The Green Bean Maker Module by FirstBuild will allow a PC or Raspberry Pi to directly interface and control some higher-end GE appliances. Could be a good way to monitor the temperature of a refrigerator or set your dryer to run an extra 20 minutes. Read all about it here.
Sounds very interesting. The module is just a USB adapter to the internal bus and it’s cheap - $20. SDK is on GitHub: https://github.com/GEMakers. From the API, it looks like you can get every bit of information about appliance. Would be great integrating it with ST.
