Thanks for clarification. Reason for asking: Find an easy way to control bricklets using Node-RED via wifi ext 2.0. In the meantime, considering best would be via MQTT.

Hi, is it possible or planned to send direct http requests via the new wifi extension 2.0 to the master brick and read its response? Like: http://ipaddresswifiext2/get.htm?bricklet=laser_range_finder&uid=vbM&request=distance

Thanks a lot for the information - have ordered the board, battery & solar ... lets see how these work with TinkerForge Bricks.

Reflashed the UV Bricklet > working fine now. Appreciate your help - Thanks a lot.

Hi, are there any recommendations of powering a Master Brick with 4 connected Bricklets and a WiFi 2.0 extension via portable power supply, like a Power Bank? Would like to install outdoor where no line power supply is available.

Hi, an UV Light bricklet is used with a Master Brick 2.1 (fw 2.4.0) and the new WiFi 2.0 extension (fw 2.0.0). The value returned from Java method getUVLight() is rather high, like 80000 which results in a too high UV index when deviding by 250. When deviding again by 250 (80000 / 250 / 250), then UV index seems ok. Think this is a bug. Pls advice.

Hi, want to place several moisture bricklets in the garden. 1) any advice what the max shielded cable length is between a moisture bricklet and a master brick? 2) any advice on a waterproof case as outside usage for a moisture bricklet?

Would there be any issues by doing so? The 5V, 5A output should be sufficient I think.

Is it possible to build a Stack with a Step Down Power Supply and 3 Master Bricks = MasterBrick 2.0 + Master Brick 2.1 + Master Brick 2.0? Just curious if the version difference of the Master Bricks will cause any issues?

Checked and working fine. Thanks a Lot

Just a hint The link states the suffix "uv_light" to be used BUT the MQTT JSON response is "intensity" when subscribing to the uvlight: tinkerforge/bricklet/uv_light/x84/uv_light This is not documented.

After using $sudo pip install tinkerforge --upgrade all fine. What is missing, is the a linkt in the MQTT Documentation for the UV bricklet.

Hi, downloaded the latest version of the TF MQTT proxy to be able to use the UV bricklet. After installation received, error message below. Please advice. $ pip install tinkerforge Requirement already satisfied (use --upgrade to upgrade): tinkerforge in /usr/local/lib/python2.7/dist-packages Cleaning up... $ sudo python brick-mqtt-proxy.py& [1] 10498 pi@raspberrypi ~/tinkerforge/mqtt $ Traceback (most recent call last): File "brick-mqtt-proxy.py", line 92, in <module> from tinkerforge.bricklet_uv_light import BrickletUVLight ImportError: No module named bricklet_uv_light

Hi Theo, thanks for your reply but what are the next steps to resolve this issue? Please advice. Much Appreciated.

I am experiencing a similiar error: 2016-03-25 07:11:25.198 [ERROR] [t.i.m.i.MBrickletBarometerImpl] - Tinkerforge Error: Tinkerforge timeout occurred : Did not receive response in time for function ID 1 In addition, from time to time after running openHAB for a while (rTS is the UID for the Barometer Bricklet): - COMMAND no tinkerforge device found for command for item uid: rTS subId: null After resetting the Master Brick and openHAB, the error disappears, but comes back after openHAB runs for a while.

Hi, as a test tried to setup openHAB MQTT displaying AmbientLight bricklet Illuminance BUT nothing is displayed. Any idea what could be wrong?

Thanks for your help. Installed Mosquitto by using: sudo apt-get install mosquitto mosquitto-clients python-mosquitto It is working fine now.

Removed the rule "LED Switch". Switching the LED connected to the IO16 Bricklet Port A0 is working fine.

Hi, connected a LED to A0 of the IO16 bricklet. Using the Brick Viewer and setting the Port Direction to Output, the LED can be turned on and off via changing the value Low to High vv. Tried to setup the same by using openHAB, but the LED is not reacting. Any hints what is worng in below openHAB Testconfiguration having Port A0 as output outa0? #openhab.cfg tinkerforge:hosts=127.0.0.1 tinkerforge:io16.uid=gkM tinkerforge:io16.type=bricklet_io16 tinkerforge:io16.debouncePeriod=100 tinkerforge:io16outa0.uid=gkM tinkerforge:io16outa0.subid=outa0 tinkerforge:io16outa0.type=io_actuator tinkerforge:io16outa0.defaultState=true #items Number TF_AmbientLight "Luminance [%.0f lx]" { tinkerforge="uid=mdh" } Switch outa0 "LED A0" { tinkerforge="uid=gkM, subid=outa0" } #rules import org.openhab.core.library.types.* rule "LED Switch" when Item outa0 changed then if (outa0.state == true) sendcommand(outa0, false) else sendcommand(outa0, true) end NOTE: Instead of true false also tried ON OFF. #sitemap sitemap tf_weather_station label="Weather Station" { Frame { Text item=TF_AmbientLight Switch item=outa0 } }

Hi, pls advice where to find the openHAB binding for the UV Light Bricklet.

Hi, noticed that the brick-mqtt-proxy is not by default installed on the red-brick - using image 1.8 What is the best way to install on the red-brick the brick-mqtt-proxy and ensure it is automatically started during boot?

Just a bit of fun what can be build with MakerBeam . Smartphone Holder = rather handy when developing Apps or watching Newsfeeds and the likes.

You're spot on. Good to know. Solved. Thanks for swift reply.
