Thank you for the feedback!
I have actually only 2 Tuya mmWave radars and I run these on two different hubs - one C-7 and one C-8. But as I know, @jw970065 is running much more on a single C-7 hub.
@jw970065 have you noticed any issues / slowdowns when using several (how many actually?) Tuya radars on one single hub?
