Automatic heater tool VW T5 Webasto

thingiverse

Automatic Preheater Tool: Is a simple tool to reactivate the preheater in vehicles like VW T5 to survive cold winter nights. The proof of concept will be an Arduino nano with a DHT11 and a small servo motor to push the button on the remote. Later, it's planned to install it on an WeMos to send data to a webservice and provide control over temperature settings. Basic Function: Is a simple tool that triggers the preheater button on the remote. The remote should be set to heat for 120 minutes for this concept. Housing: Designed to be 3D printed in materials like PLA, which takes about four hours to complete. Infill is used at twenty percent for all parts except the "Mid_ButtonTrigger" part, which should be printed solid (100%). Layer height doesn't really matter, but it will be printed with 300 micron. Support structure isn't necessary. Software: The software waits for 120 minutes and starts temperature checks every two minutes. As soon as the temperature drops below 19c, the remote button is pushed, and the loop starts again. Software: https://github.com/patrickstigler/automatic_preheater_tool
