# fc-enail

This project is inspired by the FC Community and a desire to have a better E-Nail product, with ease of use, advanced features, and wireless connectivity.

## Highlights

* Easy temperature adjustments with rotary dial
* Easy on/off of heater both on device and remotely
* Quick temps from mobile screen to go to a temperature with 1-click
* Save/Load profiles (PID settings and coil temperature offset) for different devices (can use auto-tune to generate)
* Run scripts for fancy up-temp procedures and the like
* Full mobile access including:
  * Remotely start, adjust temperatures, and monitor
  * Run scripts
  * Manage/create/edit scripts with the script editor (drag/drop GUI)
  * Manage profiles and launch auto-tune to generate
* Ability to connect device to WiFi network through device UI
* Automatic discovery of device on local networks, but ability to configure if not found or on different subnets

    enable_uart=1
    dtoverlay=disable-bt
    gpio=15,16,18,22=pu
    dtoverlay=audremap
    audio_pwm_mode=2
    hdmi_ignore_edid_audio=1
    
2. Create d:\wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
    update_config=1
    country=CA
    
    network={
     ssid="<SSID>"
     psk="<password>"
    }
    
3. Boot and run raspi-config
    a. Hostname: fcenail
    b. Set localization options: America/Toronto, en-US
    c. Enable SPI, I2C
    d. Disable serial console, enable serial

4. Install NodeJS

* Download unnofficial distribution for ARMv6
   * Create folder: /usr/local/lib/nodejs
   * Uncompress to /usr/local/lib/nodejs
   * Create symbolic link to /usr/local/lib/nodejs/current
   * Update profile/path (Add to /etc/profile)
     NODE_PATH=/usr/local/lib/nodejs/current
     PATH=$NODE_PATH/bin:$PATH
   * Run visudo and remove "secure_path"
   * Create symbolic links for node, npm, and npx:

     ssid=fcenail
     
     [wifi-security]
     key-mgmt=wpa-psk
     psk=1234567890
     
     [ipv4]

     dns-search=
     method=shared
     
     [ipv6]
     addr-gen-mode=stable-privacy
     dns-search=
     method=ignore
     ````

````
   sudo nmcli c add type wifi con-name wifi-wlan0 ifname wlan0 ssid <ssid> wifi-sec.key-mgmt wpa-psk wifi-sec.psk <password> 
   ````

Edit /etc/NetworkManager/NetworkManager.conf

`````
   [main]
   plugins=ifupdown,keyfile
   dhcp=internal
   
   [ifupdown]
   managed=true
   ````

Reboot and add hotspot
   
   nmcli c add type wifi ifname wlan0 con-name Hotspot autoconnect no ssid hotspot-ssid
       
   set priorities to 100 and 1 for wifi-wlan0 and Hotspot respectively.
   eg. sudo nmcli c mod wifi-wlan0 device.autoconnect-priority 100
