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

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.

Setup:

• Raspberry Pi 3 with latest Raspian (Jessie)
  
• Master Brick 2.0 with Temperature, Humidity and Barometer Bricklet
  
• openHAB 1.8.1, TinkerForge Bindings org.openhab.action.tinkerforge-1.8.1.jar and org.openhab.binding.tinkerforge-1.8.1.jar

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.

Hi,

tried to install on the RED Brick via Brick Viewer > RED Brick > Programs.

After creating, receiving following error:

The red brick configuration file (tfrba) is attached.

Any help appreciated.

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.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.

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.

Hi,

where to find the latest version of the Brick Viewer 2.3.3 for the Raspberry Pi?

Wanted to use the new OLED 64x48 bricklet connected to the Raspberry Pi, but version brickv 2.3.0 states unknow device.

Tried below to update, but still brickv 2.3.0:

wget http://download.tinkerforge.com/tools/brickv/linux/brickv_linux_latest.deb

sudo dpkg -i brickv_linux_latest.deb

Have tested and is working fine. Thanks.

Consideration

To check by the application which button is pressed, the JSON string is parsed. The keys checked are "0": ... "3":.

The only caution is that the JSON string does not contain the word Button or LCD20x4, so in case "0": ... "3": are also used for other messages then a conflict is the result.

Hi,

for the LCD20x4 how to control the 4 buttons using the MQTT Proxy, e.g. when pressing a Button an action is triggered using publish and how to subscribe.

Works with correction:

Char range is from \u0008 to \u000F

BTW: Have written (in B4J) a small utility http://www.rwblinn.de/iot/tflcdcharmaker.htm helping to define Custom Chars for the LCD Bricklet.

One more related question is how to write a custom char. The standard table does not contain arrow up. Question is how to translate the custom arrow up from bytes to the hex value to be displayed as asked previous.

* ``character[0] = 0b00000000`` (decimal value 0)

* ``character[1] = 0b00000100`` (decimal value 4)

* ``character[2] = 0b00001010`` (decimal value 10)

* ``character[3] = 0b00011011`` (decimal value 27)

* ``character[4] = 0b00000100`` (decimal value 4)

* ``character[5] = 0b00000100`` (decimal value 4)

* ``character[6] = 0b00001110`` (decimal value 14)

* ``character[7] = 0b00000000`` (decimal value 0)

Appreciate your help
