Not really, because he states it also happens with the Hue Zigbee app, in which case there’s no Hue bridge/API at all.
The problem is two-fold:
- Homey has problems executing multiple action cards at once, especially when those cards involve switching Zigbee or Z-Wave devices (that’s why you’ll see people using workarounds like adding delays)
- Homey doesn’t support Zigbee grouping, where you can add multiple Zigbee devices to a single Zigbee group (which allows you to switch all of those devices using a single Zigbee command).
Because the Hue bridge does support grouping, it works when you switch an entire group using the Hue bridge app.
