If i purchase only wb5, do i not need a gateway to connect to alexa?

It doesn't need a gateway , it can connect to alexa directly . Can you send us your order ID ? support@btf-lighting.com

Can this controller run this led strips https://www.amazon.com/btf-lighting-similar-addressable-10pixels-flexible/dp/b0b9s3xfjb?ref_=ast_sto_dp&th=1

No，it cannot control it. You should use the SP617E controller to control the WS2814 RGBW LED strip

I cannot get this controller to display warm white, it only does cw. is it defective? (mine are 24vrgb-ww)

Can you contact us support@btf-lighting.com ? we need your order ID . If you just light up CW ,well you just light up mixed white(red+green+blue) not pure white , please set the controller indicator lamp to green , the green lamp is RGBW mode . And you light up note pure warm white . If you don't know , we can send you a video , please contact us .

Does it work together with a led driver controlled by a wall switch dimmer? i.e., dimmer switch to led driver to this controller?

This WB5 controller work with power supply . For example ,you light up some DC12V FCOB 2700K LED strips , you need a AC-DC DC12V5A 60W power supply . Connect the DC12V5A to this WB5 controller, the connect connect the FCOB LED strip . And then you can use the APP WIFI control this controller , Or use a RF panel remote to control .
