Setup and configuration of my working DF Robot RS485 7-in-1 Weather Station Sensor SEN0657 and Waveshare RS485 to ETH integration (C) 30303
My first post, hoping to save others time and effort.
Both were supplied with 12v DC. The waveshare could not power the weather station from the output terminals on the RS485 connection side, I connected to the input instead. This may be something to watch out for on this device.
Waveshare Web Configuration. I had issues using DHCP and recommend static only

Some scales seem off and may not be right, windspeed seems low at scale of 1.
Some data is not available for the 7in1 and/or 9in1, you can delete as needed
As other posts have covered, if waveshare is TCP to RTU then home assistant yaml should be tcp only.
