These work really well
Bought 2 to monitor a leak in the roof, which they did well and averted disaster. Bought 4 more for around water tank, behind dishwasher, washing machine etc.

very expensive device is no different from cheap analogues
it is impossible to use with Alexa, it does not work with Alexa as indicated in the description. I asked the support group for help, but they never answered to me. This service is just for show, in fact it is non-working. You won't hear any signal, just get a notification on your phone. A dubious and very expensive device is no different from cheap analogues.

No network connectivity
Highly anticipated purchase, unfortunately it did not live up to the product marketing. Tried over two days to get the Hub to work on Ethernet and WiFi but would constantly dropout. Contacted Tech Support, who to be fair did what they could but in the end had to return the kit for refund
