Setup iConnectFrom Meteohub
Put Meteohub Image onto USB stickThe USB stick you use with iConnect must be a SLC type with a minimum size of 4 GB. Having that, you have to download the latest iConnect USB stick image from here. Uncompress it with "winrar" (on Windows) or "unrar" (on Linux). To transfer the uncompressed disk image (named like "mhiconnect-stick-vxyz.img") as pure binary low-level data to the USB stick you have to be aware that this data has not to be placed into a file system you have already brought onto the USB stick, but that this data includes a complete dump of a storage media with a filesystem included in it. Therefore, just copying the resulting ".img" file onto the stick, as you normally do with files, will not work. You need a special tool for that. LinuxOn Linux you use the "dd" command. Please insert the USB stick into your Linux box and check via "dmesg" what device the stick has been mapped to. In the following example it has been mapped to "/dev/sdj" # dmesg ...

The print out above tells that "/dev/sdj" is the target device. To make sure that the device ist not mounted by some background processes you should manually unmount all partitions by "umount". In the given example this will be umount /dev/sdj1; umount /dev/sdj2; umount /dev/sdj3 When this throws errors about not mounted file systems that is fine. Don't worry. Now it is time to bring the Meteohub image onto the stick. In the example above this will be done by dd if=mhiconnect-stick-xyz.img of=/dev/sdj bs=1M Please be careful with that command. When you choose the wrong "of=" target (i.e. your system drive) this will be overwritten without further notice and you will have to restore your Linux box! As dd has to transport 4GB of data to the stick this will take a few minutes. When finished dd will report number of written blocks. If it reports that not all blocks could be written, something is wrong with your USB stick (may be less than 4GB in size?). WindowsOn Windows you need to download and run a special tool to do the required low-level writing to the USB stick. The tool of choice is "ImageWriter" from SuSE (you find additional information about this tool here). Please download ImageWriter.exe to your Windows PC. It does not need to be installed it is just a small executable to run. Please insert the USB stick into your PC wait a few seconds and then start downloaded "ImageWriter.exe". Wait until a dialog like this pops up: Please select the inserted USB stick from the target drop-down list. Then open the file browser by clicking "Select" button. "*.img" files are not displayed by default so first thing to do is to enter "*.img" as file name. Having done that you will see the file "mhiconnect-stick-xyz.img" on the list. Select and open this file. Dialog should now look like this: Press "copy" and the image data will be written to USB stick. When operation has finished without error, you are done with this step. Please pull the USB stick from your Windows PC. Patch the iConnectPatching the iConnect is done in a few very simple tasks.
Your Meteohub is now ready to go.
Start Meteohub
Read the BlinksWhen boot is going to finish the power LED turns into steady blue. After a while (a minute or so) the power LED goes off and starts a LED blink sequence, that signals the IP of the Meteohub. When signaling is finished, power LED changes to steady blue again. The IP consists of four numbers in the range of 0 to 255 separated by dots. Meteohub signals each of the four numbers by sending for each digit a seqence of short red blinks, where the number of blinks in the sequence represents the digit (1 = one blink, ..., 0 = ten blinks). Dots between numbers are represented by a blue blink. The example below explains how blinking for IP 192.168.0.23 would look like. Meaning of symbols is
192. ___R___R_R_R_R_R_R_R_R_R___R_R___B 168. ___R___R_R_R_R_R_R___R_R_R_R_R_R_R_R___B 0. ___R_R_R_R_R_R_R_R_R_R___B 23 ___R_R___R_R_R
Revert to a regular iConnectWhen you decompress this mage and put it via ImageWriter onto an USB stick and follow procedure as lined out in paragraph "Patch the iConnect", you will revert your Meteohub iConnect system into a regular iConnect again. |
