Supported Devices

It should work with most esp32 controllers, but the easiest way is to use an esp board which already has 4 relays on it.

How to use (binary with loader)

Its recomended to flash with loader, that way you can always go into recovery mode and flash new firmwares over wifi.

Wifi

To configure wifi either do idf.py menuconfig, and configure wifi SSID and password, or let esp-brew-engine start an access point wich you can connect to and configure wifi in the webinterface.

Be sure to at least change te password!, but it is also recommended to swith to station mode instead of ap!

Default Wifi settings are: SSID: EspBrewEngine Password: EspBrewEngine123

Connecting with Browser

Just open your browser and enter http://BrewEngine, or if still in access point mode http://192.168.4.1

Hostname can also be changed via menuconfig.

*Dns does not work when in access point mode, esp-idf doesn't have a dns server atm.

Debug

idf.py monitor 

To quit Ctrl-T Ctrl-X.
