I searched the Fibaro forum for this problem with Walli switches, but did not find anything about it. But I know a case where a user had the same problem with several Fibaro RS3. The user had even contacted Fibaro, but without a satisfying result. These are the corresponding posts in the Homey and Fibaro forum: > [@Fibaro Roller Shutter 3 - Ohne Funktion - Pulsiert nur Blau](https://community.homey.app/t/fibaro-roller-shutter-3-ohne-funktion-pulsiert-nur-blau/63037): > > Hi. Vielleicht kann mir jemand helfen. slight_smile Ich habe 20 x “Fibaro Roller Shutter 3” seit rund sechs Monaten im Einsatz. Sie liefen zunächst einwandfrei. Seit ein paar Wochen steigen immer weitere aus. Mittlerweile funktionieren 7 nicht mehr. Weder per Schalter (Knebelschalter), noch über den Homey. Auch in der Developer Ansicht reagieren die 7 zu 98% nicht auf „Test“. Ganz selten bekomme ich mal ein „Node is reachable“. Ein “Klickgeräusch” wie sonst, ist ebenfalls nicht zu vernehmen. … > **[Fibaro Roller Shutter 3 - Without function - Pulses only blue](https://forum.fibaro.com/topic/59687-fibaro-roller-shutter-3-without-function-pulses-only-blue/#comment-252497)** > > Hi.

Sometimes the blinking and color do have a meaning, check the user manual of the device to find out what is wrong. ---

So I did, I got 2 new Walli controllers back, put off the power, installed the switches and they are operational again, but guess what. Due to the power cat, another Walli controller has the same issue. I found out on the Fibaro forum that people had the same issue and they solved by lowering the sync frequency from 1500 to e.g. 300. But where can I lower the sync frequency? Is that a Homey setting or a setting within the Fibaro Walli Controller? ---

In my case it is the Walli Switch in stead of the Walli Dimmer [Walli Dimmer don’t stop blink blue - Community - Smart Home Forum by FIBARO](https://forum.fibaro.com/topic/48761-walli-dimmer-dont-stop-blink-blue/#comment-198879) ---

I have no idea what he means exactly and I used a Home Center 2 myself in the past. Maybe he means the _ **Device polling time interval** _: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/7/e7905bd0d20d027118c2424bb5826b7720807168.jpeg) As far as I know, this cannot be changed on the Homey. However, this should have nothing to do with the described issue. > [@Twan\_Janssen](#): > > but I cannot reset the walli switch to it’s default settings Because why not? Did you tried this one? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/7/b7809b63978da3005107560100fd5a05616a91ca.png) ---

Yes I did, when blinking dark blue, the switch reacts on nothing anymore, 3 times click just keeps blinking dark blue. ---

Yes, tried this but does not work. Fibaro support desk adviced to send it back. Was an internal firmware problem. ---
