I have a Omega 2+ with the Power dock and an OLED expansion.
I'm trying to make a module to connect to the smart meter in my house in order to send HTTP queries to an influxDB in another device in my network.
The smart meter can be communicated using RS232 interface, although only RxD is available and it needs RTS to request the date. The connector in the meter is a RJ11.
I already have a USB to RJ11 cable with a FTDI chip specifically made for this purpose.
I was wondering if the Omega supports accessing the FTDI chip through USB. My original intention was to use the cu command but I didn't manage to get it through opkg.
Does anybody know an alternative for it?
Best,
Jacinto
