowmo nope, still no go. strangely, when i disconnect the arduino from the computer (so it is not powered), it creates a short after a few seconds and the bell starts ringing continuously.

@Moshe-Livne said: @Sparkman would have been nice if they could charge from motion, wouldn't it? :laughing: That would be great:smirk:

@AWI Yes i am. but there is mistake in the picture the R3 is connected between Pin 3 and VCC, not ground (pull up resistor). Then that leaves me hanging a bit because that is way more than I will be comfortable with in terms off battery changes. Any suggestion what to do?

My unmodified iBoard is working for months now as a gateway without problems. Initially I had some problems with hanging connections. But these problems disappeared after replacing my 1$ power supply with a 3$ one. The iBoard needs a decent power supply.

@Moshe-Livne there already is a 4u7 capacitor for the radio, on the sensebender. in theory, it could be used with cr2032 battery, but I doubt that it would last long..

@AWI totally understandable! I am a bit relived to hear that actually. I own a reasonable (I think) multimeter - not the cheapest from aliexpress... it is reasonably ok but everyone is so hushhush about the accuracy. I even ended up asking some multimeters companies what is the *&%&% accuracy and stop giving me all sorts of equations to solve!!! It reminds me of my other hobby, woodworking. You can do almost anything to a really good degree of finish with couple of hundreds $ of equipment BUT (and its a big capital BUT): You need to know what you are doing You need to carefully select this equipment and usually you gain the insight only after spending couple of K$ on useless hyped things. You need to have the confidence required it does take more time and can end up less accurate. Thanks for this... now I can use my multimeter with more confidence

On of the sensor is the distance sensor that looks like Wall-e. I havent started to test with battery yet but what i read it doesnt sound like you can power a simple sensor for so long with batteries? //Mathias
