Unstable connection
Product ordered and received in August 2021. The configuration is very simple, but the connection is very unstable - the module configured as a "node" regularly loses its connection with the main box, or its configuration. The firmware is up to date, and the 2 boxes are in the same (large) room with no obstacles between them. I had to reconfigure the "node" box after 15 days of use, I had to reboot it yesterday, and today again. This hardware will be replaced as soon as possible - I strongly advise against it.
