So I have multiple Hue bridges in this house. Each bridge has a room and a lot of lights connected to it. For simplicity let’s say I have one Bedroom and one LivingRoom bridge.
When I connect the first bridge (let’s say the Bedroom bridge at 192.168.1.9) to HA using the configurator and simply clicking the button on the bridge itself, everything works instantly. I can call scenes with hue.hue_activate_scene, control all the lights individually, all good.
Then I connect the LivingRoom bridge (192.168.1.10). Now I see all the lights, I can control all of them and turn all of them on or off. All good still. In fact, I can call scenes with hue.hue_activate_scene just like the Bedroom one!
But after this pairing, I try to use hue.hue_activate_scene again on the Bedroom… and nothing. I try other scene names to make sure I’m not misspelling anything, and still nothing. All spelling is correct, so I check the logs and see this:
Unable to find group Bedroom
9:28 PM components/hue/bridge.py (WARNING)
If I then remove the LivingRoom bridge from HA, reconnect it, and call the scene, it will work again. But then, I have the same exact problem with the other bridge! It seems like I can only call scenes on the last bridge I have connected. I cannot call scenes on multiple bridges. The documentation on the website mentions nothing about this and I cannot find anything regarding this issue online. Every time I add a new Hue bridge, I am only able to change scenes using hue.hue_activate_scene on the last bridge I connected. All the other bridges I connected to HA before that will still be available in the UI switches, I am still able to turn lights on and off, just not activate Hue scenes. I always get the error above in the HA logs.
HA should be able to select any hue scene using the hue.hue_activate_scene, as long as the group and scene names are correct. Would be a great fix for people who have more than 1 hue bridge.
