Good evening, I have reduced the kaku lamps in my living room and go slowly towards zigbee. When I still had a lot of kaku I had made a device “all lamps” that switched everything. And then added a device for each lamp. Now I have zigbee and I don’t think they listen to multiple signals. I don’t know if it’s because of the speed of homey bridge, or if it’s also the same with the pro. But when I press my lighting on button it takes a while before everything is on one after the other. 6 lamps x 1 sec per lamp. I like that… But my girlfriend is going crazy and immediately presses all the buttons to “solve it”. She clearly wants it faster. Is this a homey bridge thing? Can it be solved with your cleverness? Thanks in advance! ---

It sounds like a Bridge thing; with Homey Pro, you end up with a random half of your light not being switched on or off (in other words: flows that control multiple devices tend to not work very well on Homey). There’s a basic Zigbee feature called “grouping” where you can make devices part of a group, and send one Zigbee command to that group to turn all lights in the group on/off. Sadly, Homey (Bridge ór Pro) doesn’t support this feature. ---

It’s a pity a 2021 Homey Bridge device can’t turn on a bunch of zigbee lights at once… (I understood it uses the same hardware as a 201x Homey ‘Pro’) **But…** A workaround can be: - Flow A If… Switch A is turned on Then… Turn on Lamp A And… Start flow B - Flow B If… this flow was started Then… Turn on Lamp B And… Start flow C - Flow C If… this flow was started Then… Turn on Lamp C And… Start flow D A bunch of extra work maybe, but it _could_ (not tested) make the lights to be switched on, one right after the other, instead of one per sec
