wee_device cannot be used with acurite stations. this is because the acurite stations cannot be controlled from software; the only way to change the console parameters is to push buttons on the console the early model raspberry pi have usb power issues - they do not work reliably with some weather stations, including acurite, fine offset, and te923. using a powered hub usually eliminates the usb power issues. the pi2 and pi3 seem to have fewer usb issues. however, there are also kernel-related usb issues on the rpi (and also on other arm-based architectures). we have seen cases where one kernel version works fine on an rpi, but upgrading to a later kernel causes problems. there are also issues with different libusb versions (and to a lesser extent, different pyusb versions). for example, i have had problems with libusb 1.0.11 that went away when i upgraded to libusb 1.0.20. i'm sorry i cannot provide specific kernel or operating system versions to back this up or steer you in the right direction m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
