Hi @robertklep et al.
Here are my observations.
1. Hue lights connected to the Hue bridge.
Sensor - Homey - Bridge - Hue Light - Hue dimmer
a. Aqara sensor (connected to homey, naturally) triggers the flow with a delay, about 500 to 1500 ms. I’ve installed 2 motion sensors in the long bathroom, by the time I walk the first meter from the door the light triggers. Sometimes it triggers earlier, sometimes after 2 meters, which is a bit late, and I have to take care not to bump into things : )
b. the Hue dimmers connected to the Hue bridge trigger without the delay
This setup is kind of acceptable.
c. However, removing Hue lights from the homey Zigbee network means losing valuable routers, the Hue lights are actually being used at the moment as routers for other devices.
2. Hue lights connected to Homey directly
Sensor - Hue Lights - Homey - Hue Bridge – Hue dimmer
a. Aqara sensor triggers almost without a delay. Hard to say how much but if I am idle too long in the loo, I just need to flinch a shoulder and the light come back right away : ), ie under 300 ms I guess.
b. Hue Dimmers simply do not work with Homey directly any longer, therefore the only way is to connect them to the Hue bridge.
Triggering the flow from a Hue Dimmer via Bridge takes about 2-3 seconds, which is a very noticeable lag. You are not sure if the flow has broken again or it’s just a ‘normal’ delay.
This is not really practical.
To remedy 1.c. I could install another device as a router. People recommend Ikea Signal repeater, however, I read as well that Aqara sensors won’t work via Ikea routers!
This is where Homey is letting us down, because their claim of integrating different devices doesn’t not hold, if you can’t even route devices via a dedicated repeater because they are incompatible within the same Zigbee network. Since we can’t influence how devices are routed in Zigbee, the only option is not to use conflicting devices that limits my options severely.
