Yeelight Smart LED Ceiling Lamp White

Nice lamp. I have white, blue and yellow. Light temperature can be set only in case of white one. That was not clear from description. I am satisfied with all lamps. Anyway I have 2 proposals for enhancements. 1. Could be possible to disable/reduce wifi connectivity. E.g. connectivity is available only for few minutes to allow fw upgrade. 2. Controller coud be mountable to a wall. Like IKEA TRÅDFRI. https://www.ikea.com/sk/sk/manuals/tradfri-dialkove-ovladanie__AA-1895963-1_pub.pdf
