C2IS Weatherstation
Early development. Not tested yet.
This is another firmware solution for the famous "Solar Powered WiFi Weather Station" from Open Green Energy: https://www.instructables.com/id/Solar-Powered-WiFi-Weather-Station-V20/
Since I don't like "cloud"-services, I wanted to host everything on my own server and ended up with a mosquitto + Telegraf + InfluxDB + Grafana stack. This is the firmware part. It features OTA updates and device-specific configuration stored in the SPIFFS as a json file.
I replaced the BME280 with a GY-21P shield, which has a BMP280 and a Si7021 on it. My first setup with the BME280 showed me 100 % humidity after a few weeks this winter. The Si7021 has a thin cover, which protects it from corrosion.
