Hi, Has anyone had any luck interfacing weewx (on a rpi) to this weather station (which is identical to the Bresser 6 in 1) and if so could you give me any pointers ? https://youshiko.co.uk/collections/digital-weather-stations/products/yc9388
My basic assumption is that this is a Fine Offset clone. The fundamental problem I'm having is with the USB interface $ lsusb -v -d 1941:8021 *Bus 001 Device 004: ID 1941:8021 Dream Link WH1080 Weather Station / USB Missile Launcher* *Device Descriptor:* * bLength 18* * bDescriptorType 1* * bcdUSB 2.00* * bDeviceClass 0 * * bDeviceSubClass 0 * * bDeviceProtocol 0 * * bMaxPacketSize0 64* * idVendor 0x1941 Dream Link* * idProduct 0x8021 WH1080 Weather Station / USB Missile Launcher* * bcdDevice 0.00* * iManufacturer 1 Silicon Laboratories Inc.* * iProduct 2 CCLEL C8488* * iSerial 3 CCLEL c8488* * bNumConfigurations 1* * Configuration Descriptor:* * bLength 9* * bDescriptorType 2* * wTotalLength 0x0022* * bNumInterfaces 1* * bConfigurationValue 1* * iConfiguration 0 * * bmAttributes 0xc0* * Self Powered* * MaxPower 100mA* * Interface Descriptor:* * bLength 9* * bDescriptorType 4* * bInterfaceNumber 0* * bAlternateSetting 0* * bNumEndpoints 1* * bInterfaceClass 3 Human Interface Device* * bInterfaceSubClass 0 * * bInterfaceProtocol 1 Keyboard* * iInterface 0 * * HID Device Descriptor:* * bLength 9* * bDescriptorType 33* * bcdHID 1.11* * bCountryCode 0 Not supported* * bNumDescriptors 1* * bDescriptorType 34 Report* * wDescriptorLength 36* * Report Descriptor: (length is 36)* * Item(Global): Usage Page, data= [ 0x00 0xff ] 65280* * (null)* * Item(Local ): Usage, data= [ 0x01 ] 1* * (null)* * Item(Main ): Collection, data= [ 0x01 ] 1* * Application* * Item(Local ): Usage Minimum, data= [ 0x01 ] 1* * (null)* * Item(Local ): Usage Maximum, data= [ 0x08 ] 8* * (null)* * Item(Global): Logical Minimum, data= [ 0x00 ] 0* * Item(Global): Logical Maximum, data= [ 0xff ] 255* * Item(Global): Report Count, data= [ 0x40 ] 64* * Item(Global): Report Size, data= [ 0x08 ] 8* * Item(Main ): Input, data= [ 0x02 ] 2* * Data Variable Absolute No_Wrap Linear* * Preferred_State No_Null_Position Non_Volatile Bitfield* * Item(Local ): Usage Minimum, data= [ 0x01 ] 1* * (null)* * Item(Local ): Usage Maximum, data= [ 0x08 ] 8* * (null)* * Item(Global): Logical Minimum, data= [ 0x00 ] 0* * Item(Global): Logical Maximum, data= [ 0xff ] 255* * Item(Global): Report Count, data= [ 0x08 ] 8* * Item(Global): Report Size, data= [ 0x08 ] 8* * Item(Main ): Output, data= [ 0x02 ] 2* * Data Variable Absolute No_Wrap Linear* * Preferred_State No_Null_Position Non_Volatile Bitfield* * Item(Main ): End Collection, data=none* * Endpoint Descriptor:* * bLength 7* * bDescriptorType 5* * bEndpointAddress 0x81 EP 1 IN* * bmAttributes 3* * Transfer Type Interrupt* * Synch Type None* * Usage Type Data* * wMaxPacketSize 0x0040 1x 64 bytes* * bInterval 1* *can't get device qualifier: Resource temporarily unavailable* *can't get debug descriptor: Resource temporarily unavailable* *Device Status: 0x0001* * Self Powered* Running wee_ device works, but the values returned are all defaults not what the console is displaying. $ sudo bin/wee_device --info *Using configuration file /home/weewx/weewx.conf* *Using FineOffsetUSB driver version 1.20 (weewx.drivers.fousb)* *Querying the station...* *Fine Offset station settings:* * local time: 2020.01.03 17:47:03 GMT* * polling mode: PERIODIC* * abs_pressure: 0* * current_pos: 0* * data_changed: 0* * data_count: 0* * date_time: 2000-00-00 00:00* * hum_in_offset: 0* * hum_out_offset: 0* * id: 0* * lux_wm2_coeff: 0* * magic_1: 0xfa* * magic_2: 0x 3* * model: 0* * rain_coef: 0* * read_period: 0* * rel_pressure: 101.8* * temp_in_offset: 0* * temp_out_offset: 0* * timezone: 0* * unknown_01: 0* * unknown_18: 3* * version: 0* * wind_coef: 0* * wind_mult: 0* * max.abs_pressure.date: 2000-00-00 00:00* * max.abs_pressure.val: 0* * max.dewpoint.date: 2000-160-03 00:00* * max.dewpoint.val: 0* ....

I should say I was using the latest stable version on a rpi4 but wee_device crashes with this on the first usb block read (errno 75, Overflow). I am now using 4.0.0b6 on an rpi2 which at least doesn't crash. I have attached a laptop running windows with the manufacturers software - this works perfectly (but the software is very limited) so at least I know the weather station is fully functional Thanks Bob -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
