[velux] failed to connect to second roller shutter

[bodo1987]

Hi,

I have 2 roller shutters installed. Both of them are succesfully connected to the KLF200 and I can see that both can be controlled by the KLF200 (using the identify button in the webfrontend).
I integerated the KLF as bride Thing in the GUI and I also added the support thing as well.
After searching for new things in the inbox, I got the first roller shutter without problems. I linked an item and it could be controlled as expected. However, I was not able to discover the second roller shutter. Neither automatically, nor manually.

The problem with the manual add is mostly because of the lag of the serial number. Also, I am not so sure if this would help anyway since i ofter read, that the serial number is identically if you have original velux roller shutters (as i have).

So, I tried to play around with the name of the roller shutter as I assigned it in the KLF GUI. There I have two different names: D05 and D07 for the roller shutters in the rooms D05 and D07. But also this was without success. Please be aware that I also used the 00:00:...:00 serial number as mentioned in the documentation. More things I tried as names are:

• '#0
• 'Fixed URL for "how to contribute" #1
• 1

All of them without success.

Next thing was to have a look in the log. I put it on TRACE level. (see atachment) Also here, I can see only one device popping up with bridgeIndex 0. As i read elsewhere, other devices should be added with incrementing bridgeIndex, but for some reason that is not happening in my case.

So, for the time beeing, I am asuming a bug. Or is there any hint of what I could still try.

I suppose the roller shutters are Somfy devices?

EDIT: if they are Somfy then you use 00:00 etc. as the serial number, and identify the thing in OH via its name. But if they are Velux you use the proper serial number, and the name is irrelevant.

I use the standard Velux rollershutters with solar cells as energy source.

I also tried to play around with some bridge options and indeed, I can claim success.

What I did:

• deactivating the "Massenabfrage" option (mass querries in english?)
• without that option, I could see a second roller shutter from time to time during the discovery porcedure
• after some tries, I also got a second serial number
• with that, I could agin activate the "Massenabfrage" option
• I had to reboot, since the binding kept going to throw connection erros
• remove the names in the roller shutter things
• deactivate everything and activate it aging

Success!

So all together, the binding finally seems to do what I was expecting. However, there are some major stability issues and also there is a problem with the discovery procedure. I'm not sure if this is a general problem or only something related to my setup, but at least if there are more complaints, I can only encurage you to have look on this. If you need more logs of any kind, tell me. I'll try to help, if I can.

Best regards

As the isssue seems to be resolved I close this for now.
If there are still improvements that can be made to the discovery proces, please create a new issue with specifics for that improvement.
