I just want to understand, every device will need to connect through edge drivers now??
i have ikea zigbee bulbs, aeotec sensors etc. that connect directly to the hub without the need of a device handler. i still need to reconnect the products in order to make it connect through edge driver??
Any device that is directly connected to the hub would require a device handler or Edge Driver. Groovy Device Handlers will be phased out in a few weeks. You do not need to do anything on your part (unless you want to) as St will migrate devices over to Edge Drivers automatically.
Devices that connect to ST by cloud-to-cloud, you do not need to do anything with those.
