I am running an google mesh network over a big place, openhab2 on a pi, msqtt, some sonoff/tasmota switches, NodeMCU, and a hue bridge with lights. All good so far.
Now, I am trying to add some lights at the far end of the network, where the wifi down there meshes with a google wifi (nest), which in turn relays to the google hub, where the hue bridge is cabled (as is the pi). Am I correct in that the lights have to be in direct wifi range of the hue bridge (not via the intermediate google wifi point)? If so, I am thinking of dumping the hue bridge and going down the zigbee route - I need to control those lights way out there. As I explore the zigbee route it seems it needs a bit of kit, a USB dongle? Thoughts? Or should I just dump the separate zigbee/hue control, and use NodeMCUs and Sonoff/Tasmotas instead?
