I have a couple of these units weather station base units with USB.
The older one has a serial-USB smd chip on-board and a relay. The newer one has the chip built into the board and covered with a black blob. The older one appears in with $ lsusb as:
Bus 004 Device 002: ID 1941:8021 Dream Link WH1080 Weather Station / USB Missile Launcher
and used to show up with $ ls /dev as a hidraw device.
That was until the last “apt-get upgrade”. Now it’s still there with lsusb but gone from /dev
How to get it back:
