Would anyone have any recommendations for a modbus newbie on getting a pi to talk to a communicating sensor?
2 options
Option 1, $10: https://www.amazon.com/Serial-Converter-Adapter-interface-FT232RL/dp/B01MYSQLF0
And these steps https://medium.com/@boonsanti/raspberry-pi-3-model-b-modbus-rs-485-to-modbus-tcp-ip-gateway-9ed14ce2c08e
OR this pihat option 2, $40: https://www.instructables.com/id/How-to-Use-Modbus-With-Raspberry-Pi/
Option 2 seems like it even has a package to install in the directions called minimal modbus. Any idea if that would be utilized on both options? If one option seems easier for a beginner that's what I'll choose!
Temp and humidity sensor test trial if I can get it to work I'm hoping for a modbus electrical sub meter:)

Thanks for any help/tips!
