So, it`s still a work in progress, but getting there slowly.
New sensors have arrived, but I'm still waiting for the relays to arrive.
Latest status:
- Two new AM2301 / DHT22 sensors, for better accuracy, precision / repeatability, and resolution.
- Updated GUI to display last 24hr temperatures
- Better display on current air readings.
- Only pulling NTP once per hr
- Some error trapping routines for the wifi, preventing NTP request when wifi is unavailable, and also continously checking wifi status to periodically try to reconnect.
I still have left to:
- Implement control algorithms, which is harder than it looks; multiple input variables and priorities, but only controlling one output (fan speed).
- Maybe adding manual overrides
- Putting the hardware together
- Testing
