PCB arrived today.

Initial Setup

1. Soldered JP1,2,3 (debug LED, power , and charge indicator)

2. Set to ESP32 DevKit

3. Blink is working and printing to serial console on programmer UART

Initial TODO

•  Hello World!
•  Evaluate charger circuit
•  Add compiler directive for non-Heltec software build
•  ADC review for VBAT
•  ADC review for VSOLAR
•  Digital CHGST pin read
•  Rain gauge interrupt routine back online
•  I2C evaluation with BME280
•  Weather direction evaluation
•  Wind speed evaluation
•  New LoRa radio install for 915MHz
•  Calibrate ADC for VBAT
•  Calibrate ADC for VSOLAR
•  Verify I2C power switch
•  Verify LoRa power switch

Prepped LoRa radio for modifications. I’m using high temperature Kapton tape to insulate pads that I’m intending on soldering jumper wires to.

Not as elegant as planned, but LoRa radio is verified. A total freaking hack job!

...

Sensor → LoRa → MQTT → Home Assistant

•  Data makes it to Home Assistant
•  Rainfall hourly accumulation
•  Rainfall 24h accumulation
•  Wire up DS 1-wire sensor
•  Correct BME temperature in MQTT or HA (unit of measure is wrong)

Home Assistant - Weather sensor data

Home Assistant - Hardware sensor/health data
