WL-19DWZ Wrong message

[albertinizao]

What happened?

After the 1.41.0, the contact sensor now detected as WL-19DWZ (previous version was detected as SNZB-04) works wrong.

Arbitrarily these devices are sending me incorrect messages with “contact=true” without the actual state of the device having changed. In this case, at 23:10:03 the device did not change his real status, without any movement, but sent these messages.

What did you expect to happen?

The WL-19DWZ should not send any message with "contact=true" when the door is open

How to reproduce it (minimal and precise)

Version 1.41.0. Put a device WL-19DWZ close and then open it. Review the status is now opened (concact=false). Wait until a message with contact=true is sent, . Sometimes it happens a few minutes later, sometimes a hour later.

I got the same problem with any of these devices: they suddenly set 'contact' to 'true' - after long or short duration of time

Should be fixed in the latest dev branch
