Is there anyone using MQTT as gateway for connecting to openHab running on another Rpi. If so please help with any links, post or any information to direct me on the right path.
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
thx for reply
yes dragino HE works like yun I think.
for linkit as the product seems new, there is a little bit less docs. but I will see, price was so interesting that it was too much tempting lol.
I will tell you what I can get...
for fun, I have not presented yet, but I have a board in progress for raildin : 8x relays + 8inputs for yun and I added ethernet connector+hub usb chip
@tsunami My setup is max 50m radius and 433MHz standard power RFM69s so a small 1/4 wave whip works reliably even from a below ground pump chamber 10m away.
Your 915MHz at 200m SHOULD work on 1/4 wave if obstacle free line of sight, but you could try a 2.4GHz Wifi router at one location and use a mobile at the other to test if you can see the router. I can see at least 3 neighbouring routers identified on my mobile from over 40m away through masonry, 10 on the laptop, so it's a simple enough test.
If you can see the router on either, 915MHz should be rock solid with a simple whip and no need of directional antenna.
@marceltrapman
when you change the BAUD rate setting in the source/config file to something lower/other you can also use 3.3V Arduinos as (Serial)Gateway. Of cause your controller needs also to be told about the lower BAUD rate.
Check out http://wormfood.net/avrbaudcalc.php?postbitrate=9600&postclock=8 for an overview of Clockspeeds (usually 8MHz for 3.3V and 16MHz for 5V types) and coresponding BAUD rates.
