These are only $69.95 for a 4 pack with the Hub at Best Buy.
Just purchased a 4 pack of Sengled Color Bulbs with Hub which you can use to update firmware.
I don’t use it with HA because I have a HUSBZB-1 Zigbee stick and they pair perfect and allow you
to control color from HA.
When you pull them out of the box from the on position turn off and on fast 10 times and then they
will flash 4 times and change colors that is how you know they are in pairing mode.
Then go into HA and do add new device should pick up the 1st time.
Not sure how long they will be on sale.
