General Discussion

@Nicola-Reina Let me know how things go, and if you could use any help. I am sure I could spare some time for it.

@bjornhallberg Have a look at this http://ing.dk/blog/hvilken-elmaaler-har-du-120890#p391493 There is a schematic of a IR head for the kamstrup meters. Might be usefull for your meter as well.. If you're up to reading danish, there are a couple of sites where the author of that blog deciphers the kamstrup protocol.. like this one http://ing.dk/blog/kamstrup-meter-protocol-127052

Thanks kalle! Yes. Could not find it for. Days ...

@Avenger If you run e.g. an MQTT broker or a domotica server (like OpenHab) it is possible to store sensor data and have it retrieved by actuators (e.g. a display) on request. Did you consider such a setup?

mmm.. Ok - thanks Hek. I was doing similar by having multiple copies of the Arduino IDE - one with 1.3 libs and another with 1.4 but ive recently started using AtmelStudio with VisualMicro plugin. I wonder if i can change within there without restarting the IDE completely...

You are very welcome of course. There are more suppliers but this one sells many many types, price is ok, quality is very good and shipment rocks :)

I think that unless you want to transfer a lot of power, Ethernet cables, Cat 5/6 are the best choice. I am wondering if this is the right forum though, MySensors is more about wireless communication.

@marceltrapman, using a smart and nice etching process is never something people have an issue with. The point people are trying to make on this thread is that if you can achieve the same results by using a small tank and an inexpensive chemical, why go for an expensive process. There are so many different etching processes available that you can choose from which are cheap enough to be used by anyone. Etching does impact the quality of a PCB but as long as you’re not making expensive antenna PCBs, usual process work fine. electronics assembly

@daulagari There are some on AliExpress. A bit cheaper than Antratek but not much. Not 100% sure you get the Uno shield adapter but it seems so. Still no big deal with the price since we only need one gateway.

Looks nice - would be great as a scene controller too.

Tried again with Firefox and now things are working. Problems solved!

Cool. But I can't find much info on their website.

@hek I would reck this is no time flat. That thing would have to be water proof for me...

Good to see there are also MQTT client libraries for Arduino (Part 2) Parts 3 and 4 are about a controller / graphing solution. For sure nice, but I personally like to keep my data on my devices.

@hek Oh so those SPIs can be connected in parallel. The challenge is that the vias for MISO and MOSI are hidden under the screen so wiring is tight to say the least. I have two extra microviews without bootloader and flashing that requires using those internal vias https://learn.sparkfun.com/tutorials/installing-a-bootloader-on-the-microview But even doing that might be out of my league. I could give one micoview free to someone in return for flashing them with bootloader and solving the issue of soldering the wires for the radio (SPI) so that the display still works.

@Vodden I also am doing a Reno and have the option of putting in cabling throughout the house. As I already have POE camera's to install I have a POE switch. So was looking into options of at least powering the sensors with POE. I have based my sensors around the Nano so wanted to convert the POE output to USB voltage and ideally plug the sensor in using a USB cable. After some research this seems to give me the POE to 5V for $13 http://www.pccasegear.com/index.php?main_page=product_info&products_id=26091&cPath=1657&utm_source=googlebase&utm_medium=cse&utm_campaign=export_feed#googlebase The sensor package itself will still be cheapish as most of the arduinos will be running more than one sensor. It is also cheaper and easier than using an Ethernet shield and having to hack it onto the Nano's All I need now is to find a cable with a jack on one end to a USB mini. Anyone have any ideas?

@hek said: http://www.bitreactive.com/concurrency-in-iot/ If it is the same I used them when I programmed in Cocoa. At first a 'bit' difficult but once you understand quite nice. Don't know if it is the same though...
