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.
