Hardly used and no visible scratches. Works perfectly fine but I installed home assistant on a different machine so am selling this one. Has Zigbee/Thread/Matter 2.4ghz antenna built in. I will include a z-wave GPIO module from Zooz with the latest 800 series connectivity. The PI CM4 has 2gb RAM, WIFI connectivity, Bluetooth, and no eMMC. The 256gb SSD is included since the CM4 has no eMMC. You can turn indicator lights off in settings. I will have HAOS pre installed. To buy all parts new I spent $270. I will add photos in a few days or you can ask for some.
