2. You are on the right track for figuring out which serial port
your Meteo-pi is using. However, by using 'grep serial' you are
excluding usb converter messages. Instead, try

dmesg | grep 'tty


$ dmesg | grep 'tty'
[    0.000000] Kernel command line: coherent_pool=1M 8250.nr_uarts=1
bcm2708_fb.fbwidth=720 bcm2708_fb.fbheight=480 bcm2708_fb.fbswap=1

[    0.931796] 3f201000.serial: ttyAMA0 at MMIO 0x3f201000 (irq = 81,
base_baud = 0) is a PL011 rev2
[    0.939379] 3f215040.serial: ttyS0 at MMIO 0x0 (irq = 53, base_baud =
50000000) is a 16550


3. Assuming you have the right port, your Meteo-pi is not acting like
a Davis clone.


The seller answered and sent me a manual for … Cumulus. I will try
anyway tomorrow.
