Hi,
I have just bought a couple of shelly D/W 2. One of them is struggling in coupling with my home network. The first time I coupled it no problem, but then after one day, I needed to disconnect it because of a false open door alarm. Then I unplugged the batteries and plug them back again but nothing, it just slow flashing the red led but I can't add anymore it to my home network.
How can I reset it or solve the problem? Thank you
