ESP32 Differential Box Monitoring

We need a way to monitor temperature and humidity inside of the differential receiver box, since we're here to monitor, it would be super amazing if we could also monitor all of the DC power consumption as well.

Research

ESP32 Powered as the ESP32 has two(2) I2C ports available.

Temperature and humidity can be an SHT40 sensor from DR Robot as this is a fully I2C functional node.

Power sensing can be done via a DF Robot SEN0291 sensor which is also fully I2C functional.

Power sensing in a custom package can be done via TI INA745B chipset with I2C functionality.

Conjecture

Use an ESP32 module of some class type to be a monitor node. Leverage the I2C bus to monitor temperature, humidity, and power consumption.

Offer a Prometheus endpoint for scrapping / push to a Prometheus PushGateway

Offer an MQTT publisher to push the data via MQTT
