My Project

@ServiceXp said: @samppa I'm probably miss-understanding you, but wouldn't the electric heater be 100% efficient? In other words, for every watt you consume you would be outputting in thermal energy? I realized in many area's** it's not the cheapest form of heat**, but I think it's 100% efficient? Yes, but in this case the definition of efficiency that is interesting to know is the heat exchange efficiency i.e. how much of the heat dissipated is preserved and transferred to the fresh air influx. The idea is to save energy and avoid heating with electricity. So the heat in hot air exhausted from the room is re-used to warm the cold outside air.

Thanks for the reply. I am not looking to use an LCD, although that may be the best solution. For now, I plan on creating a simple set of LEDs and buttons. I have looked over the code, and was wondering which part of the code is retrieving the status of a sensor? What if I have multiple motion sensors, how would I retrieve each unique value?

@samppa yes, but you saw the little point functions your arduino is very capable of, yes? if you post your attempt at a sketch to control your fan (or even pseudo code) we can certainly help you code it up for Vera.

Ok, thanks. I'll try to use some extra repeaters then. Boozz

Thanks hek, Did it a bit different, but probably with the result i wanted. In the repeaternode sketch I used the following line: gw.begin(NULL,4,true); This created a repeater node with node-id 4 (just an arbitrary number) In the Dallastemperature example I used: gw.begin(NULL,5,false,4) This created the sensor node with id=5, talking via repeaternode 4 to the serial gateway. This works. See the info from the temperature sensor being relayed to the serial-gateway. I haven't tried the method you suggested yet, but this sounds interesting of course. Wiil do that after Christmas I think. Boozz

No, youre right, that wouldnt work for battery powered. I chop the ends off old cell phone chargers and try to keep a room's sensors down to a single box. The only one I've considered being battery powered is the "Mailbox opened" one but thats another project. The polling is really just to allow getting realtime data when you want it. If I think about it more, Ill probably leave it out. I was just thinking out loud near the end.

Well I changed the connection type for the sensors due to the above issue. [image: 20141202_183743.jpg] Tested and again after 2.5 days, it locked out on a sensor com error. So after some thought, I realized, (not sure why I didn't before) the system is not going to be 100% bullet proof, so instead of moving to a hard fault, I recoded the error handling section of the sketch to attempt to handle the occasional hiccups in reading the sensors. Pushed new sketch to Github and am testing now. It will interesting to see just how many times the readings fail. I shall see.....

Hi have a look at nodered http://nodered.org. Easy to setup work flows and can run on any platform.

@dzairo there is a nice PinChangeInterrupt library that you may want to look at.

I have only used that radio for one node so far - one of the LCD clocks. Its only about 30ft from the controller but it does go though a couple of walls. Communication is pretty much 100% at that range. I used the larger antenna radios for the longer distances - e.g. the garage which is 50ft or so and about 4 walls but its very consistent. Rich

@Yveaux you are right, the worse is when I open it... I see this is not waterproof at all and... [image: IMG_20141019_204454.jpg]

@epierre had a quick look at the data sheet. The sensor has a 64 bit shift register which uses a clock signal and serial input. You need to clock in the 64 bits one by one and generate a clock pulse for each bit. Then read out each bit as an analog value on AO, and continue with the next bit. This thing is not i2c, spi nor i2s (audio only), but defines its own protocol. Connect your logic analyzer to clk and si if you like, but you also need an oscilloscope or so if you want to see the analog output values.

I am hoping it will happen soon. There are more and more zigbee only products that would be really nice to integrate into Vera.

Update: Wind up having to buy a oscilloscope to try and diagnose a problem I was having and wound up reworking the transformer board a little. I installed 5 caps in an attempt to clean up the output. 4.7uF/400V Cap between pins 22 and 26 on transformer. electrolytic 470uF/50v Between 5vd Output (electrolytic) 47uF/50v Between 5vd Output (electrolytic) 10uF/50v Between 5vd Output (electrolytic) .1uF/ (ceramic) Installed at the screw connector on the main board (for best results)

You may look at the node js controller. It has database support. https://github.com/mysensors/Arduino/tree/master/NodeJsController Also check out the controller section of the form. http://forum.mysensors.org/category/3/controllers
