Amazfit Watch faces

Can anyone share on how to add weather into the screen of Mi Band 4?

I have looked at this, just recently. I have been able to determine that the MI4 band has 30 weather icons 4 more that other watches do not seem to have. For example there are three night weather icons used by the MI4 that show from time to time in the weather menu area of the watch. Even though I know the complete icon set this is not enough to make weather work in the MI4 as I believe it has not been implemented fully in the firmware. For now it is something that cannot be consistently used. Some users have, or seem to have success with there WF's but for now I for one will but it on the back burner and wait on future firmware updates to see if it becomes routinely available. You can look at other watch faces that appear to display weather data to see how JSON code is, or might be used, but this is based on other watch faces like cor and bip. I think it may be similar for MI4 bands but is generally unsuccessful in use.

Thanks for the info... now i understand why there is no option for weather in WF builder. Maybe will have it in the future in more updated firmware
