    Usually I don't prefer it because it is larger in size than the GS-WDS07 that I usually get from outside. It gives a signal that, for example, the door is open but it doesn't have a separate signal for closing. Also, out of the 5 that I bought, only 4 were working. The problematic one showed that it was working but the SONOFF® RF Bridge was not responding. So, I would only buy it again in absolute necessity.
