Perhaps you should evaluate it. It’s the only device I found that allows to connect a bunch of wired zones to M1. So in a set up where you have a bunch of wired zones going to a different location, like a second apartment, there aren’t that many options. Going full wireless not only costs several times the price, but also, might not fit well in place of existing sensors.
And it’s been working perfectly for me except this optional loop 4 issue.
