When I start a flow that sets 50 KNX dimmers to a certain dim level always about 5-10 dimmers do not react. The dimmers involved seem to have been chosen randomly. I need to start the flow once or twice again to have all lights turned on. Now I’m sure that Homey sends them all out. All lighting ico…

Homey has troubles with commanding more than X devices in one go, at least with zigbee. Maybe setting 50 dimmers at once is too much, either for Homey or the KNX GW. You can try to delay every group of 5 action cards f.i. Like THEN… set dimmer 1 set dimmer 2 set dimmer 3 set dimmer 4 set di…

[image] Beukenoot: Now I’m sure that Homey sends them all out. All lighting icons light up in the app. When looking in the bus monitor within ETS however, the lights that are not turned on are missing! So how do you conclude that Homey sends them all out? It seems to me that Homey thinks it s…

Wow, I didn’t know that. This affects the robustness of the app so much and it seems so unlikely to me that it would be hard to resolve. Maybe just a general setting of a delay between commands or something like that might help.

I don’t think Athom has even acknowledged that this problem exists, even though a lot of Homey users run into it. The issues started with Homey firmware v2, where Athom rewrote the flow handling. That was 3 or so years ago. Given that the issue still exists, I have to conclude that Athom is unable t…

Two more workarounds: [image] Switching on zigbee lamps (serie of 10) slow all of a sudden A way to avoid delays of whole seconds is to create 3 flows which control 1/3 of the lights each. Flow 1 switches on say 3 lights and starts flow 2 Flow 2 switches on another set of 3 lights and starts f…

Thanks for the tip! Using the app with a 100ms delay seems to be a work around for a Homey bug.

Does using 3 separate flows actually work around the problem? Because you’re basically starting 3 flows within milliseconds of each other, and each flow is switching 3 lights, so you still have 9 or 10 lights being commanded at almost the same time.

I didn’t try that but if there is a delay of x msecs before a flow is started, this might very well work. For me though, this would be too much work and my flows would become too complex and hard to maintain.
