My test unit had a firmware update and was pretty reliable. Pairing still needed a SSID without certain characters but could take complex enough passwords.
Been solid until today when I killed to power to do some work, once it came back on the device wouldnt connect to the wireless again.
Probably going to have to reset it and test again, but for a security device it might not be good enough
A device that requires this and that and that and a blood sample isn't good enough ever.
Not even for a security device.
WIFI is WIFI if you aren't going to follow the right standards then I won't use your product.
