I am using the klikaanklikuit ACDB-7000B for a while with no problems until a few days ago. The issue: in advanced flows the card is not available enymore (grayed out) I tried removing it and repaired it with Homey, that works fine. I then made a flow with the card “when button is pressed’ something should happen. That works as well. But as soon as I save the changes and refress the webpage, the card is grayed out again. What am I missing? Thanks! ---

When flow cards gray out, it means either the device is unavailable (but that’s not the case here: Homey can’t detect 433MHz devices); Or, the app paused or crashed. I’d say install the KaKu app again from the app store (without removing it prior to that!) [https://homey.app/a/nl.klikaanklikuit/](https://homey.app/a/nl.klikaanklikuit/) ---

thank you for the reply. Unfortunaly this is not the solution. Problem is still there. I noticed the exact same issue with a kaku doorbell. I removed the doorbell (maybe they were intervering with each other) but that did not solve the issue. Any suggestions are much appreciated! ---

Hi Wlt3r, Bummer. FYI KaKu devices only can interfere when they send/receive data at exactly the same moment. They shouldn’t operate on the same channel though. Yesterday I"ve read about disappearing apps, maybe the KaKu app has similar issues. Today I got flows with gray cards (most) as well, also disappearing flows and appearing flows without touching anything. > [@\[APP\]\[Pro&Cloud\] Shelly](https://community.homey.app/t/app-pro-cloud-shelly/765/6275): > > We seen quite some reports that version 3.49.1 is shown as not installed for some users. Please make sure to install version 3.49.2 from the [store](https://homey.app/a/cloud.shelly/) as that seems to fix the issue for the people that have responded to us already. Note that it is exactly the same as 3.49.1, it is just a rebuild with an incremented version number, making a file corruption of some sort the most likely culprit. ---

I don’t understand. You are now refering to Shelly. The problem is with Kaku. Today I found out that all my Kaku wireless bells are not working anymore. The bell it self and the transmitters are grayed out in my flows. (ACDB-7000B and 7000C). Seems like there is no support anymore altough it is still listed in the supported items. ---

Yes I know your problem is with KaKu. The Shellly issue is very similar, that’s why I think something could be wrong with the app system, instead of KaKu only. If you didn’t already, I recommend to contact the KaKu app developer, Athom. As you can find on the app page at app store, they prefer to contact them per [https://homey.app/support](https://homey.app/support).
