8 faulty modules XY-BJ  from store  Fancys Module Mall with Aliexpress

Below are the errors in the software of the XY-BJ module:

1. As you know, in the month of December of any year there are 31 days. You cannot set this date in this module. Only from 1 to 30. So in real time this module will not work correctly. Please watch the video below:

2. Mode introduction P-2: "set the day, to the OPE time point when the relay closed or output pulse, to the CLE time point when the relay disconnect / or output pulse". You can not set the day, this parameter is simply not there. Mode P-2 is equal to Mode P-1. Mode P-1 also not working cannot set the 31 day of the month. Only from 1 to 30.

3. Mode introduction P-3: "set the date of the month, to the OPE time point when the relay closed or output pulse, to the CLE time point when the relay is off or output pulse". In this mode, you cannot set the 31 day of the month. Only from 1 to 30. Thus, in real time, this module will not work correctly. Please watch the video below:

4. Mode introduction P-4: "Set the date 1 to date 2, start every day at the OPE time point, end to the CLE time point, relay action or output pulse". In this mode, you cannot set the 31 day of the month. Only from 1 to 30. Thus, in real time, this module will not work correctly. Please watch the video below:

5. Mode introduction P-5: "As with P-4, only the month can not be set"

The error is exactly the same as in P-4 mode. That is, in this mode, you cannot set the 31 day of the month. Only from 1 to 30. Therefore, in real time, this module will not work correctly. Please watch the video below:

And in conclusion, a surprise. These 2 modules do not work. I’ll Blacklist this store and I will never buy anything from it. And in conclusion, this module is not yet ready for sale - it is a toy.
