Query and Surgestions for Yeelight Strip and colour bulb

Good afternoon, I am interested in purchasing some Yee light products but what I am interested in are the following

  1. Does it offer local control without the cloud for both google home and Alexa
  2. Doe your colour changing light bulbs/ strips offer different effect such as rainbow/strobe etc
  3. If not could you implement something like Air-cookie has done with WLED https://github.com/Aircoookie/WLED/wiki so you have a choice of colours and different effects?
