Develop an application to optimize energy for controlling dew into room

[Trebly]

Hi,

I wish to develop an application or use an existing one to perform these functions :

• Open windows and start air extraction when the external dew point is less than the internal dew point - let enter air more dry than the inside air. But stop it if the temperature become inferior or superior to defined values (manage air circulation from exterior and extract if humidity can be reduced by this way)

• If the internal relative humidity is greater than a defined value (case 75% particularly) start a humidity extractor

• send data and events warnings by http communications.

I search for information on how to use Arduino Nano Dew Controller Pro (DIY) to perform these function or base to develop enhancements.
Note : I have not found an application which are using the comparison of dew points external and internal to decide to start vs. stop an artificial and/ or natural air circulation form exterior to interior and the extraction of humid air only if the external is less humid than the internal...

Best regards

Trebly

Hi Trebly
I do not think that the myDewControllerPro wil be of much help.

To measure both internal and external dew points will reqire two temperature/humidity sensors, located one outside and one inside.
To send http would require somethng like an ESP32 or ESP8266 chip
The logic seems straightforward.
