I havent had very good luck with the eg4 wifi dongles. I have to reset them every once in awhile which is annoying. also one of mine seems to only be able to update every couple of minutes which was causing silly readings in solar assistant.
I thought i should be able to hook directly to rs485 via usb converter using the HDMI pins.
a couple bucks on amazon for the hdmi repair pieces and the usb/rs485 converters and i was off to the races.
I ran the wires 50 feet (twisted pair) to the raspberry pi in the server closet. It works great. I get readings every 10 seconds flawlessly.
