Hi, I am using about 20 KaKu switches (awst9000) together with some IKEA Tradfri lightbulbs (±20) and KaKu build in dimmers (±20) (for example ACM-250-LD and AWMD-250) all working on Zigbee as far as i know. I am running homey version 7.1.1 and updating automaticaly. I hoped that the communication between these devices would be fast because I kept it by only 2 different brands but the average reaction time is around 2 seconds and some times the lights or dimmers don’t even respond at all. When I use the flows in my Homey app, they always respond and the response time is a bit better. I am not using any bridges because I was told that this isn’t required and that Homey is the bridge in this case. I also need to say that there is no AWST-9000 in the KaKu app so I have selected the AWST-8802 instead. This also results in the mix-up between the left and right buttons. My house has 3 levels with each around 90m² and my homey is postioned at the first floor. I am using Ubiquity for my wifi network and have a good wifi coverage on each floor. If you have any suggestions, tips or questions to improve my set up, please let me know. ---

I guess you searched the community and didn’t find much issue’s for [kika](https://www.kika.nl/) > [@Gijs\_van\_Hoek](#): > > AWMD-250) all working on Zigbee as far as i know [https://klikaanklikuit.nl/product/inbouw-leddimmer/](https://klikaanklikuit.nl/product/inbouw-leddimmer/) Productlijn [Start Line (433MHz)](https://klikaanklikuit.nl/productlijn/43392-mhz-1-weg-communicatie/) Same for awst … And I really hope you don’t put trådfri lights behind KAKU dimers… ---

Sorry, i meant KaKu and off course i don’t use smart bulbs behind smart dimmers. I only use the smart dimmers on led lights and drivers to make them smart. ---

Are you saying that the dimmers and switches aren’t using Zigbee but a 433mhz signal? ---

Yes, that’s what he’s saying. Also what Klikaanklikuit are saying. So it’s a bit of a mystery when you say that “_When I use the flows in my Homey app, they always respond and the response time is a bit better_”. Because how can you _not_ use flows to control the Zigbee lights from 433Mhz remotes? ---

Thanks. I meant that when I directly start/test a flow in the Homey app instead of pressing the physical switch on my wall. ---

Kaku with zigbee is “[Trust Smart Home KaKu](https://homey.app/en-gb/app/nl.klikaanklikuit.zigbee/Trust-Smart-Home/)” and the modelnames start with a `Z`. I also use 433MHz KaKu devices, and starting a flow with a wall push switch takes around 2secs
