I just bought Daybetter LED strips, and they work perfectly fine with the remote and through the Tuya Smart app, but whenever I try to link my Tuya Smart account to my Google Home stuff, it keeps giving me the Error 404 message saying, "The requested URL was not found on this server." I have also tried the Smart Life app to the safe effect.
Thanks for reaching out. Please note that Daybetter LED strips are not officially supported by the Google Home/Nest devices. You might want to check if those lights are compatible to set up using a third-party app partnered by Google like Tuya Smart. You can also visit this link for the lists of applications that you can connect with your Google Home/Nest devices.

Hope this helps.
