I setup my pH probe today and am having a problem. While it's running it randomly gives an error:
ph subsystem: Failed read probe:Sump pHError:strconv.ParseFloat: parsing "7.647\x00\x00\x00\x00\x00\x00\x00\x80\x00\x00\x00\x00\x80\x00\x00\x00\x00\x00\x00\x00\x80": invalid syntax
It then ceases to work. I can reboot the pi and it will sometimes start to work, but other times it won't. How can I figure out what's causing this and fix it?
Also, under the pH there is an entry called "Chart Unit". I've left this blank and it didn't complain, but I have no clue what that would be. I tried putting things in it and couldn't tell that it did anything at all.
