I think there are several common themes that we keep seeing over and over again. One for Gen 1+2, which I use, and the second with Gen3, which I have not bought due to all of the issues.
- LIFX Bulbs like to be left alone.
Solutions users have found are either to put them on a separate access point and or SSID, or by putting them on their own VLAN.
For your test environment, I would recommend having as many “other” chatty devices on the network with the bulbs at the same time. And I would also use an Ixia Cloudstorm, or other device that simulates heavy network loads of disparate types. I would slam the bulbs with broadcast and multicast traffic from one of those tools and see how they respond. Determine if it is directly related to a quantifiable amount of broadcast traffic, and if there is a threshold after which the bulbs can no longer handle it. Could be horsepower or code that is causing the bulbs to overload.
- DHCP Problem with V3 bulbs.
I have not experienced this because I’m not buying gen3 until the folks on this forum start screaming HOORAY! However, I would build a VM host with every type of DHCP server you can get on there, and test 20 or more bulbs first without traffic, and then with traffic from your storm generator. You may have to byte the bullet and buy a bunch of chatty apple products using Bonjour, and that may do the trick as well. Next, I would purchase the routers that you can’t put on a VM, and that are specifically called out by the many helpful folks on this forum, and test each one of them in the same way. Which ones are working and which ones are not? And then the why? Why are some routers not having issues with DHCP, while others are?
With these two tests, and packet capture logs, you should be able see what situations cause the bulbs to flake, and send that on to your software developers so they can fix both the LAN protocol and the DHCP issues.
If your management gives you a hard time about the expenses of the recommendations above, gently let them know that LIFX will be out of business very soon if they choose to take the cheap and slow route - because the youtube reviews that in the beginning touted LIFX as the best smart bulbs on the market are quickly being eclipsed by reviews that tout the bulbs as a waste of money and completely unreliable. I say these things not because I am angry, but rather because I REALLY want you guys to succeed. Your bulbs are the best, and the final step is to get the connectivity problems worked out - before Hue and others catch up with the quality of your hardware. If the reputation of LIFX continues to be slammed, there will be no bringing the company back from that.
I hope this helps, although it may already be things you know.
