For incomplete PCB, need

1. U10, U12, U15 soldered from side of PCB - order
   
2. soldered U14 order
   
3. rev 0.4 issue - change resistors to 100R or soldered over existing
4. soldered P1 order
   
5. soldered P2 order
   
6. soldered EXT1, EXT2 order
   
7. connect ESP32-POE order
   
8. POE injector order
   
   1. Warning: do not connect POE and USB cable in same time!
      

After PCB assembly

1. Test if works
   1. Upload firmware to ESP32-POE, connect usb terminal and test sensor with neodyme magnet.
   2. hall efect sensor detect only north pole of neodyme magnets, therefore try to attach for find north pole and sign it with permanent pen. The output of the closed sensor can be monitored in the CLI on line (1 is open)

       RpmPin 0 | Rain1Pin 1 | Rain2Pin 1

2. Mask all connectors and sensors (U13, U14) and appply protective acrylic

Part #2 designed for mounting tube with 58 mm diameter
For another diameter change value in OpenScad and export new .stl

        MountDia             =   58;   // tube size for mounting

1. Install Arduino IDE
2. Install ESP32 support from GitHub
   1. prefered via board manager
3. Install Arduino libraries
   1. PubSubClient
   2. Adafruit_BMP280_Library
   3. Adafruit_HTU21DF_Library
   4. Adafruit_Unified_Sensor
   5. OneWire (optional if use external DS18B20 temperature sensor)
   6. DallasTemperature (optional if use external DS18B20 temperature sensor)
4. Download firmware from GitGub
5. Select menu Tools/Board:“OLIMEX ESP32-POE”
6. Connect micro USB between ESP32-POE and PC
   1. WARNING: not connect USB cable and POE in same time!
7. Select menu Tools/Port/YOUR-CONNECTED-PORT
8. Upload firmware
9. After firmware upload you can upload next version of the firmware via IP, if you computer in same network. In Arduino IDE shows another choice Network ports
   
10. password for OTA upload is remoteqth

1. After first upload firmware via USB, open serial monitor in Arduino IDE (Ctrl+Shift+M) and set
   1. baudrate to 115200
   2. No Line ending
2. write

   ?

   and press enter show settings Command line interface
   
   

3. Now copy and save
   • IP address
   • Key for telnet access (100 characters)

Key are generated automatically from internal pseudo random generator after start if EEPROM is clear. Therefore you can generate new key after clear EEPROM with E command.

• Download and install PuTTY
• In menu Terminal preset CR/LF and line discipline by picture
  
  
• In main menu Session select or set the following values
  
  
  • select Telnet
  • port 23
  • write IP address (saved from first step acces)
  • Sessions may be saved for next time
  • for connect press Open
• Login confirm with press

  y

• Now answer four times the question of what character is on random selected position, in your key (key saved from first step acces). Key formated in groups of ten - FOR EXAMPLE

  Position  KEY
   1-10     pP75tf8qrF
  11-20     y4SK57dpnC
  21-30     fpag8x9eZ4

  81-90     B68NpG7F0t
  91-100    5mD04pAE6s

• if you enter wrong three times, login will be blocked for next ten minutes
• After login your IP address store to EEPROM and next key will be required only if change your IP address
• Now logged in to CLI (command line interface) via telnet
  
• for Logout press q
  

If open IP address of WX station in web browser, load MQTT-wall.
That propagate every half hour last measured value.

• Prepare hardware components
• Prepare printed patrs
• Prepare electronics PCB
• Passive thermometer sun shield

The screws do not need any nuts because the holes are conical.

1. Check if all parts is present
   
   
2. Trim all soldered THT pin on back side of PCB
   
   
3. Use two screw M3x10 for mount PCB to printed parts number 2 and use two cable tie
   
   
4. Use two screw M3x10 for mount PCB to printed parts number 1
   
   
5. You can seal the hole on the top with silicone
   
   
6. Silicone top hole
   
   
7. Slide in brass threaded rod M6x220mm
   Slide in printed parts number 7 and screw in 2x M2x10
   
   
8. 
   
   
9. Press the bearing into printed parts number 8
   If need precise tuning outside diameter, use this value in OpenScad source

This part needed for accurate measure of temperature.

• First step measure mouting pipe diameter
  
• Download 3d models
  
• Now open source code in OpenScad and change line

  MOUNTDIA  =  42;

• Change the parameter gradually from 1 to 3

  Part  =  1;

  then press F6 and F7 for .STL export this part. Other parts not depend to mounting pipe diameter.

• After complete all STL parts you can start 3D printing with WHITE PETG filament. Sun-shield part nr 4 you print four times.
  

• Check all parts
  
  
  
• Mount three screw M3x10mm for join part 1 and 2
  
  
  
• Plug thermistor to center part 3
  
  
  
• Mount three screw M3x10mm for join every floor
  
  
  
  
  
• For Mount bottom grid with M3x20mm
  
  
  
• Final mounting to pipe
  
  
  
• How connect thermistor to meteostation board

• Three mounting type are available
  • Horizontal pipe - need tune parts number 3 to same diameter and 3d print
  • Vertical pipe - need tune parts number 3 to same diameter and 3d
  • 6mm hole for vertical rod
• During instalation respect orientation by down side sign to South-North orientation

• LoRa firmware support
