Quick start:

  • Step 1: flash the sketch with flash size include SPIFFS option.
  • Step 2: connect to device AP with name HVAC_XXXX (XXXX last 4 character MAC address)
  • Step 3: You should be automatically redirected to the web portal or go to 192.168.1.1
  • Step 4: set Wifi information, save & reboot. Hvac will fall back to AP mode if WiFi connection fails (AP password sets to default SSID name from step 2).
  • Step 5: find the device IP with last 4 character MAC address in your router
  • Step 6: (optional): Set MQTT credentials for use with Wirenboard
