I've published a project "talk to Arduino" it controls outputs of Arduino connected via OTG. Some Arduino Uno or Nano may not work well depending on the integral USB to Serial.
Please comment how it works.
I'll have a look.
It is a very good project
If I had the same problem I would have put another thermocouple in series to the one there, 60mV is better than 30mV. Maybe the old gas valve needs more juice. Besides if your wife will find out that you received an email from a thermocouple you will be in big troubles.
