Back during the Pandemic, my Mate3 stopped displaying information. It worked if I plugged it into any of my Outback devices (two Radians and four FM80's) one by one, just not with the hub. Due to the electronics shortages, replacements did not have the 'Ethernet' functional, so I waited. I haven't changed any of my settings in what seems like at least 5 years. Everything ran just fine, just no monitoring via the internet.
Earlier this month, I finally saw that the 'non functional' eithernet port note was removed, so I bought a replacement Mate3s and Hub.
What does this sticker mean? I don't want to open up the sealed documentation if this is how 'non functional Ethernet' is communicated. If that's the case, I'll send it back.
