Hi,
I have a sonoff door sensor model SNZB-04 and it seems it can tell if it was tampered - it sends its boolean value. I always receive the value as “false”.
How can I test it? How can I “tamper it” in order to get that value as “true”?
The device doesn’t seem to have any other switch, so I wonder if this field is useless or if it has any use…
Any idea?
Thanks
