I barely have words that can adequately describe how infuriating this app/these bulbs have been. One of the worst apps I've EVER used. It's buggy, does not properly save settings inbetween turning the light off/on, is not userfriendly, you can't remove a device to start the process over when it inevitably gets messed up, etc. After a dozen or so attempts to get 2 bulbs to work in the same room, I am DONE with this product/app. Buyer beware!
