Dear@416to305, regarding the Hue lamps happy that the EA5 fixed the apparent problem, although for the future readers I might have some hints:
it is better to use a Philips Hue scene inside the Hue and trigger that from outside, this way all the Hue lamps are in sync (this can be done with this driver https://www.unilogiq.com/en/control4-drivers)
The farther the lamps away from the Hue Gateway the longer the link (it's a mesh network), the higher the probability to receive all commands, thus make sure that the Wifi and Hue frequencies are set properly for coexistence (https://www.metageek.com/training/resources/zigbee-wifi-coexistence/).
Limit the number of devices per Hue Gateway to 50 (the gateway is not a race-car ) otherwise commands might get dropped
Limit the number of pulls from the Hue Gateway by different apps so that the Hue gateway is not under high load
Make sure the Hue lights are always powered
