请注意，此程序在处理数据包解密时并不适用，因为似乎最新型号的数据包不再加密。如果由于加密无法获得正确结果，请使用其他选项。

安装

cargo install co2-mini-monitor

您可能需要安装以下内容来构建hidapi-rs。

• libusb-1.0-0-dev
• libudev-dev
• libhidapi-dev

用法示例

InfluxDB

使用jq解析和格式化数据，并使用curl将数据发送到influxdb，如下所示

#!/bin/bash
HOSTNAME="localhost:8086"
ORG="YOUR ORG"
BUCKET="YOUR BUCKET"
TOKEN="YOUR TOKEN"
/usr/local/bin/co2-mini-monitor \
  | /usr/local/bin/jq -r --unbuffered '"\(.type) value=\(.value) \(.time | fromdate)"' \
  | xargs -I{} curl --request POST \
    "http://$HOSTNAME/api/v2/write?org=$ORG&bucket=$BUCKET&precision=s" \
    --header "Authorization: Token $TOKEN" \
    --data-raw {}
