Hi I use a small pc to control my heating system plus recording and analysing solar energy and usage data. I collect this data from an EmonTX device which has a TTL output.
I use a TTL to usb converter and read the data into the PC Virtual serial Port.
This has been working fine for ten years now But I need to move the PC away from the EmonTx device and I can’t just use an extended USB cable as it’s too awkward, so I want to
Covert TTL to ethernet or usb to ethernet.
I have played around with a TTL to Ethernet converter but as the software provided was in Chinese I didn’t get anywhere. I need something that will provide a webpage on the device that my software can scrape.
If any one has done something similar I would be grateful for some advice.
I have not done anything similar but found this interesting: https://emoncms.org/
Seems that the V4 controller can post data to a web server and that would give you a simple remote connection to analyze the data.
Depending on how far you have to go, you could add a differential line driver and receiver to a CAT5 cable and extend the TTL signal. Then put the USB converter at the other end?
Thanks for you suggestions
I have an EmonTX V3 and it has no working connection other than the TTL output unfortunately.
Although I have cat 5 cable to where i want to put my PC it’s used for the Network so no actual spare cat 5 to that point.
ah, so the small PC is running a Microsoft OS. There are a handful of commercial USB-to-IP software and hardware solutions for Windows. The hardware versions seem to be in the $50-$200 range and software in the low end of that. A quick search turned up an open source implementation for Windows but I have no idea if it works or how well it works. Linux-only PCs here.
