I’m using the card " zet…aan" for … I used “alle lampen”
but if I trekker the flow not all my lamps are turned on only the lamps in the “woonkamer(living room)”
After I added an extra card, all the lights in the house turn on
Homey cannot usually turn on/off a lot of devices at the same time reliably. Even if you add an extra card it can still have issues where random lights don’t turn on/off when they are supposed to.
A lot of solutions exist where lights are switched with delays.
There is a “Turn on” card for every zone.
If you want to change replace the card with the card from another zone.
(This issue pops up often… It’s quite unbelievable Athom still hasn’t deprecated those cards, or better, fix them by sending device commands shortly after eachother instead of all at once.
But, maybe their implementation of grouped devices ends this design flaw 
)
I question if the Problem the TS address’s if the issue about switching multiple devices at once or the fact that the card is tied to a zone. You can only change the device type not the zone.
If you want another zone you have to replace the card .
