Yup, 99% of the lights are Hue, on a hub, one upstairs one for downstairs.
Motions sensors not involved in hue lighting are on zigbee2MQTT, all the motion sensors related to Hue lights remain on hue hubs.
I managed to get a whole pile of hue external Motion sensors for £15 each, so have loads and use them as outdoor triggers, in fridges, freezers whole house battery cab8net, sheds, drive etc.
This way if, and I have the Mac mini running zigbee2MQTT, MQTT Broker, node Red, running on a 20kWh failover battery.
NB, the battery charges at night during cheap rate, and discharges during day at peak. I have all critical equipment on the failover if the grid goes down.
