i have a panel multimeter that i use for my whole house that has RS485, Modbus RTU comunication.
I know what registers to read in order to get currents, voltages, power factor etc
How can i use this and get the data to a PC, i have an arduino but i don't know how to get this started
I've tried using a RS485->Ethernet converter and then tried to send comunicate with the device via TCP-IP but it's rather difficult (this method would be the best, netowk conectivity ensures i can have the data parsed at my server)
I have sucessfuly conected an RS232 device -> Ethernet convertor -> PC, but in this case the device (a PBX) sends the data clearly in ASCII and it i manage it easily with a small Python program that reads the data and then puts it in a mysql DB
How would you reccomand to connect and program sometging like this:
Meter with RS485, Modbus RTU -> RS485 to Ethernet convertor -> PC with python script getting all the data (it's gonna have to be a lot of HEX coding that i would need a getting started point :D )
