My system uses several LIFX Mini (C and W) bulbs. These bulbs are all V3.60 firmware. All of these work properly with the PG3 LIFX NS.
I tried to add several new bulbs. These have v3.90 firmware. These new bulbs add properly to the network and can be properly controlled by the LIFX cell phone app.
The PG3 LIFX NS discovers the bulbs and adds them to the IOP Admin console device tree. On the Admin Console page for these bulbs, all are listed as offline and cannot be controlled via PG3
After more tinkering, I discovered that the problem with using v3.9 LiFX bulbs is not PG3. The problem is with using a devlist.yml file. With previous revisions of bulb FW, the bulb MAC that the router associates with an IP and the bulb SN that the PG3 devlist contains were the same. Now, with firmware 3.9, the MAC address is different from the bulb SN.
Here is how to use LiFX bulbs and a devlist if you have any bulbs with firmware version 3.90:
1. Add LiFX bulbs to your WIFI network.
