I’m using KLF 200 and Velux binding Problem is, that this binding stop working and I don’t know why. KLF 200 I can see on the network : ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/2/5/259cd6b7dc7634170615ed3abc31f0121e899b9e.png) also I can ping a device: ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/a/e/ae12124b4e00446dacf1abe4f40f8a11daddf1c6.png) also I can connect via wifi directly to web page of the device but under openhab I have a error : ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/e/4/e487e323b719dcda0a1f378e5fbfe85c7949475b.png) configuration is the same how it was working before Please how to trace a root cause of the problem ? Thank you ---

Did you set the correct password? It is not the default password „velux123“ according to the binding‘s documentation. If I remeber correctly it is the web user‘s password. ---

yes, it’s password from the back side of the unit ---

Hi Alex, The KLF200 has the annoying habit of going zombie every now and then for quite a lot of us. Try disabling the bridge thing, unplugging the KLF200, wait some time (10 seconds, or a bit more) before plugging in the KLF200 again. Wait a little more (solid green light on the KLF200) and enable the bridge thing again. I now have a rule thet does this automatically with the help of a smart plug. ---

ok, I will try restart. Please can you share your automatic restart solution ? ---

ok, thanks. Is there any other way how to control velux roller shutters without problematic KLF200? ---

It can also be done in blockly ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/2/d/2d3255fb1e407950ed76973b5887511b3b71fa24.png) ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/2/5/258e6917cd7bb1b40096c3e788dc602945f225c1.png) Just change the name of the bridge thing and add the name of your switch item… AFAIK, the WiFi connection of the KLF200 closes after 10 minutes, therefore I set the second timer to 11 minutes. ---

> [@alda1](#): > > means if wifi is running LAN connection isn’t possible ? Correct. If you enabled the LAN connection, WiFi will be available for a short time after reboot and then shuts down. Communication is possible over LAN only then. ---

LAN must be enabled, is used for the “data” communication Wifi I can set off for always (if block LAN), because is used only for direct setup via web page ---

oh, thaks. Means every unexpected power shut down can make a big trouble with Velux bridge ---

ok, clear. Problem is, it looks like when bridge is in the error, is still trying connect with KLF200 and finally will block LAN communication with openHAB at all. ---

> [@alda1](#): > > will block LAN communication with openHAB at all. This is the so called zombie state. The KLF thinks it still has a live connection from OH and it won’t accept any other connection attempt from OH. Whereas OH thinks the connection is down so it retries making a connection. The only solution is to disable the bridge in OH, then power cycle the bridge, then re-enable the bridge in OH. ---

Thanks all for help. Now Velux Bridge is running again. Now I must implement automatic stop of the bridge when communication stop working ---

only one proble is that rule to disable a bridge doesn’t work for me I did it as I found : ```auto sendHttpPutRequest("http://localhost:8080/rest/things/velux:klf200:192_168_1_55/enable", "text/plain", "false", headers, 1000) ``` But Bridge is still ONLINE ---
