## PicoWeatherStationV2
Off-grid, standalone version of [PicoWeatherStation](https://github.com/zNitche/PicoWeatherStation) powered
by [strawberryAPI](https://github.com/zNitche/strawberryAPI).
---
#### Features
- Logging temperature & humidity.
- Logging battery & pv voltage.
- Access to logged data through WiFi hotspot and web app.
- Logs visualisation using `chart.js`.
#### Setup
1. clone repo
2. clone submodules
```
git submodule update --init --recursive
```
3. set `HOTSPOT_SSID` and `HOTSPOT_PASSWORD` in `config.py`
4. set `WEATHER_LOGS_PER_HOUR` in `config.py` (default logging sensors data every 20 minutes).
5. format sd card (FAT32).
6. `chart.js` setup:
rpi pico doesn't have enough space for flashing css/js libs, get `chart.js` from
cdns (`https://cdn.jsdelivr.net/npm/[email protected]/dist/chart.umd.min.js`),
then put it on sd card `/static/libs/chart.js`.
7. flash `RPi Pico`.
