I was reading the changelog for the Home Assistant SLZB Add-on and saw they added support for the SLZB Ultima. I looked it up on Aliexpress out of curiosity, expecting it to be their most expensive offering since it has 4 antennas for Z-Wave, Zigbee, Thread, and 4G/LTE. Also RGB (eyeroll). But its price is similar to other SLZB offerings. I'm suspicious since it seems too good to be true. Is the price low because there was no support previously or are there problems with the device?
