Problem: the fan doesn't vary with temp or humidity

Problem: the fan might turn off if there's a problem elsewhere

Here's what I did:

  • Added watchdog functionality that ensures the fan continues running even if the main control system stops sending commands
  • Added a 10-second timeout to detect control failures
  • Automatic fan control based on user-defined setpoints (Home Assistant and MQTT) to attempt to maintain set temp or humidity

Might be useful. Enjoy!
