Is Ring Hub defective

Don’t know if the Hub is the same thing as a Base Station.I’m going to post a question concerning my Mailbox sensor because, initially, it is a separate device, but I’ll encourage readers to check that post before answering here.I’ve posted here about a few devices that seem to be malfunctioning recently (check out my hx). I’m now uncertain whether all these devices are malfunctioning within few months or if the Hub is the problem and problems with my devices are just symptoms.I know I’m asking for a little more time than usual because of my previous posts and my following post on the Mailbox Sensor, but I want to know if I have a few devices misbehaving or if replacing on (the Hub) is the solution.
